So does Auto Start Stop Technology ruin your engine? Cause more engine wear? Cause premature starter or battery failure? The correct answer is NO IT Doesn't. It actually increases fuel mileage too.
#newtoyou #ford #fordranger - Auta a dopravní prostředky
The start stop feature reduces fuel dilution at idle. Fuel dilution reduces viscosity. Reducing viscosity increases wear. Its been proven by skeptics with oil sampling. Im fine trading internal wear items for external wear.
Finally someone gets it! I actually did a video on this too. It's the 7,258 mile oil change.

Whether it’s harder on your car or not. Or whether it saves you MPG or not. At least we can all agree that auto stop/start is stupid and annoying.
We can all agree on that yes.
It is ridiculous that the OEM 's don't allow for this to be permanently turned off if drivers don't want to use it. I have to push a stupid button every time I start my car in order to disable it.
Yes, agree completely. It is very annoying
@@MrFalcmanwould be even better is you could set a time of when it kicks in, 15 seconds, 20 seconds, etc. And of course with completely off.
So bottom line, yes it's harder on the engine but the engine is built to take it. So, if it's disabled, the engine will even last LONGER because it's not being beaten upon. I have to admit, I'm going to use Forscan to disable it simply because I don't like being told what to do by enviro-whackos.
Not harder on the engine. Maybe a tad bit on the starter and battery. But they are built tonwithstand it. It's like starting your car in the morning. Or running g around doing errands starting it everytime you get it it to go to another place. Stop and go traffic with a vehicle constantly running is bad for an engine. I don't know if forscsn will let you. I haven't tried it with that. I think it will cause you can change buzzer sounds and different things like that.
Yeah. An engine going from off to take off rpms is obviously not good for it. Don’t need a tech to say anything about it.
@johnmadsen37 you obviously have no idea how it works. It doesn't go from off to take off rpms. There is a delay. What about people that start their car first thing in the morning and put it in drive and take off? That went from off on a cold engine to take off rpms real quick. Or does that not apply cause it's not auto start stop? Do your homework please. Maybe you do need a tech to tell you a thing or two. Have a good day
@@johnmadsen37Just because you don't understand something doesn't mean it's bad. Listen to the man with a ton of training and experience.
it saves you gas tho... just saying
My first car was from the 70s and if I didn't let it warm up long enough after starting, it would stall out. Every time I'm in a start/stop car and the engine turns off, I have flash backs to that.
Yeah them older carb cars. I had a 68 mustang I had to pull the choke let it warm up and release the choke and still let it run to warm up. Modern cars you don't have to do that anymore. But I know exactly what you mean 😁
The starter can handle 3 times more starts than a vehicle without auto start/stop. The problem is that if you are a city driver, it will have to start 100x more. So yeah it totally wears your starter out faster.
Incorrect. It doesn't always shut off when stopped in city traffic. There's a counter that gets reset after so many stop starts. Engineers have thought about all this. Especially cities where no idling is allowed. I've talked with engineers. I've worked at dealerships. Some manufacturers design is better than others. I haven't changed a single starter on a stop start system. Except on a Chevrolet in used car once. But honda Subaru and Hyundai have the worst system with lots of flaws. Ford Chevy and dodge have pretty good ones. The one thing that is worse than any auto start system. Is active fuel management. Of displacement on demand. Now those are bad for engines. I always deactivate them.
@@BeardedFordTech I just bought a 2023 F150 on July 30. I can tell you on my 20 min drive to work down main street, if I leave auto start/stop on, it shuts off at every single street light. Theres about 10 of them on my drive. Sometimes it starts back up after 10 seconds or so while im still pressing the break stopped at the light. It's obnoxious and I had to disconnect the Battery monitor from the negative lead on the battery to get it to stop. I ordered a Trailer plug tester off of amazon. So I can just plug that in and the Truck will always think I'm towing something, that way I can plug the battery monitoring back in. Sorry but the stop/start technology is retarded. If I was worried about fuel economy I wouldn't be driving a full size pickup truck.
@thomaserrico5346 yeah mine doesn't stop and start like that. If it's like light after light after light it won't. But if there's a few lights in between it will. But I don't always use it. I'm not saying people do have to or don't. Disconnecting the battery sensor on works on the ranger to deactivate the start stop without triggering any light. You can go into the "diagnostic" menu of your dash. Which has all the cool stuff in there you can't see on your normal dash so you can deactivate it. Otherwise you would need a scan tool and go into programmable parameters and turn it off. The "diagnostic" portion of the dash is used by software developers and engineers. But if you know how to get into it then it does the same thing.
Yep. also the pinion takes a hit as well. I turn the thing off.
@@leecowell8165 if you say so. Thanks for watching. Have a great day
Here is the video for a used oil analysis using auto start stop for 7,258 miles.
czcams.com/video/WMWWtA4YCio/video.html
For me the bigger question is "what is the real value of using these systems?" Manufacturers will tell you fuel economy which, as you described, is marginally true but that's not why they're in the vehicles. Manufacturers don't really care about your fuel savings but they do care about EPA ratings. Including these systems helps them in this area, which is likely why they are including them. Also, and more importantly, peoples driving habits are by far more responsible for poor fuel economy than any other single factor.
My car allows me to disable this function at every start and I always do. I appreciate your perspective but, logically, parts that cycle more will require replacement sooner. I can buy more gas but would rather not buy engine components.
Yes the parts will fail at some point. But it's not any sooner. And the real value. Well for me no real value. I can turn mine off with a button too. I don't always use mine either. The only thing I can think of is those cities that are in those states that have nonidle laws
If the car manufacturers REALLY wanted to save fuel, they would limit the vehicles to posted speed limits. Almost everyone where I live drives 30 or 40 over the limit on the highway, and it's the large SUV and pick up drivers that are the worst. 50mph to 70 mph equals approx. 15% higher fuel consumption.
You hit the nail on the head when you stated driving habits dictate a lot towards fuel mileage. I've always got quite a bit better mileage than what is rated on every vehicle I have owned. Most people always drive like they are in a race with all the other drivers. Another thing I have noticed is the younger generation doesn't leave early enough to allow for unexpected delays. They leave the house at the very last minute and drive like a bat out of hell to make it on time to work or school.
Another scenario that is actually happened to me in real life, what if I’m sitting at a red light when I notice a distracted or drunk driver barreling down on me? Because my truck didn’t have a stoopid Stop System, I was able to move out of the way with only a split second of time to spare. If I had been waiting for my engine to crank, I would’ve been rear ended it at 50 mph.
@davemccage7918 why is everyone saying It takes forever for it to start? All the ford's I've been in start quickly.and your gone. Dodge and Chevrolet. Theirs is very slow to respond.
Can't confirm #1 or #2, but as a mechanic of 17 years I've changed out more starters in the last 3-4 years than I have ever in my career...and they are mostly on these start-stop motors. I work for a Honda/Acura dealership and the Acura's all have it and we replace those starts like crazy. Never ever did before. Most Honda's can go 150-200k on the original starter, and at 800-$1000 a piece that's a good thing.
The Acura's which are Honda's are getting their starters changed out regularly around 100,000-125,000 and they're the same starter as in the Honda's. I know this is the same issue in Dodge since I"ve brought up this issue with piers. I cannot confirm with Ford because I don't know anyone personally that works at a Ford dealership.
I have a Acura MDX and I installed a idlestopper to prevent premature wear and annoying as hell starts at traffic lights.
I've never had to replace one on a ford cause of autostart stop. Hondas technology in that department is kind of behind. Same with Hyundai. The autostart stop on ford's is actually pretty robust.
A recent report is not looking good for Ford Edge, 20217 and 2018 with Start / Stop are having Flywheel ring gear cracks, very expensive to fix. I disabled my Start / Stop on my 2020 Ford Edge and I am very happy! @@BeardedFordTech
@@jefferysurratt5650 Crack on the flywheel for 2017-18 was a known issue. There was a TSB for it. Whoever the manufacturer was cheaper out on material. They changed manufacturers. That wasn't caused by auto start stop. But. I see where people think it may have been. I don't always use mine as stated many times.
Very frustrating, having to replace starter in 2018 f150 lariat 3.5 after only 54k miles
@stevepauley-os7rn There was a bad run of them. I replaced one under warranty but that was in 2019.
I found a really easy free way to disable auto start stop on a 2023 F150 without doing anything thar would void your warranty or damage your vehicle in any way. On your infotainment system, go into features, then tap on towing, tap on select active trailer. Select default trailer. Done. Doesn't effect the backup camera at all. You're welcome. Im going to post my own video so everyone knows.
Yeah it thinks a trailer is connected. On a ranger you can just disconnect the battery monitor sensor. It won't throw a light. But that's the only one we found that won't throw a light if you do that. I'll pin your comment so others can see
Does that affect the back up camera?
@@booterone1 nope
@@BeardedFordTechI’m confused as to why people want to go through the trouble to permanently disable it. It takes literally 1/2 second to press the disable button when they start the car.
My 2023 has a auto start/stop on/off button.....lol
I’m used to getting lied to by politicians and people trying to sell me something. As an engine builder I can say that there is no way it’s not causing more wear on a motor constantly losing the bearing cushion that oil pressure creates. I’m willing to wager these motors don’t hold up like a normal engine. Nothing new last like stuff used to just 15 years ago. Everything is made disposable now days. I have seen a number of these start stop vehicles with bearing knock by the way.
I haven't seen any with bearing knock( not saying it doesn't happen) but there is an axillary pump that keeps oil pressure. At least on ford anyway. You may be an engine builder. But are you building these new engines? Not saying they don't fail because of it. Everything is built to fail nowadays. But it doesn't fail any sooner or later. I bet if you dig a little deeper on the engine knock. How were they with doing oil changes and keeping up on maintenance cause that is a big factor. People will neglect the simplest maintenance things then blame a system on the car for the failure when it was actually the user. The problem was between the seat and the steering wheel. I see both sides. I get it.
I see it more on the audi and vw cars with the first generation stop start system quite often and it usually happens just outside of warranty. Im convinced all this techno crap on cars now days is to make sure they cant be kept around for very long because they arnt worth fixing. I also cant help but wonder if Ford ever got over their hard work at trying to find the perfect formula for engines that grenade just outside the warranty. They were so close on the 2011 scorpions and the 2.0s 😆Cars after 2005 just seem like such techno trash its ridiculous. @@BeardedFordTech
@@volatile2805 yeah. Nothing is built to last anymore. It's all part of their plan.
100 percent. I've been an automotive engineer for over 25 years and all of this is total BS
The plan is First make cars expensive crappy and complicated then get rid of them altogether.
Basically. They are trying hard too
I’m not an auto mechanic, but being a maintenance mechanic I know anything short cycling is hard on the equipment. If the only savings is 7 percent max, it’s definitely going to cost you more in wear and tear than that tiny bit of fuel economy.
I though so too. For a very long time. Just did an used oil analysis. It says otherwise. No wear. I get why people think nit wears things out. But they are comparing older engines to modern engines. I see both sides. But used oil analysis tells you what's going on. There is no bearing or piston wear. No gear wear going on. Wear rate is very very very low. Video should be up this weekend
@@BeardedFordTechhow about the wear on the starter and battery? I know they just add haveavy duty to compensate but it would just all last long
@chrisdsx6839 it wears out. It's a mechanical part (starter) but not any sooner than one without it. As far as the battery. They all only last about 3 years now. Go to any parts store and look at them. They all went from 5 to 3..
@@BeardedFordTech well I'm going to get an auto stop eliminator because I don't like how it feels when I'm driving. i imagine not making the starter star an extra 20 times a day will make it last longer...
@chrisdsx6839 you don't like how it feels when your driving? Makes no sense. The engine is running. Why buy an eliminator? If you have a ford you can deactivate it. Permanently too. I don't know about other brands.
Nice explanation, but its my #1 most hated feature ever put on a vehicle.
All good. Don't have to like it. Some do some don't. I actually do like it. Instead of idling washing out the cylinders with fuel and diluting the oil even more. I don't always use it though.
@@BeardedFordTech Diluting the oil by idling at a red light is a problem all of a sudden in 2023-2024, huh? At work we have a 2013 fleet vehicle with the Ford 2.0L Ecoboost, over 200k miles and probably another 200k of idling on it and it's still on the original engine / turbo with regular oil changes. All that oil dilution narrative is just corporate apologism for a "feature" that 95% of owners seem to HATE, whereas in reality it's only there to meet the CAFE standards for FoMoCo. At least give us the option of turning the damn thing off permanently, without aftermarket gizmos!
@SevenSixTwo2012 oil diluting from fuel has been around for a very long time. My oil analysis video literally shows you. It is a real thing. Not just 2023-2024. Pull the dipstick on your fleet vehicle. Bet it smells like gas. Get it tested. Bet it has fuel dilution. It's the number one killer of oil. Inrun a fleet of 180 vehicles gas and diesel. I'm not saying people have to use it. And I literally just said if you have a ford email me. You don't have to buy a gizmo to permanent turn it off. Instead of arguing listen. YOU DONT NEED A GIZMO TO PERMANTLY DISABLE IT. Yet everyone thinks you do. And that. I find funny. If people want to waste their money with gizmos to turn it off. By all means go ahead. But it's literally not necessary.
@@BeardedFordTechI need a gizmo to turn it off in my 2017 vehicle. But the plus side it was only $17.
one question. If it doesnt wear out the starter, why would they have to make it more robust? Face it, the engineers knew the starter was going to wear out. The cars get better gas mileage at the expense of wear and tear on the engine because the oil stops circulating when the car is off, the battery is also being charged and discharged harder.
Incorrect. That's why the starter doesn't wear out. In ford (and a few other brands) the transmission and the engine actually have a little electric pump that keeps fluid pressurized and slightly flowing. Engineers are actually pretty smart people (most of them). So your not really putting wear and tear on the engine. You do more harm letting it sit there and idle letting fuel wash out the cylinders diluting oil. Therefore having to change oil more often. There's pros and cons. I don't use mine all the time
That is why us smart people change our oil every 5,000 miles, oil is cheap, engines are not and stop start systems are a JOKE! I will disable every start stop system on any car I own. No flywheel problems for me, thank you. @@BeardedFordTech
@jefferysurratt5650 I change my oil every 5k. But what does oil have to do with the flywheel?
a little gas is cheaper than a starter replacement
@bikeman1x11 if your shopping after market or not knowing where to buy. The one for thus truck is 248.98 walk in price at a dealer without a discount. Oreillys and advance auto. Exact same starter. 479. They mark theirs up so high its crazy. And people really don't realize this. There are ways to disable it. That I'm not going to say. Because if it bothers someone enough. They will figure it out. Or. They can press the button. No different rhat using a turn signal or buckling your seat belt. Just push the button if you don't want it. It's done by the epa for cities with no idle laws. And eventually you won't be able to turn it off.
My new car features this ridiculous idea. What you're telling me is that I get a higher quality starter due to this, which I really like. I'm disabling auto stop either way, but as far as wear and tear, induction hardened gears are induction hardened gears. The only other thing they can do with them is put a coating on them. They wear. I don't want a starter constantly engaging, it wears stuff out.
No different than you starting it in the morning then going to the store shutting it off and starting it. Going and doing everyday errands. Does it get worn out? Sure it does just like any other vehicle. But not faster or slower.
I think the point he was making is auto start/stop regardless of quality or method of implementation adds additional wear on the starter and gears. Same drive to the grocery store now might have 10x the "wear" than without it. The feature is more beneficial to the manufacturer than the owner is the point.
@@Mortanon I can see that point of view as well. I'm not saying it doesn't go bad. Sure it does. But not quicker or slower. They seem to last about the same from what I've seen.
@@BeardedFordTech oh wow, thanks for replying man! Question, if these new starters are possibly this much more robust, why aren't they designed into all vehicles even those without start/stop?
@@Mortanon that is a very good question. And the only thing I could find out from engineers is that the internals are just made of stronger material. A vehicle without auto start stop apparently doesn't need it. And to be honest I disagree with him. I think it would make much more sense if they all had parts made with stronger materials. It's a cat and mouse game. I don't use my auto start stop all the time. I give it a break now and again. After 10,000 start/stops the counter has to be reset anyway.
Hybrid systems have engines that start stop all the time, yet 300k mile hybrid Toyotas are still running in the wild
A gasoline start stop system is considered form of hybrid. I found that out a few months ago
This was a very helpful video. My car doesnt have an autostart and stop system but I think ill wait until i get a scangauge to monitor my coolent and oil temps with the engine off, ill just have my own "manual start stop."
If your sitting for a little bit you may see coolant temp rise due to a "hot soak". Basically heat rises and it hits the hood and just circulates under there. The hot coolant isn't being circulated so it just sits and gets hit. A auto start stop system has an auxiliary coolant pump that keeps it flowing. But there's no air movement cause you aren't moving. But the temp won't rise because it's being circulated. I like where your going with this.
With all the new features added to cars lately from flat panels and menus systems you have to scroll though which completely distracts you when driving to auto-start, auto-start is the feature I hate the most. The people who forced this idea on us should be forced to live out there days covered in fire ants. I feel better now. 😉
I used to hate start stop. But I like it now. As far as all the other features they are giving consumers what they want and it still isn't enough.
@@BeardedFordTech - Haha, they're clearly not asking me. I can think of 3 cars right now that if they made them again I would go out and buy one in a heart beat. The old Honda Prelude like back from 1988, or the '88 Integra or an '88 Civic CRX Si. When I look at a new '23 all I see is tons of distractions from driving and tons of expensive things that will break after the warranty expires.
@@abikeanditsboy3449 agreed.
I just wish it was a feature you opted into versus being forced to opt out every time you turn on your vehicle. I’m lucky that my auto start/stop toggle button is right next to where my phone goes so it’s just muscle memory now. Plug in phone -> press button-> put into gear.
My father always forgets because his is below the turn signals, and not easy to find without looking.
I agree this stop/start is 💩💩
Thanks for the education. I just bought a used 2019 F-150 and I had no clue or understanding about Auto Start.
Your welcome. I did a video about a year ago. Possibly more about how it works. Check that out. And mile 7000 mile oil change using auto start stop. Check that out if you get a chance too.
My man listened and believed everything the salesman said.
Salesman sell cars. They know nothing about them. Ask a technician.
@@BeardedFordTech I think that guy insulted you. You didn't get it?
Very informative video. On a half ton pickup, 7% better mileage is about 1.5 miles per gallon. Just trust that the automakers are using better parts for stop start. I will stick with my 2007 Saturn with a manual transmission thank you. If my engine ever stops, just give it a push, pop the cluctch. Start! LOL
That's what harder and harder to find is a manual transmission. I would have gotten one. 1.5 miles pergallon adds up. But at the same time it's not a lot is it.
I don't like it. It doesn't make sense. It has resulted in some negative effects. The logic of physics tells you that.
Used oil analysis says otherwise.
@@BeardedFordTech I mean on the starter mostly. I live in a city. On my way to work, I have to stop at twenty traffic lights and ten stop signs. The stop-start system would have to be fifty times better than a regular starter. No thanks.
@romanc.5074 it shouldn't stop at every light or stop sign. There is a counter for how many times it does it in a certain amount of time. I get why people think it wears out the starter. But they also aren't thinking on how the system works or know how it works. I see both sides. And if people don't want it or want to use it that's cool their choice. I'm not trying to say you have to use it. But more engine wear occurs at idle. From fuel dilution. It was also made for cities with no idle laws. I'm okay with it either way.
Absolutely not a doubt in my mind that start /stop is the most ridiculously stupid technology in as long as I can remember in the auto industry.
Oh there's more stupid ones. Like dpf filters and egrs. EGR reduces heat. But then you need heat to burn off the soot. So now we are back to heat only to be cooled again by an EGR. How about gasoline particulate filters? Oh here is a good one. Probably the most ridiculously stupid technology. Ready. Electric vehicles. There's more things out there that are stupid. I never said start stop wasn't stupid. Or that anyone has to use it. There if they want it. Things have changed since people's great great grand dad worked on stuff. It's not like it used to be.
One of those "better ideas from Ford right", I believe that it will compromise the life of the starter especially if that vehicle is driven in one of those dirty old cities with wall to wall traffic. I've disabled the stop/start and we are much happier with our Aviator.
So ford wasn't the one to come up with it. It was actually Toyota in 1974 with the Toyota crown. So it's not new tech. So don't assume. And using it greatly reduces engine wear. Might want to go check the video I did with 7200 mile oil change using auto start stop. Is it for everyone? No. Does it wear out the starter or battery faster? No. It's more of a preference thing. If you don't want to use it and are happy that way that's all fine and dandy. Not telling anyone they have to. Have a great day. And you drive an aviator. Which is Lincoln. Which is the same as ford with a different badge. Uses all the same software.
Interesting conversation. My concern would be a hot spinning turbo going dry for those moments until it spools down .
Not really. Concern on a ecoboost. It won't slin dry though. Dieselnwont spin dry. They spin after you shut them down. I did a short/video on it. That's why you let a turbo cool down. There's a short on that too.
@BeardedFordTech
Accurate. My large turbo diesel trucks I let idle down and cool for a couple minutes. The new start/ stop features are new to me on our new vehicle
@billfincher8519 yes. The diesel you let it cool for a few min to bring Temps down. Start stop system is designed way different.
Let’s see how long these starters last over time after being “beat on” for years. The worst part is the sheer annoyance these systems are, including turning off only to turn right back on in milliseconds, and doing so in scorching heat.
Mines been going strong for 4 years. It won't shut off in scorching heat if your ac is on max. Or super cold if your heat is on max. Or defroster are on. I did a video a while back on how the system works. Go check that out. Learn about it. Don't just use what you think will happen. I get it people think it wears out quicker and you think k it would. I see both sides. But take the time to learn how the system operates first.
My daily driver is a Suzuki Alto Turbo RS with this function. This is a 2015 model and never disabled this feature. Almost 8 years and 4 batters later, the starter still going strong. System works like a charm. Learn about the system before you come up with your own redneck theories man.
@@BeardedFordTechI was gonna ask about how stop/start affected the A/C system. I'm in the Gulf South, so it's a concern. Thanks for the info.
@Urugami45 if the can temp is the same and uts not on max ac then the engine will shut off. But as soon as the pressures drop on the ac or a flucation in cab temp it starts back up. As long as you have it on max it won't shut off. It says "normal operation" under start stop. But when you stop it will change to "heating or cooling"
I have a 2017 F150 with almost 90k miles on it, it hasn't had any problems because of the stop/start.
The only good thing about start/stop system is that the engine parts and electric parts are better than a regular car and you can cancel the start/stop system and have a better car over all but without the incoveniance of starting the engine at every few minutes in town !
That's the whole point. It was made for cities with no idle laws. To shut off. Then the epa made it for all vehicles cause of California. They all have to be CARB compliant.
Thank you sir
You answered my question which is restarting the engine and the oil goes down in the pan.
Yep. It all doesn't go down in the bottom of the pan. That's a misconception. Think of it like an oil change. It's off longer for that and there's still plenty of oil for restart. The auto start stop there is literally not enough time for it all to drain back in the pan. Plenty of oil still on the top end of the engine. 💯💯👍👍
I am a Ford guy but when I had a recall fixed the dealership gave me a new F-150 eco boost 10spd XLT and I HATED it! I wish Ford would just make a V-8 4X4 no back seat long box no touch screen no bullshit interior and no bullshit "features" that nobody needs or wants and give me a key back.
Yeah I don't like the 10spd. They gave you a truck for a recall fix? What recall was it? It's not just ford that does these features. They all do it. Apparently.more of the population wants it (some of it epa controlled) and when people get what they asked for. They don't like it. I'm cool either way. As long as I can get from point A to point B.
I'm not driving a Ford now but am looking to buy something new. When I first heard about this auto start stop I actually thought it was cool because who doesn't want to save gas? After experiencing the auto start stop, my number one requirement for my next purchase is the auto start stop being easy to permanently disable. My current SUV is 3 years old and it tells you your "savings" from the auto start stop. I left it on for about 3,000 miles including lots of stop and go and it said I had saved about 0.3 gallons of gas. I don't keep something past 100,000 miles so the math told me I might save about $100 total in gas over the life of the vehicle. How much extra did the SUV cost to build because of this ridiculous feature? How much extra did I pay for it? The dealer even told me the battery was more expensive to replace than normal batteries. It cuts off at the stupidest times. It's unbelievable, when I pull into a parking space or my garage it cuts off but when I shift the car into park, it restarts! Then I have to immediately cut it back off because I am parking the car. I probably paid an extra $500 (manufacturer is going to recoup their R & D cost and increased production cost) for the car because of the cost of this feature that nobody wants and all it does is make your battery more expensive to replace (even if it doesn't wear out quicker or even if you don't have to do maintenance on anything in the start stop system). The constant vibration from starting and stopping is annoying, the gas savings are almost nonexistent (I even tried it again when gas prices went up last year and the it still saved me something like $1 over a couple thousand miles) plus it just makes people angry that the automakers don't make it where you can disable it permanently. All settings should remember where you had them set when you cut the engine off and restore to what you had when the engine restarts.
Good observations. But you can permanently disable it. I've done it on many ford vehicles. You have to use the computer to do it. If you only saved .3 gallons then something else was going on. I understand not everyone likes it. I don't even use mine all the time. I was just breaking the myths out there because a few people had a battery go bad and blame the system when in fact it was just a crap battery. Even vehicles that don't have it have AGM batteries for all the modules and electronics onboard. Base model vehicles usually have the acid filled. So even if you got a premium model without auto start stop it would still have an AGM battery. I'm not telling people to use it or not. Completely their decision. It's a good feature for stop and go city traffic. And cities where you aren't allowed to idle your vehicle. That's really where it started at.
Atlanta is one of those places where drivers are incredibly hostile and aggressive. The last thing I need is to stop at an intersection and need to go in a hurry and my engine stops. That delay is going to get me killed one day.
I can see that. I've been through Atlanta many time. Fulton county. Speed limit was like 55 and everyone is running 80. I can very clearly see your point.
My 2019 VW Atlas with 75K miles doesn't always use it, often if I have the AC running or even if its barely on it gives me a message that the engine needs to be used for climate control and won't use start/stop. Also, It won't auto start stop in what it deems to be a traffic situation, but which is not always true. I'll just be sitting at a red light. I have to actively think not to inch up any closer or the system engages and puts me into traffic mode. A whole lot of Tech going on for me and hearing that engine constantly starting isn't my favorite thing.
It has its perks. And downfalls. VW is a little different. Same concept. Different parameters
@@BeardedFordTech thanks for the response. do you think based on what I am saying above, decisions regarding using it or not change from your presentation?
Excellent explanation and video Sir thank you.
Your very welcome sir.
Absorbent Glass Mat (AGM) batteries still do have Sulphuric Acid and water as the electrolyte exactly the same as conventionally constructed lead-acid batteries. 👍🛠

Auto start stop and cylider deactivation is something most do not want. Its good to offer it but they should offer it without.
It's like 50/50. Even some people who don't want it live in no idle cities. So they are kind of screwed on that one. Cylinder deactivation on the other hand. I don't think anybody wants.
I live in Alberta Canada where temps reach -35 degrees, when you push the stop start with the brake on and it doesn’t start make sure you keep your foot on the brake before trying again, if you take it off, the booster, being already pumped up won’t push down far enough to allow a second start.
🤔🤔
Three things to avoid when buying an automobile: CVT’s, turbos, and auto-start. The auto-start solves a problem that never existed and adds unnecessary complexity.
Might as well buy a bicycle then.
@@BeardedFordTech That guy was totally right. Why just dismiss him like that?
Start stop features have been proven, with science, to reduce fuel dilution which is one of the main factors in reduced oil viscosity. Oil viscosity is the most important factor protecting engine internals.
@@jmc6940 Non sense. For 50 years, people have changed their engine oil every 3000 or 4000 miles, and did the other required maintenance too. A Honda or Toyota engine will easily last 200,000 miles, and fuel dilution makes no difference.
I don't see anything wrong with turbos imho.
It is just a matter of preference.
But, nothing to fear imho.
Any engineer(not working for the auto industry) knows that starting and stopping rotating machinery , e.g., a car engine, for one, leads to premature failure. The [engine's] attached oil pump only provides lubrication when the engine is running. It does not provide full oil flow instantly when the engine is started. A Start/Stop engine feature is a good way to sell more vehicles.
True to a point. But testing showed it doesn't wear out the engine any faster. Or the starter. The main killer of engines. Not doing oil changes. I don't care if it has auto start stop or not. I have the tools to turn it off if I don't want it. Some people do. Some people don't. Some people don't mind either way. My dad hates it on his f150. He turns it off. And that's okay. It's mainly for people who live in cities with no idle laws. And they just put it on every vehicle.
The cost of a new starter as opposed to the "savings" of less idle time is financial. Do the math of 60,000mi replacement as opposed to 100,00 mi replacement. don't forget the wear and tear on the pressure plate gearing.$1000 a pop for starter(if lucky) is a lot of gas, not sure if it equilbrate$.@@BeardedFordTech
@@molarguy so my truck that has 60k miles on it now the starter is just going to go out because of start stop. Notated. Thanks for the heads up.
I have 2 cars the same make, different years. Both have stop-start. The one I drive is the older and the system works like a dream. I have auto hold too. I don’t understand people that don’t like it or think it’s stupid. But I guess that’s their opinion and mine being different. I can stop at a set of lights that I’ve just seen change to red and keep my foot on the brake and save a heap of fuel. If I can see the light will change to green I lift foot off and auto hold keeps me stationary while the engine starts. If the opposing lights are changing as I approach I just let auto hold take the car and only hold the brake long enough to stop the car, not the engine. Works so fantastic…. In fact when it’s not up to temp, I really miss it….
The car my wife drives is 9 years newer and the system sucks. It stops the engine before the vehicle stops, so if you’re simply slowing to meet a light that is changing as you approach it stops and immediately to start…. Very silly system… I don’t understand why they changed it….
It shouldn't shutoff before the vehicle stops. That's bad. The vehicle is supposed to come to a full stop then shut off if all parameters are met. Auto hold is cool. Mine has hill assist. If you let you foot off the brake it holds you from rolling backwards.
@@BeardedFordTech shouldn’t being dependent on brand. I addressed it with the service manager at VW and he confirmed that is how the new models behave….
@@rudolphvanthoff1391 that's weird
Excellent explanation and video. Thanks very much
Your very welcome.
Stop start, a solution to a promlem we never had, how come if I am queuing at macdonalds the stop start works for around 3 times then gives up, also a youtuber worked out over the years he has had his car it's only saved around 14 mile of fuel and you are totally correct it won't damage your engine, but the battery and starter sure takes a hammering.
Battery more than a starter. And if it did it in the drive through three times then it realized it stopped too many times in a short amount of time. This is to keep it from ruling your battery and starter. You kind of answered your own question and didn't realize it. But that is why it does that in the drive through.
No start stop: starter motor used once per trip. With start stop its used 30 times more. Is starter 30+ times more engineered? Is it made of Vibranium from Wakanda?
Seriously. Obviously you aren't picking up what I'm setting down. How many times it starts and stops depends on many factors. And the internals of the starter are build more robust than a normal starter to withstand the restarts. Why is this so hard for people to understand. It's just more robust. Does the starter wear out? Yes of course. But no sooner than a normal starter.
I know a person that had a Auto Stop Start in their Ford that the starter failed with under 50,000 miles on it and Ford wouldn't repair it under warranty, 1½ years old. I'm driving a 2000 Toyota Tacoma pickup with 238,000 miles with the original starter in it, only needed to have the starter contacts cleaned once. I think I'll keep driving my Tacoma!😂
Saw a report that 2017 and 2018 Ford Edge are having problems with Flywheel ring gear cracking, very expensive to fix. Start/Stop systems are so car makers can get better results in the EPA city driving portion of the test. In real world driving they are a pain as they do not turn the engine back on fast enough and I have people honking at me. I just do not like them. With the flywheel problems I am glad I disabled my Start / Stop system for good, a year ago on my 2020 Ford Edge. Good to know that my starter will last years longer because I am not using Start / Stop and do not have to remember to push an extra button each time I start the car.
Yeah it will last even longer if your not using it. But if it was cranking slow then that could be another issue. When I use mine e it cranks fast. I've notice some Chevy vehicles crank slow as well. As long as you love your vehicle that's all that matters. And I'm glad you love your edge.
All based on the word of the manufacture… their interest is to make it work well enough for their product line average MPG for federal regulations and to last long enough for the warranty coverage period…
So mine is way out of warranty still running strong. Is it for regulations? Of course. They are just doing what they are told. Your a little off on the warranty part though.
There's still another point to all of this even though the starter in the turbos and whatever else maybe built with higher quality materials and design to withstand the constant starting and shutting off in all reality if you were to disable the auto stop start feature permanently these same parts would last twice as long than if you left AutoStart feature on for the life of your car. Therefore auto stop start is still contributing to extra wear that isn't necessary. Unless you are willing to exchange that wear for a 5 percent difference in gas mileage. I personally am not willing to exchange that and there are plenty of aftermarket modules that you can buy that just plug directly in and permanently disable the auto stop start so you don't have to push the button every time you get in your car and start the engine.
True. Just starting your car in the morning does the same thing. I don't need a module to shut it off. I have a fors computer that I can do lots of things with. But for the normal everyday consumer yeah. But did you know there is other ways with a module to plug in. And no I'm not going to tell you cause I'm not about to get in trouble for that.
I agree with you. I disabled the start/stop on my 18 F150 5.0 shortly after buying it new. Gawd I hated when it shut off. 80,000 miles later, no problems with the original starter or battery. With the system deactivated, I average 20mpg in my 50/50 city/highway driving.
I get it but you are not going to convince me that the starter is that much more robust. Especially with the reduction of quality in auto parts across the board over the past decade. What I hear is "with Auto Start/Stop system we just didn't reduce the amount quality in the starter". Lol, my other concern is the transmission components constantly rengaging at odd intervals. Other than that it is just really uncomfortable.taking off from a light sucks! Lol
It is more robust. And if you like it cool. If you don't. That's cool too. As far as the transmission. There is a electronic motor in there that keeps fluid pressure. It stops and starts just like the engine. The transmission is just clutch packs and planetary gears. Your not actually changing gears. Just changing the ratio. But I see where your concern is.
Just more stuff that can fail, how do you know the extra motor in the trans is working correctly?? Too many unanswered questions about these systems, just more work for the mechanics who work on these systems. KISS Keep It Simple Stupid. @@BeardedFordTech
@jefferysurratt5650 yeah I work on these all the time. They can be comicated. Let me ask you this. You change your oil every 5k. That's good. Have you had a transmission service yet? How many miles on your 2020
Just disable the system. Engine stays running. I’m not sure how I will sleep at night knowing that I have wasted one extra drip of fuel
👌
Bottom line, it’s like EV’s, the promise that you will use less “gasoline” might be true, BUT, like most Government ideas, they’re usually shortsighted. The EV concept is built on a total package of concepts that depend on each concept to be viable. The Electric Grid is powered mostly by coal in the USA, and had we moved to nuclear energy 30 years ago we would have the power that would sustain an all electric lifestyle but we don’t. Had we moved in with newer salt batteries rather than use a foreign based lithium battery systems, we also would’ve in a better position, but we didn’t.
Having digressed to,this point, I want to get to my end point in that the EV and Hybrid EV’s have the batteries as a connection. When you have ALL these new and even beneficial technologies in our vehicles incorporated into our vehicles they require a lot of battery capacity. This brings up a couple of things that seem to lost on the audience. First, when you drive your vehicle with all the gadgets, they’re using a lot of electricity and to keep up with their power consumption needs they must have big alternators and big batteries, with a backup battery.
What with all the WiFi connection and Bluetooth connections there is something connecting to your vehicle all the time, like Onstar, Navigation, key fobs, and now government agencies want to connect to your vehicle for surveillance like driver mentality, how they’re talking, where they’re going, where they’ve been.
According to some publications we can expect a mileage tracker for mileage taxation, a tracker for your license plate accountability, the driver mental function tracking is expected by 2025, and the mileage tracker is already in the works.
So knowing all that, finding that the Auto Starting is Stop/Start and it ties into the biliary to SHUT YOUR VEHICLE OFF if they don’t like your attitude.
So when you stop at these traffic signals and your engine shuts off, who’s charging the huge batteries? Expect that your vehicle will be sending you a text, an alert, or a voice warning that you need to replace those batteries OFTEN. ABOUT $1000 a pop, and have you seen both of those batteries lately?
Okay. Both of what batteries? Iy has one. And it's like $250. I can agree that they did talk about mileage tracker and such. Hell onstar can shut your car off. And yes like 99% is government crap. Batteries only last like 3 years now anyway. Where is this 1000 dollars coming from and two batteries? On a ranger? Dodge uses two batteries. A small one like a motorcycle battery for their start stop.
Good job at disproving all the myths surrounding start-stop. However, it's still annoying as all get out! I've had it turned off permanently on our vehicles. It's just another government regulation that costs us money and headaches and only makes a certain part of our society "feel" good.
Yep. It can be annoying. But when working properly.czn be a benefit. They're way more behind of why it was made. But that will be another video one day. Thanks for watching enjoy your day
those "myths" are the facts-- anything being used more will fail sooner- if i get a vehicle with this BS its being disabled ASAP- I had a subaru outback with the DRL's and i was going through headlight bulbs like crazy- disabled it
We are buying (soon) a 2018 Ford Escape Titanium with 31k miles and it's absolutely loaded with every option known to mankind. I was not concerned about this feature until I went down that rabbit hole watching video after video about all the negativity surrounding the feature. I'm glad I clicked on one more video to put my mind at ease because I almost thought about NOT buying it. How silly of me. I was listening to a bunch of armchair mechanics who have no clue what they are talking about. You'd think I'd learn. Thanks for setting the record straight man.
That's exactly why I put this video out. Someone has a problem one time and they blame it on auto start stop when in reality that wasn't the issue. Glad I could break that barrier for you! Enjoy your new ride. Reach out if you have any questions.
You can usually bypass them too.
@@patm95 yep. On the ranger just unplug the battery monitor sensor. (you didn't hear that from me). If you have a scan tool that does programming. You can turn them off .
Watch out for flywheel ring gear cracks -see my post below
I was walking through a parking lot and someone in a Ford with the A.S.S. system stopped to let me walk in front of them and the engine shutoff. When they tried to drive the engine cranked for an extended period of time before it started.
If it was a new one then they have another issue going on. If it was an older one then may be time for some spark plugs. I've seen them due for plugs and it does extended crank. Do a tune-up and it all went back to normal. If it was a newer one then it's just the crank sensor looking for top dead center counting teeth. It has to do so many rotations to verify. The crank sensors on these new ones are weird. Very very finicky too.
I recently got a 2018 equinox 2.0. Didn’t realize how annoying the start stop was and of course being GM you can’t turn it off without some pigtail/bypass or driving in Low maxed out, all the time which is equally annoying
Yeah I think 2019 or 2020 and newer gm you can turn it off
The auto start-stop system in the 3.5L Ecoboost engine does have an impact on the turbos, but it's important to understand the design and functionality to address any concerns.
During an auto start-stop event, when the engine shuts off, the turbos do continue to spin for a short period. However, it's worth noting that the turbos on modern vehicles are designed to withstand these conditions. They are built with high-quality materials and incorporate sophisticated engineering to ensure durability and performance.
Additionally, even though the engine is off, the turbos receive lubrication from the engine oil that remains in the system. Modern engines have advanced oil circulation systems that continue to supply lubrication to critical components, including the turbos, even during brief periods of engine shutdown.
Automakers also take measures to minimize wear and tear on the turbos. For instance, the auto start-stop system is typically programmed to avoid shutting off the engine when the turbos are operating at high RPMs or under heavy load. This helps prevent potential issues and ensures that the turbos receive adequate lubrication during normal driving conditions.
Nailed it. Same with the 2.3 Ecoboost like in my ranger. Also the turbo on the 6.7 powerstroke still spins when shut off. I did a video on that cause someone wanted to see it soon. Great explanation.
"They are built with high-quality materials and incorporate sophisticated engineering to ensure durability and performance." I just had to laugh at that one. Too many recalls and TSBs for that to be remotely accurate. Chevy Bolt owners I think would disagree as well. If your car randomly becomes a bonfire, that sure is some amazing engineering. Yes indeed. It's a long long list of problems with new and used unmodified vehicles.
I was looking for this information. I have a new Silverado turbo and besides hating the start/stop, I turn it off religiously cause I thought it was bad for the turbo but on the other I figured they had to of thought of that.
remember too that the manufacturer is designing to get past warranty. After that, do you think they really care if some people have to replace turbo's?@@Fjord_Driver
Turbo spins when it's shut off??? How does it do that?
It spins down when the engine shuts off, but unless it has an electric motor attached to it, it isn't going to continue spinning without some exhaust flow to drive it.
My concern is that in stop and go traffic on a hot summer day, you'd actually want to have oil and coolant circulating the engine. If you take that away from the engine every time you come across a red light, wouldn't that be bad for it?
No. For a few reasons. 1. It doesn't do it at every red light if they are close together. 2. Oil Isn't going to drain back in the pan that fast. 3. There's an auxiliary coolant pump that keeps coolant flowing when engine is stopped, That's why the temp doesn't rise from a hot soak and coolant isn't just sitting there like if you shut your engine off.
Im not sure if you were with nissan when we came out with stop statt finally but on the rogue the alternator is now called a generator/substarter, charges and then starts the engine during start stop using 48v to spin the alternator and spins the crank using the drive belt 🤯 the belt tensioner on that is pretty neat IMO
Yeah some call them generators. Some call them alternators. Some vehicles use the starter. I think BMW uses compression like a diesel. So many different variations. But all do the same thing. I don't know when stopnstart came out on Nissan. I know ford you started seeing it more on 2015+ trucks. Cars were a little sooner.
The first vehicle to have it was the Toyota Crown in 1974. So it's been around for a while. Subaru started it in 2018 and they all thought it was some new high tech technology when in fact other manufacturers been using it for a while. Then again it's a Subaru. Nothing special about it
Another issue not mentioned in start/stop system is it is so bad for autos with turbos. Many people don't know but the oil cooling lines get clogged from burnt oil in those lines. It happens way quicker than people realize. Nice video though. I personally shut mine off as soon I start my car.
Liquid cooled turbo also not just oil cooled on these ecoboost. Keep it maintained. Oil lines should be clean. I took mine off (oil line) to check the filter. Clean as can be did my coolant last year
Thanks for explaining the auto start stop system. They put enough redundant safety features on it. I expected that it would put extra strain on the battery and starter. I remember the video where you changed the battery in your Ranger due to the A.S.S. not working because of battery age. Engines use more fuel at idle than they do at speed. The A.S.S system would be of benefit in stop and go traffic. Stop and go traffic is a constant daily issue on the section of I95 that runs through our state. I hate travelling on I95.
Yeah stop and go is where it comes in handy. It actually doesn't put a lot of strain on the battery. Or the starter. You think it would but those two items are built more robust. Most of the electronics put more strain on the battery than the starter.
@@BeardedFordTech All those computers memory functions keep a constant parasitic draw on the batteries. Why batteries don't last like they used to.
The only downside I can think of is those of us with older cars where the air conditioning is not worth fixing I have to listen to the car stopping and starting over and over and over again. I now have a car with working air conditioning it's no longer a problem for me. It's just something I experienced.
@@robertknight4672 👍👍😁😁
@@robertknight4672huh? You are complaining about others cars?? LOL
What about HVAC actuators/blend doors? Are they constantly resetting to a neutral position when the engine turns off and then going back to where they were before shutting off? Also the battery and starter may be built better but that means they are more expensive when they do break, and they will let’s be honest batteries and starters are one of the most changed parts on vehicles.
Batteries yes. Mine was like $200. The actuators and HVAC do not go back to the neutral position. That's only when the vehicle completely off as in you turn the key off. That's why if you have ac or heat on it still blows but the heat temp will drop or ac will start to get warm. That's when it starts back up to regulate the cab temperature. But the blend doors do not go to neutral position when the engine is off during a start stop event. Starters aren't really that bad either. Like $125 for my truck. And I've rarely replaced any. Starters have come a long way. Batteries. Man we have been going through them.
@@BeardedFordTech yeah copy that, starter on my jeep just went out luckily at work lol. Great video thanks for the info.
@@daddydiesel5889 your very welcome.
Thanks! I’d worry that responsiveness off the line would be affected. Sitting at a light then the rush to get going. Seems a lot to ask of an engine that just cranked. Not just wear but hesitation.

Your very welcome.
I'm not a fan of Auto start/stop but be aware that disabling it with a trailer plug tester will also turn off other features. Parking assist and Cross Traffic Alert for example.
That is true. I know how to disable it without a computer. But I'm not saying on here. I'm not being g held responsible for that. But yes you are correct. Cause it thinks a trailer is connected.
Thx for doing this very helpful video. I would much rather hear advice from a experienced mechanic than a engineer.
💯💯 and thank you for watching.
I don't think anyone has said that the Stop Start uses more fuel people are saying that it does not save you fuel.
It does save fuel. Can't use fuel if it isn't sitting there idling. Engineering explained did an awesome video on how it does save fuel. A lot of people were also saying that it uses more fuel because you use a lot of fuel on start-up. Do that multiple times it uses more. But in reality, it's saving more than using cause it isn't sitting there idling wasting it. I get it. It's not for everyone. I don't always use mine either.
The Jeep Grand Cherokees have two batteries for this system. Oddly in my 2020 both batteries were under the passenger seat. On my 2022 (new body style) the big battery is under the driver seat and smaller battery under the passenger seat.
Yep. They use a separate battery for their system. A friend has a jeep compass. A 2020. Her battery is driver side front where a normal battery goes. The auto start battery is right in front of it. My mechanic who works with me now just game from Chrysler.
When I bought my first vehicle with the engine shut off ( 2024 ) I checked the battery first thing and it is reading a constant 13.8 volts even after driving all day . No worries !
What kind of brand new vehicle do you have?
Just like with diesel emissions ruining diesel engines, auto start/stop can't be good for a starter, we have two hybrids that use a huge electric motor to turn over the engine, not a puny starter. I would like to calculate the fuel savings based on starter cost.
More along the lines of engine wear compared to starter cost. Starter for thus truck is like $298. An engine cost like 5k. Check the video is the pinned comments about a used oil analysis using auto start stop.
Owned a 2017 GMC Acadia with auto stop. Could not disable. Very annoying. Pull in to park, engine shuts off. Put car into park, engine restarts. Turn off engine before exiting car, curse the idiot engineers at GMC. Final step, trade in car.
Their new ones has a button. I don'tike GM at all
ok, i agree with you: no harm to engine, starter, battery, and no fuel economy. but the car manufacturers are happy and epa is happy.
I guess
It might save gas in extended stopping conditions but around here most stops are at a stop sign just long enough to cause it to stop and restart in less than a couple seconds. Or when you park it stops and restarts when you put it in park. Even where it might save gas it won't pay for the added cost of the robust components necessary to make it work.
Yeah in areas where there's a lot of stop signs. Not worth it. If you have your foot on the brake and let up slightly it won't shut off when you put it in park. It's mainly for cities with no idle laws. That's basically why it was made.
Some systems don't even use the starter to restart the car. They use fuel/compression to bump start the engine.
Either way, the whole myth of these systems being "bad" are from "mechanics" that either aren't formally educated in automotive tech OR they are the atypical shade tree mechanic. Basically the type of guy/gal that'll say it's ok to run on just your alternator when your battery goes dead, to remove your thermostat to stop overheating, etc... While these things may have been widely accepted 30 years ago they do not apply anymore.
Exactly. I think BMW uses compression doesn't it? 100% correct. Backyard mechanics or people with no idea how the system operates. That's the first thing. Get familiar with how said system operates
@@BeardedFordTech I like to think of it as the difference between a "mechanic" and a "technician." Personally, I have an Associates in Automotive Technology. Formerly I was an ASE Master Tech but I let my certs lapse because I'm not in the field anymore. I now work for the railroad and don't really have a need to keep my ASE certs up to date lol. But even though I'm no longer an Auto Tech I still try to keep up with the industry. I love advancements like this, hybrid technology, alternative fuel sources, EVs, etc....
@wusaint yep. ASE master here. Ford master. And usually the people who comment aren't even mechanics. But they will sure chime in and tell you how wrong you are and thats not how it works. Gets annoying sometimes. You on the other hand have the training and knowledge. You like to know how things work. Which is fantastic!
@@BeardedFordTech well I tip my hat to you sir. While I miss working on cars, the railroad ultimately offered me more and was a TON more dependable that flat rate work. I used to work for Toyota and then Mitsubishi.
Did Ford send you to school for the Mach E and Lightning? If so, how was that?
@wusaint I'm not at a dealer anymore. No flate rate here. Took a better job as a fleet manager/master mechanic working on powerstoke diesels. Yes they did send me to those classes. And I hated them. So many problems with those vehicles.
Enjoyed the classroom session! Ty
Your welcome
Thanks for the info, very informative.
Your welcome.
Any engine is stressed the most when starting and stopping. The engine speed goes from operating to zero and conversely during start stop. This puts stress on all rotating components. The fact that start/stop is activated makes everything endure 10x more punch than previously.
The fact that everything is built more reliably should, likely make the engine more robust if you disable start/stop... :)
Ahh okay. Thanks for watching have a good day
I won’t buy a car with auto stop that can’t disabled. In minnesota we warm our cars up.
You can disable them if you know how. Want to know the quickest way to warm your car up. Start it let it come off high idle and drive. Not hard but just drive. The temp will come up quicker. If you just idle. It take 15-17 min to come up to temp. If you come off high idle and drive. It takes about 6 min. Ford boss me did a video on this.
Me and my buddy have identical cars. He used ISS, I almost never. His battery died at 3 years of age. Mine at 4,5 years. Trips, distance - all as Identical as you can get. We live close, work at the same place and drive road trips to the same destinations while on vacation. Default battery is like 35€ here, AGM battery 200€. While it is true that nothing else in the ISS related system died for over 200k miles, his head gasket blew as he likes to rev it hard right after the cold start and do 200+ on autobahns - nothing related to ISS. If you count the price of the battery vs the fuel saved, battery still outweighs the savings about four times over
True. But I haven't had a battery fail because of auto start stop. I've had them fail cause they are manufactured very cheap nowadays. And are only warrantied for like 3 years now.
@@BeardedFordTech I have AGM battery from the manufacturer. Since 2015 it still works. You know why ? First thing I do is to turn off this stupid piece of sh1t feature that is wearing out your starter and all the other systems are had to be designed to work without engine power.
i work as delivery man now, and i see many of my colleagues leave the cars idling on purpose. this is against the company policy, but they do it anyway and no one to tell them.
Lots of idling is bad. Very bad
I despise that start/stop system. I just bought a new Jeep Wrangler and installed an Auto Stop/Stop Eliminator out of WV. It costs only $100; took about 20 minutes to install, and is one of the best mods that I ever bought! No idiot trouble codes on the dash or anymore start/stop.
Apparently everyone complaining about it is jeep owners they use a little seperate baddtery. And that sucks you had to buy 100 eliminator when all you had to do was ask a technician to disable it. Soo there's that. I guess it's a jeep thing.
@@BeardedFordTech I just had the dealership program a 3rd key that was $85! So a tech isn't going to disable it for less than $100!
@AStanton1966 you got ripped on the key too. As long as you have two keys you could have done it. See. A little research goes a long way. And I'm sure he would have done it. Takes about 2 min to disable it. Unless its just a jeep thing.
@@BeardedFordTech Wow, you sound like a genius. Where's you book being sold so that I can buy a copy?
@@AStanton1966 you can't afford it. You spent it all on a key and a useless $100 eliminator. Until next time. Have a great day. 👍
I turn my start Stop off as soon as i get in my car its a pain in the arse
Okay. Check out the video in the pinned comments. It is your choice. Not telling everyone to use it. But turning it off may actually be causing engine wear. Check out the used oil analysis video in the pinned comments
I remember Porsche having 2 year service intervals on the 997's & they said it was totally fine, since then I just use my common sense & ignore 'Experts'. I've switched off my ss on my Golf R.
That's fine and dandy. It's not for everyone. I did a used oil analysis video using start stop. Might surprise you.
@@BeardedFordTech Very interesting & I appreciate you effort & sharing your findings. Personally I think it will depend on driving styles & conditions that will give different results. As we know fuel contamination will damage the engine over time if the oil is not changed regular & short trips is the main culprit. So if you are doing short trips your oil will not reach sufficient temp to evaporate the fuel & water so surely if you are using stop-start it will take even longer to get up to temp & allow even more fuel & water to develop?
@alliedfroth I did a used oil analysis using stop start. Check that one out. And yes it does depend on how you drive. But. If it's not on idling then it's not getting fuel dilution. Mine shuts off one time on the way to work. So I guess it depends on how far your job is and how your driving. So yes you are also correct
I have a '23 Corolla Cross; it all depends on your driving environment. In Cheyenne, WY, i was never stopped long enough to make use of the system. In Denver or Phoenix it's worth it.
Along with a switch to disable it, you have the option to opt into it by depressing the brake more firmly. If the battery needs charging or the cabin temp needs to be maintained, the system won't engage...and the driver's display will tell you why. A completely seamless operation on this vehicle.
Same with ford. Heating or cooling. Change in cab temp. Steering wheel turned. Defrost on. It won't shut off. It has its perks.
Modern vehicles now have a button that lets you deactivate the auto start/stop so basically the only time it's being counter intuitive is if you were in traffic, which then at that point, just deactivate it in traffic, which is probably why the button is put there now.
If you say so. Have a good day.
In our Mazda CX5 drove to the City, Brisbane Aust. The engine stopped and started 27 times. This has to apply wear to the starter, ring gear and battery. Have been a heavy equipment fitter for 50 years. I have seen plenty of damaged ring gears worn out starters. This is a sales gimick to sell cars.
🤷♂️👌
I am not a mechanic.........but logic tells you if you are doing dozens and dozens of extra start and stop cycles per week.........it has to cause damage to the engine and starter and battery. Come on it is a ridiculous idea and saves tiny amounts of fuel. Also the cars with large displacement engines have to use heavy heavy duty batteries. My next door neighbor has this feature and he had to buy a 350 dollar battery.
It wasn't his start stop that ruined the battery. Batteries are only good for about three years now. That's why they only have a 36 month warranty. And I've had brand new ones be bad. Saves a little more than a tiny amount. You know what ruins an engine. Lack of oil changes. You know when most wear occurs on an engine. First startup in the morning. Not stopping and starting all day. If that was the case. Everytime you ran errands somewhere multiple times a day then you would wear out your engine so quick. It doesn't work that way. The parts are built just a tad stronger. Will they fail? Of course they will. But if properly maintained. No sooner or later than any other part. Check out Engineering explained. He's a engineer and goes through great detail on the system. Learn about the system. I understand everyone has an opinion. And I'm not saying everyone should use it. Cool if you do coolif you don't. But people that blame the system cause their next door neighbors brother In law had a battery fail and said it was auto start stop. You ever hear the phrase. "You do 100 things right 1 person knows. You do 1 thing wrong everyone knows". Everyone is quick to spread the bad news and it may not be the whole story. Have a good night. I did a video on how the system actually works.
Auto start/stop frightened me plenty of time I hate it especially after I modified my exhaust 🤦🏾♂️
Up until now it still frightens me especially after a long day
They need to leave option so ones can use it or turn it off if we don't want it
You must have a Chevrolet? Cause ford you can turn it on or off. There's a button on the dash that allows you to do so. The only ones I've seen that won't let you or is no button is Chevrolet
@@BeardedFordTech i have a 22 GMC 1500 5.3 Elevation. Bigs cheers 🍻 to the Ford owners for having an option to turn on/off auto start/stop 👍
I can say, i always shut it off when i start my vehicle, saving the battery and starter from premature failure is a lot better than maybe saving a half gallon of fuel per full tank. On top of that, this guy being a supposed mechanic should know that start up is the hardest on an engine just because of the fact of no oil pressure.
Yes. Cold start is bad. My used oil analysis says otherwise about engine wear. And no it doesn't prematurely wear out the starter or battery. There is parameters it follows. Will those parts fail? Of course. But no sooner than any other one. Unless it was built with low quality.
@@BeardedFordTech False. I've replaced more starters on vehicles with less than 100k than I ever have before stop/start vehicles came about. Same with batteries. Not to mention now there is TWO batteries to worry about and when that aux battery burns out, it throws a code that keeps it from passing inspection.
You even mentioned the secondary battery. That secondary (aux) battery is not for starting the vehicle. It's to run all the accessories so your main battery doesn't get pulled down while sitting there.
@Charlie-dv7ev ford uses one battery. Dodge uses 2. There is literally ONE BATTERY in ford. You may have replaced starters. And it sounds like you work on dodge. Cause everyone one of those start stop systems suck on Chrysler.
It wears out your starter and battery point blank I've seen it time and time again oh it's also called wear and tear 😂😂
Of course it wears it out. But no sooner than a system without stop start. Do your research. I've worked on many vehicles with it. I've replaced one starter under warranty due to the starter having a broken solenoid. And one a couple years back on an impala with 130k miles. Other than that. Never had to replace it because "it wears out your starter and battery" it's just normal wear and tear. Batteries only last three years now anyway. Not the typical 5. Every battery you see now has a 3 year warranty. So your right but but also wrong. Even did a used oil analysis at 7250 miles to see what it does to the engine. Guess what. Engine wear went down. Starter and battery still good. Battery actually lasted 4 and a half years instead of 3. My Truck (and many others with it) still going strong. I see it looks like you a honda tech. Their stop start system along with dodge is garbage anyway. Maybe it wears out their starter and battery quicker.
I disconnected the start/stop feature instead of hitting the A button inside the vehicle every time i start it. I just find it annoying and you only save a few tablespoons of gas each full tank. The ONLY downside is a tiny lil light appears on the dash display, whooptie doo.
And that's totally okay. You actually save more fuel in the city commute. But. It also keeps your engine from wearing out. I did a used oil analysis using it. Go check it out if interested. It's the amsoil 7800 mile one.
In my opinion it’s more of a safety issue than anything. I had a Jeep Cherokee with the auto start stop and the safety issue I ran into was while in a turning lane. the engine would shut off and I wouldn’t have immediate power to make a turn over two lanes of traffic. I had to remember to make the car restart before I decided to turn. Other wise my timing to make the turn was off by a few seconds.
A few seconds? You do know that's a "jeep thing" right. Their stop start system is weird. It seems like it takes forever. We'll it's Chrysler so what you expect? Their start stop system is garbage in my opinion. Surprised you didn't get the recall notice they had to inspect the system.
@@BeardedFordTech it was a 2019 don’t know if it had a recall or not. But if I was too quick from engine off to on the accelerator it would either lurch forward or have very poor acceleration. It definitely put a bad taste in my mouth for the auto start stop tech. I test drove a ranger and didn’t feel like it was any better in that department. I just expect that when I hit the gas I have immediate acceleration without hesitation or lurching.
@captnMorgan41424 that is with all vehicles. There is a delay on acceleration from a stop that is programmed into the pcm. That's not the auto start stop. My ranger does lunge forward. Doesn't take seconds to start its instant. Haven't had any problems with it. There's a worker here that has a 2020 jeep. Hers does it too. Their electrical systems are designed by fiat. Or were so that could still be the issue. Could also be the programming parameters they use for the system. You aren't the only one with or had a jeep that does that. And a lot of people hate start stop because of that. Or they don't completely understand how the system works. I get it I really do. I wonder if jeep/dodge has fixed this issue. Curious now.
The starter and battery may be beefier, but are A LOT more expensive to replace. Gas savings gone. Your battery dies in a normal car in your driveway or at work a small hassle. An idle stop dies in rush hour on the freeway with the kids or grandchildren in the back seat....
A battery is like $200. A starter is like $200 (for this vehicle) now. What wears out an engine? Idling in traffic. That's called fuel dilution. The number one killer of oil. So. $400 compared to 6k for an engine. Do the math. Or even check out th used oil analysis video I did using stop start. Not saying you have to use it. But usually if there is a problem with the system it won't shut off in traffic. If it does and there is a problem then you might want to find out what that underlying problem is. I did a video of how it operates. What it looks for and what parameters have to be met for it to shut off.
Does it mean that I cannot replace my battery by myself because the system must be reset and most likely be done by a tech with fancy diagnostics? How is that an improvement??! Or I have to start buying more expensive battery because of this start-stop system! Ridiculous. What if I don’t care about gas mileage?
This technological complexity is nothing but a burden on consumers.
If it's a ford you don't need a scan tool to reset the battery monitor system. Three ways to do it. A. With a scan tool. B. Let it sit for 8 hours after replacing and don't touch anything not even the key. C. Key on. Flash the high beams 5 times and step on the brake 3 times. Battery light will flash after about 10 sec to indicate it has been reset. The technological Complexity is apparently what consumers are wanting. Not all but most. And it can be a pain to work on trust me. They should have more options for people who don't want this stuff. It's also EPA involved in all this stuff.
I have a 2021 Honda Accord. And a few times I've turned of the engine idle stop system, but I usually don't turn it off. And so far so good. You think Honda makes a good start/stop system?
Never been in a Honda that had it. Couldn't tell you. I know dodge and Chevrolet systems aren't great at all. Slow to crank. Go check out my 7,000 mile oil change video.
Like with all new tech It will be hella expensive to repair when it does break down, and you bet your A.S.S. it will.
248 dollar starter. Not too bad. Of course it will break down. Better than a 40k battery on a tesla.
Start stop is aggravating when you're trying to pull out in traffic and you have a 2 second delay.
Ummm. Why would you pull out in traffic? 🤦♂️ You do know if you turn the wheel itnwont shut off right
If you drive a late model car with S/Stop function, don't stomp on your brakes and the engine wont switch off... soft braking is the way to go, I do this every day, and hardly ever have the engine turn off... but of course you will hit the brakes hard if an emergency crops up... but it all comes down to the way you drive... there are people who just drive, and there are drivers who understand their cars.
Finally someone gets it. It's all on how you drive!
Only good when waiting in a chick fila line on a Saturday
That would be the same as sitting at a red light or in a traffic jam. Two questions. Your chic fila that slow? And who actually goes through a drive through? Our chic fila here is on point. Even though I never go through the drive through. But the time I get my food the car I saw as I was walking in is going past the window with food. McDonald's I could understand.
I am going to disagree with you on your starter comment.
I live three miles from the nearest hardware store. I get in my car, out in my driveway, and start my car then I drive to that hardware store and park in their parking lot. That's one start. I buy some item at the hardware store, get in my car in their parking lot, start my vehicle and drive home. Shut my car off in my driveway and go in my house. That's a second start. So I drove six miles round trip and started my car twice.
Now, if I had auto start/stop my vehicle might go through a number of starts an order of magnitude greater than two. This is because between my house and that hardware store there are six traffic lights. If my car only restarts once at each light it is now starting a minimum of fourteen times if I stop/start at each and every light, and there are times when I do catch them all. Now, let's say that after stopping at a light, the traffic in front of me rolls up, and comes to a stop, and I do the same. Now my car is starting two times at that light. So it is conceivable that my starter will engage 20 or more times in that 6 mile round trip. And that is just a short run to the nearest hardware store.
Now, let's say I have to drive 40 minutes across town, about 22 miles. Which I do almost every day. On my most common daily commute I am hitting 15 lights, and that is with a 6 mile run on the highway. If, let's say, there is a wreck on the highway and I avoid the highway altogether I will encounter about 30 traffic lights. If I stop/start once at each light my starter my engage 60 or more times, instead of two, in that 44 mile round trip. You can't tell me that my starter won't wear out any more quickly if I engage it 60 times a day than if I only engaged it two times a day. SMH. No Sir, the math won't support your argument.
Now, I have a neighbor down at the end of the cul-de-sac who complained to me that he has been replacing his starter two times a year for the last three years. His vehicle has auto stop/start. It's three years old. My car is 15 years old and I am the original owner. I haven't replaced my starter yet at all. It still has the original factory starter. So my neighbor, by his account, is on his sixth starter in three years. I am still on my first after 15 years. So...🤷, seems obvious to me that we're observing cause and effect.
Something is seriously going on with your neighbors vehicle if he has replaced it that many times. I could understand if it was a dodge cause their stop stop is horrible or Subaru which is worse. Now. Back to your scenario. I see what your saying I really do. But you have to understand how it works. It doesn't shut off at every light say stop and go traffic for a few reasons. Reason one. The speed from your last stop to the next stop was not greater than 15mph. Reason 2. The time between stops was too short. Say you go 6 blocks and there are 6 stop lights and you never got over 15 mpg and are just creeping cause traffic is bad. The time between stops and speed should not allow it to stop unless all parameters are met. It's called a cool "cool down phase" between stops. So it's not or shouldn't stop 20 30 40 50 or 60 times. Most systems are designed to operate the same way. Your neighbors starter should not be going out like that. I've replaced one starter under warranty and it wasn't the stop system. It was literally the wire on the starter. Will they go bad? of course they will. But it shouldn't go bad that quick. Did they check other parts of the system that make it work? I'm not saying people have to use it or should. Entirely up to them. But I work on these for a living. I know how the system works. Not because someone's starter went bad up the street they blame the syart stop system without knowing the full details. How does that saying go? You can do a million good things and nobody will know. You do one bad thing and thr whole world knows. Same for the start stop.
Got a new 2020 Malibu LT and my main gripe with the feature is it makes me feel like my car is a bucket stopping at lights. I feel like everyone is looking like who is that guy in the terrible running new car? 😂
🤣🤣 I don't think there is a button to turn it off on Chevrolet.
@@BeardedFordTech yes there is. You just gotta remember to press it.
@TheMaddBlackMan last Malibu I was in which was 3 years ago (wasn't a 2020 model though) didn't have the button or least I couldn't find it. Wasn't really looking either
Small correction: an AGM battery is still a lead-acid battery. It just has glass fiber mats between the positive and negative plates, which increases its lifespan.
Yep. I know. Absorbent Glass Mat. Anything that has auto start stop has an agm battery. Only difference is its sealed. You can't add distilled water like the normal acid filled ones.
A dealer recently loaned me a brand new turbo hybrid with start stop. In traffic, there was just too much going on, and it was very herky-jerky. The engine would start, stop, the vehicle would accelerate on the electric motor, then the engine would kick in, then the turbo, all the time the automatic transmission is trying to figure out what to do. it was very herky-jerky. Some of the car magazines noticed the same thing. The transmission and the hybrid and the start stop just weren’t programmed well together. Probably a software fix but one that needs to be made.
That's also due to it being a loaner. The transmission learns how you drive. So how many other people drove it has to be taken into consideration. Nobody drives the same. Say you let me borrow your truck for a month. It will learn how I drive. When I give it back it's going to feel very weird to you until it learns you all over again. Must have been the f150 powerboost. Twin turbo hybrid.
Good to know, but this thing was brand new. 8 miles on the clock when I picked it up. Perhaps it would have smoothed out over time as it learned. Thanks for the reply!
@glenwoodriverresidentsgrou136 yeah it hasn't even been driven enough. It's brand spanking new. It takes a little time for it to learn. When it was built, there is a strategy in the solenoid body. It learns over time. Brand new ones we took off the truck to PDI felt funny too.
