😂have the same fillings about all that has been said about entire process, that user goes through, after battery dies. Our died after 2 weeks. The only thing we didn’t do is give the car to the dealer. Cause every time it’s US $180 for check up(if not a warranty case, after diagnosis) We drove around for few days, check engine light cleared. Yep, reading manual was helpful too. Also what was interesting is to revive a call from a dealer out of state, we’re we got a car, that they were notified in the system that the check engine light is on and we may need to visit 😅
Interesting. In Canada, they don't charge for the check up. I got it checked out and tested to ensure it's all good.
Very interesting, thank you for passing this on I'm sure it will be of help to many owners.Take note Paul.
Glad it was helpful!
Great video - just had the issue returning from a 5 day trip at airport. Will use your tips as i think this will help! Thanks!
You should look at my newer video on the observation of the 12V battery. That should help you understand more on the 12V battery.
Ah. Sorry to hear that thanks for the update. Glad to know that this is a widespread problem. I had the problem at about 6 months in and it has since died 4 or so times and i broke down and got a 12 battery charger maintainer, had it happen once since then.
How much do you drive? Surprised that it died so many times. Did the dealer check the battery and it's not a defective battery?
@@lsft 1 to 2 time a week typically like you I'm currently working remote. Dealer looked at it a couple times they blamed it on the dash cam and swapped it out, but still had issues so I ended up getting a battery maintainer/ charger and a battery jump starter. A bit unfortunate as I love the car but this makes the car a bit unreliable. Think about a solar battery maintainer and/or swapping for a more powerful battery. Of note I live in a very mild temps area, no freezing temp usually nice weather, low 40 to 90 typically 100+ a few weeks in the summer.
Hi LSFT, sorry that this happened... I sympathise with you. And thank you for informing your followers in details. On my side, the weather conditions are much milder as the ones you have in Canada. So, no need to drive when I can walk for 600m, and the batteries are not forced to operate under "extreme" temperatures. Hence, I am ignorant of this kind of problems... Thanks for teaching !
Jean-Marc, no need to be sorry - you being very Canadian here 😆. I'm just lazy to drive the 600m drive, the biggest issue is to go with my gym bag and walk the distance. Some times I would drive around the neighbourhood so it can run a tad longer and use remote start so that it would start and operate a bit longer to allow it to charge the 12V a bit longer.
This was very valuable information, especially the note on AC charging draining the battery. I have had Toytota plug ins sice 2005 and twice the 12V battery has died, and it is always when it is cold and always the battery hadto be replaced This makes me think to have battery tender installed on the NX which I oreordered.
Do you drive short distances as well? cold weather tend to drop the voltage and cause a 50% charged battery drop to a point where it cannot start the vehicle. I think a battery tender is worth the money. I just wish to have it installed so that it can be easily plugged into or Toyota/Lexus should just update their system so that when charging the traction battery, it would fully charge the 12V battery as well. That way it shouldn't be a problem at all.
Very helpful, thx
My pleasure
Another issue that can drain the 12V battery is if your dashcam is not set to the correct low voltage cutoff levels. Many newer dashcams have presets specifically for hybrid vehicle batteries.
My dashcam that is live is the Lexus Genuine Dashcam so that shouldn't be a problem. But definitely a good tip for other dashcams with parking mode
As I also work from home so I dont daily drive, I occasionally go for vacations for almost a month, and winters are cold in Alberta, I got the dealer to install the built in trickle charger on my Lexus UX. The lexus / Toyota ones are so nice imo as you never have to have a cable sticking out. Knock on wood, nothing bad as happened yet so I think its working well. I only plug it in on the colder times and I have stopped now since its much warmer. However I will be on vacation soon so I will be plugging it back in then.
That's great. It's more integrated with the Lexus Toyota one for sure. Not driving frequently is actually better than just driving 600m per drive. 😝
Hi, must say the battery tender route is a must when you do small mileage in a cold climate. For me since retiring all my vehicles are on C-Tek battery tenders, until I require them. Thank you.
Yup. Totally agree. The work from home has changed my driving habits.
What is a battery c-tek?
@@jackibagbaga7638 Hello Jack It's basically a intelligent battery trickle charger that maintains your battery at it's optimum level of charge. If you use your car infrequently especially during winter months, if you hook up a battery maintainer it will keep your battery in perfect condition for when you require your car or motorbike.
The same thing happened to my NX450h+. I let my sister drive to the mountains. It was snowing and super cold. Her boyfriend was not feeling well at the part they went to. So he went inside the car and decided to take a nap for a few hours. The next day the car would not open. I believed that maybe he had started the car without pressing the brake pedal and the traction battery had zero miles. So the next day they asked for a jump start.
So, maybe what happened was the 12 volt battery depleted after he went back to the party because of how cold it was.
I don't have a place for a trickle charger, I don't have a garage or drive way, to prevent this from happening. But then again I live in LA and the lowest temperatures here are 7 or 5 Celsius. So maybe when we go to the mountains I have to take a jumper just in case
Well, if he had not started the car and 2 hours of accessory mode - it won't drain the battery. Leaving a light on for 20 minutes it will turn off to save power, but in accessory mode it will not power off and will drain the battery. Like me driving very short distances would do the same no matter it is an ICE vehicle or PHEV. I really hope Lexus introduces some features that will detect low capacity and auto start the car with the traction battery to recharge the 12V. Or fully charge the 12V with the DC to DC charger while charging. I believe Hyundai has a button in the car to tell the car to charge the 12V from the traction/hybrid battery.
@@lsft oh!!! So it was the battery running low without warning! Because of the weather?
I had similar issue. Thankfully I had my Aukey booster. I popped the hood, there is a plus red connector under fuse box cover. I attached booster plus to that connector and booster mints to a bolt threaded to the body. Few seconds later my car was up and running.
My Noco booster was not enough to boost the car up. It could be related the booster was not fully charged.
@@lsft Mine is similar to yours. And, yes I charged it fully. Also, it’s not a good idea to boost from battery terminals.
@@lsft Also, quick tip. Keep the booster somewhere under the seat or glove box … within reach. Otherwise, when the car is dead it’s extremely difficult to get the booster from the trunk.
@@GenaMak true when battery dies cannot open rear door to access battery; there should some way to manually open rear door; what a design!
@LSFT for information in France we have a recall on DCM communication module that can in certain circonstances drain the battery. I will not wait for my 1 year service to have this check if this problem can be a root cause of battery dry. As far as i understand, and you will probably confirm, as soon as we put ignition and system is in "Ready" mode, the system begins to charge the 12V battery. In that case if you do only very short trip, and as you have a garage, maybe it will be good 1 day per week, to keep the system in ready mode for 1h approx. This will allow the high voltage battery to charge the 12V battery through the DC/DC converter. In EV mode, A/C off, engine will not turn on.
What is not normal is that it is recommanded to unplug as soon as charge is finished. Because when doing during the night, you are not going to wake up or monitor car charging to see when it is in 100%. If this scenario was draining the battery, it's up to developpement team to fix this issue, simply by having a software that monitor the 12V battery condition, and activate the DC/DC converter to recharge it as soon as needed.
This is a quite annoying problem, because i buy a PHEV for my very short daily home to work travel and i do not choose the HEV to avoid engine start / stop working only in cold condition.
But from time to time i have a very long trip.
You are correct. If you start the vehicle it will start charging the 12V battery. I will show more details in my next video when I install the trickle charger. The car will actually power off if you keep it running for 1 hour. It has a system to ask if you want to turn it off after an hour. That could be one option to keep the battery charged. As long as you do not need that range the same day. But really, having the car run one hour may not eat too much into the range.
Well, typically if you set it to charge up with the destination time, you won't need to keep it plugged in for too long. I typically now will plug it in around 7pm install of having it plugged in from 8am until it should start charging. That way it's not plugged in running for 12 hours before it starts charging. I always set it to charge up to the time I depart, unless it's like I go home to fully charge and start it immediately. So when it's done, I would go out and unplug it. I don't think you need to be that precise on unplugging it.
I have my 2024 lexus nx350h luxury; owned it for 4 months and 3500 miles. yes the car will not start twice i since i owned it. the latest incident was scary because i was locked inside the car with all windows fully closed and didn't know how to get out. i had a short orientation on how to operate but never had an EV or hybrid car before so when lock inside and cannot get out i panicked, had shortness of breath, phone went dead after been using it to reset pin in lexus app. i could have died but luckily it happen inside my garage and just had little charge to call my wife before it went total dead. she came out out and panicked too even with card key and extra FOB key. i was able to instruct her to use the manual key but still wouldn't open after inserting the manual key; even i was trying my best to open from the inside for almost 20 minutes. she called 911 thinking maybe fire dept can jump the battery in case it's a dead battery. while fumbling everything inside including lexus overhead red emergency button, i was able open maybe it was a lever i was suppose to pull; i had been pushing the door unlock button the whole time. i was worried i was going to go unconscious if nothing works. later my wife said the last resort would have been to break the window of a brand new car over 70k car(58+10% tax+4500 prepaid maintenance+ 2500 cilajet coating by dealer+2000 frontal PPF) . i'm worried that if i have my daughter to come drive while i and wife out on three month out of the country vacation and this happens; i told her to come and drive it at least once a week. i wonder what the dealer will do because this is the second time it wouldn't start. last time a tint shop jump started it but they were not lock-inside unlike me. check engine light came on after they jump started. i drove to another city lexus dealer where i bought but then lexus said nothing to diagnose because the check engine light disappeared. after hours so can't get any help from dealership or lexus headquarter.
Looks like your 12V battery died while you were trying to reset the pin on the Lexus app and the Lexus Interface. It's important that the dealership should have showed you how to manually open the door when the car battery is died. You pull the lever twice to open the door when there is no power. It's actually easier to open from the inside than from the outside. If it is already unlocked, you pull the lever under the handle to manually open the door. If it's locked, then you need to pop open the cover and use the manual key to unlock the door and then use the same lever under the handle to open the door.
Whenever you let the car idle, you should keep the car running in "ready" mode to ensure the 12V does not drain causing the door handles and all electronics to stop working. Typically when the engine light turns on during a battery drain, it could be related to the seat or some other functions stop working causing the engine light to turn on. If the light is off, it's because the accessories are working properly and the codes are off. It does feel that the 12V battery was drained - similar to the issue I had in this video.
@@lsft i called the lexus road assistance and they did a booster charge; he said remaining voltage was so low 2 volts. It is half a day of my time to drive it 40 miles to dealer. We'll see what the engine lights says tomorrow when they check it out.
@@jackibagbaga7638 keep me posted. They could try to charge up the battery and do a load test. If the load test fails, they will replace the 12V battery or if the load test is ok, then they will just clear the codes and return the car back to you. Just make sure you keep the car in ready mode when you do anything. Don't stay in accessory mode. Also, if you drive short distances, you may need to consider a trickle charger to maintain the car battery. If you don't drive enough, over time the 12V battery will lose capacity causing a dead battery.
Several years ago we had a battery failure on our BMWX3. Our road service technician told us that we should always lock our car in the garage because there are several systems that continue to run and drain the battery if you don’t lock the car. This excessive draining reduces the life of the battery. I am amazed at how many systems the 450 has running and the above advice is even more important for this car. Going to France from Australia for 48 days next month, I assumed the idea was to leave the charging cable connected. I now see that the opposite is true. Surprisingly, Lexus will collect my car at the airport, store it, clean it and return it to me 48 days later at the hotel we are booked into due to a midnight arrival home. Free of charge.
Having had our 450 for exactly one week, we have done 330km and have enjoyed it. It will be much more enjoyable when Lexus installs our fast charger on Monday. How about some videos on:
A. The ratio of km using battery to km using petrol and the cost per km saving in cents. Yes, that will be different for each user. I note that you are spread sheet literate so you could have some fun with this. I have created my own spread sheet and have reached a number of 9.26 cents per km based on my current situation. With the addition of more batteries for my solar system in June, I expect the saving to increase and help pay for the batteries,
B. How to managethe life of fuel in the tank where burning petrol is very slow. I can imagine not using a tank of petrol in 4 months. What is the problem if any? Is there an additive that I can put in the tank to maintain the volotile portion of the fuel?
Thanks for the video ideas. I actually park my car in the garage and it's locked. I have a habit of locking the car no matter where I park. That's great you have Lexus storing your car while you are away! Great customer experience.
It's pretty simple, when it's below -15c always drive your car until it's fully warmed up, force the engine on and heat it. Drive it like it's a straight ICE . Drive it long enough to warm the fluids to normal operating temps
The engine was on the night before and it was totally warmed up. It's not that simple with the PHEV. Even with remote start the engine have already warmed up and the cabin was warm as well. It's really the prolong battery drain and causing the 12V to be low in capacity. It was able to start on the coldest day of the year. It just died the day after.
Sorry this happened to you, while I do miss the snow and hometown of Vancouver, I don’t miss the early morning snow ploughing, because Australia never goes under zero😂
You being very Canadian. No need to be sorry @Siquan. Vancouver don't get that much snow. 😂
@@lsft that’s why I could never live in places like Edmonton or Montreal 😂 I got frozen physically at -15c 🥶 not very Canadian at all
Thanks for sharing this video. I still don't quite get where the battery is drained, you were driving short distances sure, but that same day you drove another 15mins+15mins, wouldn't that be enough to charge the 12v battery?
Also I was tempted to get a smart plug for the garage outlet that's to charge the car, when charging is completed and current is dropped for some time turn off the power, not sure if this would help
Hey Paul. I think it's prolong driving short distances over time will drain the battery to 50% capacity causing it to drop further when it got cold. The system may not have charging enough of the 12V battery when it was -21 causing it to not have enough juice to startup. You know the NX startup uses a fair amount of electricity from the 12V, where the headlights are on, the seats need to move forward, the systems are booting up. I think the smart plug would need to be able to handle the current and not cause issues to the EVSE, but that could be an option. As long as the car doesn't think that the charger is still plugged in.
@@lsft that makes sense, so you may not be charging the car often enough during those days? The charger connected part is what I'm concerned about, like you show in the video, if charger is "connected" then it would drain battery, not sure what's the case when outlet power is cut off but charger still connected. For the current, most smart plug is rated 15A so I guess it should be fine
I have an NX350h Executive and had the battery die shortly after taking ownership. We took possession in November 2022 and had driven a few trips that amounted to about 15-20 kms each trip. As it's a hybrid the gas engine cycles on frequently even around town, once you go over about 35 km/hr typically the ice will start up. So you would expect the 12 volt battery to recharge during every trip. I have 2 dogs so I had bought new back seat cover and door guards (didn't want to experience dog toenails scratching the wood inserts in the doors 😫). I knew that doing the install the doors needed to be open for a while well I figured out how to install everything correctly so I turned off the interior dome lights. Didn't help much as after I was done, which took maybe half an hour the car had drained the 12 battery down and nothing would work. Luckily I hadn't locked and left the car so the doors were open and I could get to hood latch to open it. I knew I had the Safety Connect Service I could summon using the Emergency Assistance Button ([SOS]) via the button located on roof by the interior light switches but as the battery had died, guess what it wouldn't connect!! So keep in mind you may not be able to summon a tow truck or have some fuel delivered etc if your battery dies you better have a charged cell phone handy to call for assistance!
So I called Lexus to have them boost the car since it was only a few weeks old and didn't want the hassle of possibly having not jumped the battery correctly (please read your manual to learn how to do this correctly as the battery is in trunk and not under the hood! You need to know where your contact points are to jump start battery correctly). Tow truck arrived within minutes to boost me and went on his way. Dealership called next day as they had been alerted by vehicle that there was a dead battery situation. Had the annoying fault warning constantly show up on centre display for a couple of trips then it cleared. Bought a new NOCO GBX45 and extension cables so that you can connect booster while in trunk with battery directly. Keep the booster charged up, says a full charge should last up to 1 year. The battery label looks like the 350h has a 563 CCA (cold cranking amps) which should be fine. My 2009 Murano takes a 640 CCA battery and that's to actually start a V6 engine and my battery lasts 5-6 years typically and I can have the doors open and interior lights on for quite a while too and still start no problem.
When you consider the time I took was probably about the same time it would take to open up the doors to clean the interior. So the usual open doors remove mats vacuum interior etc. And then your battery is dead! I'm not sure but maybe because I had the key fob in my pocket the car might have turned on daytime running lights or the parking lights I never checked but that would help drain battery too.
Learned that both 450h+ and 350h don't actually have a physical starter motor like typical ice do. One of the electric motors connected directly to the crankshaft actually spins up the gas engine when called upon to start. Hence why the startup of the engine is quick and quiet and doesn't shake the car when doing so. But the 12 volt battery does all the work in the background even when you're not in car. So all the communication with Lexus app / digital key on your phone, cellphone network for maps, software updates and security tracking system, looking for your key fob constantly while your close by so that it will unlock as you approach it etc etc. All of this drains the 12 volt battery on an ongoing basis. Note you can reduce your cell phones digital key range on the app to nearby so that your car won't try to connect to your phone while it see's it when you're inside your home constantly. This will keep your 12 volt battery from draining as well. I also keep all my key fobs key cards in a faraday pouch as well so their signals don't reach the car and also for security reasons no one can boost key signal from outside and start vehicle and steal it!
Thanks for the detail explanation on your situation. The 350h has 563 CCA which is more than what is in the 450h+ There is only 325 CCA rating battery. I have turned off the digital key on my car. The car should auto power off the lights after 20 mins of being on. It shouldn't stay on even if you have the door open. That is to reduce battery drain from the 12V. It's possible that your original battery did not get charged after it arrived to the dealership as that was suppose to be a pre-delivery step. You have to keep in mind that the car goes on the ship for many weeks before it arrives our shores and they would need to charge it before delivering it to the customer. You could boost your car from the hood in the fuse box. You don't need to crawl to the back to do that - Lexus has already created an extension to the hood so that you can boost from the front.
@@lsft Yes as mine is a 350h it was made in Cambridge Ontario and it was built on Aug 2022 but waited at factory until November for stereo amplifier components to arrive on back order. We had taken the car for a good 150 km drive when we picked it up so was hoping that would recharge both batteries. I see that for the 350h you can now purchase from Lexus a battery tender for around $500 installed under the hood. As I had the Lexus block heater installed at dealer before I picked it up I can use the plug in found on lower front grill to also power up the battery tender. I think I’m going to get that installed soon to make things neat and easy to use. I don’t do much driving presently maybe 15,000 kms. Year so battery drain concerns me. Thanks for the reply.
@@re-tiredsteve5195 You can install the battery tender and it will be able to charge from the grill. But you could boost from under the hood as well. No need to go to the back. You actually drive more than I do. I'm almost at 1 year and just past 10k.
If the battery is in the trunk, how do you open the trunk when the 12v battery is dead?
@@rainingintokyo Good question! On top of that the 4 entry doors are opened with an electric switch too!
You need to open the drivers door with the mechanical key feature, see the owners manual for that. Once inside the car you open the hood latch and raise the hood. Also in the manual, you will find there is a location inside the fuse panel located near the top strut mount on drivers side, that has a flip up cover and inside is a positive + connection point for jumper cables that connect to the battery in the back. The negative - cable would be connected to a bare metal feature nearby. I've used one of the bolts for the strut assembly as it's nearby. Now with a known good battery connected on the other end of the jumper cables you can boost the car and the back door will open. Please keep in mind that you should familiarize yourself with the jumping / boosting procedure in the owners manual to make sure everything is followed correctly to prevent damage.
this is interesting, thanks for informing us. I have a quick question, do you garage your vehicle or is it stored in the open? I really enjoy your videos, I am waiting for delivery of my 450h+, just on 12 months now since ordered.
I park my car in the garage. Rarely it's out on the driveway
i ordered mine May 22' . expected delivery......May...... 2 0 2 5 !!!🤣🤣🤣

I can’t start my 2024 NX450h+ on the 4th day after I own the newly bought car. Went to the dealership and they couldn’t figure out what’s going on. I can’t start again after 4 months and this time they change the 12 volt battery for me. Still can’t figure out what’s going on. I left the charger plugged in for a few days after fully charging it. I guess that’s the issue after watching your video.
That's definitely one of the issues. I do have another video talking about my observations of how the car charges the 12V battery.
Sorry for the random question but how is the noise of the NX450h+? I'm getting used to it now, but was surprised how loud the 2023 Rav 4 Prime XSE PP was on the highway. Is the NX450h+ better?
I never drove the RAV4 Prime, but some NX450h+ owners had owned the Prime before and did say that the NX is much quieter. The insulation of the NX is better, but the gas engine when pushed will be noisy as well. However, if you are driving within the Eco range of the hybrid meter, it's very quiet. EV mode it's quiet, but definitely not the quietest Lexus.
So let me get this straight. The only time the 12v battery is charged by the traction battery is when the ignition is on or the traction battery is being charged. Otherwise the 12v battery is on its own. Is that correct?
You are correct. I heard that when the car is charging it would also charge the 12V, but after charging is completed it will stop charging the 12V.
Mine is the combustion 350 f sport….so i guess being an electric holdout might make some sense right now…hybrid or ev
It would be the same problem if I drive short distances with 350 F-Sport. The 12V battery would still be a problem. So it's not because it's a PHEV or Hybrid or ICE vehicle.
@@lsft right….you’re in canananada 😊
@@your_royal_highness 🤣🤣🇨🇦🇨🇦
that doesn't make a lot of sense to me, to be fair.
why can't it charge both batteries when it's plugged in?
I don't think that operating dc-dc converter should be limited to just driving modes.
I mean, ok, normally when not driving, high voltage battery is disconnected - that part I get.
But when charging, I believe it is connected, so why don't charge the small one too?
do you have any ideas to why is that?
I don't have much details on it. I read somewhere it does charge the 12V battery, but I can't confirm that.
My car 11 yrs hybrid 450h has just start not starting. I’ve had it at the dealers twice and they said there’s no problem(!) they disconnected my dash cam completely and the battery is only 12 mnths old , a Lexus battery and is reading ok. The problem I have is it kicks over to show the initial start up lights but then doesn’t go onto “ ready” or engine doesn’t kick in. It’s intermittent and not predicable either. I have been caught three times in car parks late at night ( RN) with it not starting then after a while it will. So frustrating NRMA said it might be the brake light switch and to really pulp the brake pedal hard next time it happens.
Any comments welcomed 🙏
Ps driving this in Australia so weather extremes not a real issue
Most likely you own a RX450h. Definitely something is draining your 12V battery. Do you drive it often or does it sit in the garage a lot?
@@lsfthi it is a RX 450h 2013 model. I drive it around 50-100 klms per week. Disconnected rhe dash cam. The prob is that it’s so unpredictable when it’s going to break down. Ie will start every time for 2-3 weeks then next week might not start a couple of times. All Lexus will say is the computer says there’s nothing wrong with it. But they aren’t the ones stuck in a hospital car park at midnight. Thnx for ur response appreciate it
So just got my brand new Lexus RX450H+ less than 2 weeks ago and driven it about every third day or so. And today, 12V battery is dead. Can’t start car. Tried following steps in manual to charge the 12V battery with jumper cables attached to front designated area (Positive terminal next to fuse box and negative on metal clip).
Weird thing is whenever I connect all terminals to the other car’s battery, the alarm goes off on the Lexus. Have you experienced this when trying recharge the 12V using jumpers from another car battery?
Yes that is noted in the manual that the alarm could go off when charging under the hood. I typically trickle charge from the trunk instead.
@@lsft Didn’t have any power to open trunk. But figured it out. Right at moment hooked up the jumper cables, clicked the Unlocked button on key fob to disengage alarm.
If the battery is in the trunk, how do you open the trunk when the 12v battery is dead?
I get it from the back door. Make the back seat flat and climb in
I am actually shocked that Lexus has dropped the ball on a one year old Lexus NX this could jeopardize the reliability matter. or onwers of PHEV just have to more technical mined.
I think if you drive longer distances it will less likely have this issue. I have drained my CT when I had 1 car while waiting for the NXh+. So driving short distances definitely does not help the health of the 12V battery.
-21 celsius is not “cold”. I live in Alberta and drive my auto in temps of -30 celsius or colder every winter. I’ve been considering this suv and hearing this has me wondering if it’s a good car.
The reality is - if I drive any car with such short distances the 12V battery will drain and not charge enough. Pre-pandemic, I would go to the gym and then go to work this would never be an issue. This is related to my driving behaviour over an issue with the car. I don't think you need to be concerned.
Well, I can't compare "cold" when it comes to Alberta or Yellowknife where temperatures can go even colder, but -21 for many of my viewers is COLD. 😆
From the system design point of view, the car should have programmed warned you before the 12v dropping too low. It is more of a design issue than really your fault. Don’t blame yourself, even I agreed Lexus has been good.
@@wickytam2006 I hope those features could be added as an OTA. I feel that we shouldn't even need to worry about it. The car should just wake up and recharge from the traction battery.
@@lsft agreed 100%
I've been an owner of a Lexus Hybrid RX for 14 years and I'm fully aware of this behaviour. If the vehicle's 12V battery is dead, you'll get the Check Engine warning alert on the instrument clusters. My advice is to have a portable battery jump starter to get you out of troubles. This is also an early warning that your 12V battery needs replacement. A NEW 12V battery should keep you happy motoring for the next 5 years.
The car is less than 1 year old. The cause is driving short distances. There is a common trend of me PHEV owners having dead 12V batteries within the first year of ownership.
@@lsft Then I would plug the 12V battery to a trickle charger overnight to keep it in top shape. I don't live in sub zero temp so I can imagine your vehicle would require more manual intervention. I highly recommend the CTEK MXS 5.0 battery charger.
@@chat2stephen thanks for your info. I do it once every few weeks. Seems to be ok.
The picture of the battery under the hood is not a 450h+, my battery is in the cargo area.
That's stock photo for the trickle charger/booster. Yes the battery is in the cargo area. I have a few videos showing the battery in the cargo area. You can boost the car from under the hood.
@@lsft I have the Executive Package, just over 12 months old, 8200 kms, filled it 5 times, total 185 litres, battery dead in Nov, called Lexus roadside, got boost, next day took to dealership, found nothing, no codes, dead again in Feb, same story can't find anything wrong, was told to drive it once a week for 20 minutes or put a trickle charger on it. The car other wise is great ( price of nearly $80000 is way too high.but I paid it.
Is there a way to reset the CEL after dead battery? Without having to go to dealer?
I went to the dealership to get it cleared. You can try to drive it for a few days to see if the light disappears. I used an Obd software and turned off the engine light, but there were still messages on the infotainment
@lsft After charging 12v battery and a few drives, the error went away.
@@longle7603 good to know
Does anyone know if this is also happening to the annex 350 H?
If you drive longer distances it shouldn't be a problem. You don't need to plug in and have the 12V to monitor the charging - so the likelihood is going to be much less.
@@lsft thank you
Do you think the Lexus folks at the top know this problem so they can fix it in the future?
I think they are aware of it and not sure how and when they will address it.
More Techs more problems
That's cars nowadays
I had a 2022 450h+ Fsport and a 2023 450h+ Luxury and after a year with both I HATED THEM… I can’t believe this Japanese people claim this SUV Fsport is ‘’Sport’’ SUV when in fact is FAR FAR FOR BEING ONE AND EVEN FAR OF LOOKING LIKE ONE….
I sold them and now I have a REAL SPORT SUV with the Porsche Macan for the exact same price!!!
I will NEVER NEVER WILL GO BACK TO LEXUS, I hate the Sound system, the skinny tires , uncomfortable seats…
The NX and RX are a scam….
Keep in mind this is not an NX F. It's only 450h+ FSport Handling. Not an F SUV. Anyways, if you don't value the Lexus experience, then go to another brand. Nobody forced you into getting a Lexus. I don't think they mind you moving on to another brand. Seems like you are enjoying the Porsche experience.
Note to self… when you live in area that cold don’t believe the hype… just get a regular car.
The problem will occur even if I get a regular car. I do very short distances causing he 12V to die... .same will happen with normal ICE vehicles
The best advice from a past owner of a 2022 k 2023 NX plug in is to never never get one!! Get yourself a Porsche Macan
I guess it depends on your needs and wants. If you are looking for a sports SUV, then you have the wrong brand. Enjoy the Porsche Macan!
You've got to plug your lexus in every night like you would your phone.
No.. I don't need to.. I don't plug to charge the hybrid battery everyday and the 12V battery I would trickle charge once a month.
@@lsft does it have a block heater?
@@mikej238 you can add one. It doesn't include a block heater. It has a heat pump.
you drive .6 kms? 😂
yeah.. 600 meters to the gym
@@lsft If its -20 outside I would drive .6 kms.
