Looks like the Lexus lineup is suffering from the same main bearing failures in the Toyota twin turbo V35A-FTS. These are the same issues found in the Tundra and Sequoia, they just don't see as many due to lower sales numbers.
Love to hear what you think in the comments? Why do you think the front main bearings are failing? - Auta a dopravní prostředky
Calling all Toyota/Lexus Technicians. whether your agree or disagree with me, I'd love to chat with you (anonymously if requested). If you are interested in providing your perspective/images/videos or data on how many failures (or lack of failures) you see year over year at your dealership, I'm all ears. I am not trying to bash Toyota nor paint them as infallible. Email me at cars AT thecarguyonline dot com to discuss further.
Why do you think the front main bearings are failing? My speculation is something with the design in the ladder frame/cap design. I don't think it's bad bearings as the issue has been going on for years now.
I feel like it may be a few different reasons all interacting. The main theory is tied to a shift/person not cleaning blocks properly, this mainly matches the issue up until 2024's started blowing up. Also some people are going a good 20-40k multiple oil changes etc, before the failure too. The main concern being any failure outside the first years or 12k miles in most states will be outside any lemon law protection. The engines do not have the vin stamped on them, but rather have a different serial number. I wonder if Toyota even has a good idea of what batches of engines went into what trucks.
FRONT MAY GO FIRST.. IF IT GOES TO 100k MILES, THEN WE'LL SEE MORE BEARING FAILURES.
You’re a liar .
If you throw a sheet of plywood on the ground, it’ll sit flat… if you lift up one side and put something underneath it the side that doesn’t have anything underneath it has been disturbed, right? YES. So in the past having independent bearing block if the rear of the engine that gets the least amount of airflow gets hot, the metal expands very slightly, that’s fine, everything is still within spec. But the new engine, if the rear gets hot, the front has air flowing over it, what is that going to do? The back is going to pry up on the front. It’s one of the many reasons why we have expansion joints in concrete. That’s my best guess
@@Tr0utp0nDsounds like it's the new main cap design if you watched the video
My 2023 Tundra engine blew up, Toyota fixed it. 17k miles. I traded it in two days later on a 2024 4Runner... Gonna wait a few more years till Toyota gets this right...
But it is happening in the 2024 so will toyota fix it in 2 years? I will give it 5 years when the new refresh model comes out.
Sooo they screwed you twice, meanwhile you’re paying them for their screwups and waiting for them to get better. I’m afraid to say that’s not how the markets works, they have to LOSE money to change, by you giving you them money hand over fist ain’t doing nothing to their bottom line, only yours.

Thank you for solving this! Im sure the engineers will be quite happy to hear from you! Have you reached out to them?
Toyota should build a good inline-6 engines for their vehicles, instead of this v-6 thingy. A good one, with inherent balance and smoothness.
Maybe they can copy the bmw b58
Well, they had good V6 engines.
2j in every toyota, problem fixed
It's mind blowing that the bureaucracy that now exists at Toyota is so entrenched that it could allow this bearing problem with the V35A-FTS to continue for 6 consecutive years. So totally out of character for the company.
I'm taking no chances with the all new A25A engine in my 2018 Camry. It gets 5W-30 oil instead of Toyota's "required" ultra thin 0W-16 and it gets changed every 4,000 miles instead of 10,000.
I have a 2022 LX600 with 21,000 miles. The engine failed and now its being replaced.
I had one with 1000 miles on it.....broke down....in my dreams :)
Replaced with a new engine? Or is it being repaired?
My job has one as their company car and the motor went kaput at 12k miles, it was the same type of failure

Toyota is starting to look like the new Ford. We're watching them give up 50 years of reputation.
Precisely why we went with a low mileage LX 570 over the GX 550… that, and the latest trucks “feel” more Toyota than Lexus.
Exactly what I'm planning on doing. Was going to replace my 2011 gx460 with the new gx but not anymore. Getting a 2020 lx570 with the bullet proof V8.
+ 1 here, only went for LX-570 instead of LX-600. Had this exact concern (low volume - high power engine, I was skeptical of its reliability).
I have an LX570 and wouldn’t trade it straight up for the 600. The 570 is the best car made in my opinion.
Smart move
A good reason to have bought the old tried & true GX 460!
Just like the car care nut; he got the GX 460 for his family, pretty sure he known something.
I'm keeping my 2009 GX470!

I did just that. That engine has been a round for a while is is reliable. The vehicle’s appearance is dated but who cares. That car will easily go 200k miles

Worst engine I’ve ever experienced. Been a yota fan for 17 years and I’ve had the heads replaced 2 times on my new Tundra. I currently bought my wife a 2023 QX60 instead of a new lexus because of the bad quality I’ve had with toyota recently. I only got her the new QX60 because she liked it and it does ride very nice with the 9 speed. Might just get myself a new Frontier Pro4x… This is our 1st Nissan we have ever owned.
Nice, we were looking to get a qx60 as well now that we’re enjoying our 22 Titan.

@abdulhamma6657 I have a 23' 4Runner and a 22' Frontier. In comparison, Frontier still lacks from 100% Japan built 4R but it is no slouch. I like the Frontier for simplicity and ease of maintenance, close to 40k miles on it and haven't a hiccup. BUT, if you buy your cars and keep it you have to do your first oil change at 100 miles, trust me on this.
Love my 21 Titan XD and my wife's 18 Armada...
Because Toyota quality is crap now, we went with a 2023 QX60 Sensory Dec. 2022. Love it. I own a 07 Crewmax with the 5.7. Won't touch the new Tundra. I had wanted the V8 LandCruiser but they dropped that and the LX570.

Wrong. Akio Toyoda was still the CEO of Toyota Motor Corp when he signed off on both the 3rd Gen Tundra & the i-FORCE MAX Twin-Turbo V6 HYBRID powertrain for which he pushed.
*CEO Akio Toyota has often suggested he’d like a hybrid for just about every possible model. Could one eventually follow for Tundra? And in a conversation with TheDetroitBureau, Toyota division chief Fay suggested one might come out of the Japanese maker’s new joint venture with Ford. The two have teamed up to develop hybrid systems for larger vehicles that could include future truck models.*
Furthermore, Akio Toyoda was still in charge when the 3rd gen Tundra powertrains started failing.

2014 tundra 5.7
My first car was a 2000 Toyota Tundra with the 4.7 V8. The only gasoline V8 that I still recommend to people to this day, absolutely bulletproof that thing was. And even for being such a relatively low displacement V8 it still had a ton of low end grunt. Saddens me to see one of my childhood favorites fall to such lows.
Just bought a 2021 trd pro tundra. Hopeful to keep it for a very long time. Might be one of the last true trucks in its class left years down the road.
The 3.4 v6 liter engine made by toyota cost $28 grand. The recent 5.7 V8 cost $8000 and it doesent break like the turbo 6 cylinder.
At this point, I’m simply not interested in ANY of these new vehicles. Between CAFE standards, turbos, data mining and ridiculous prices, I’ll pass on them all and stick to
CAFE isn’t to blame for bad engineering. Trucks and trains have been using turbos reliability for decades. And in case you missed the video: the problem isn’t the turbo, it’s the lousy main bearings eating themselves up. Even the Chrysler Pentastar doesn’t do that. The fact that this thing left the drawing board at Toyota is an institutional failure.
“The problem isn’t with the turbos “. …….yet…..
I’ll stick to our 21’ GX460 with eco mode off. I like to let her drink and breathe the way she’s made to with all her 8 cylinders. Beast mode!
2023 and 2024 Toyota & Lexus TTV6 are still having bearing failures. It's a design issue. Toyota knows it's design issue, but they are hoping most make it past the warranty period. $30K-$35K repair outside of warranty.
I've been saying this about these bearings since they decided to push 400hp out of a V6 3.5, and have posted this on other vids even before the failures started being talked about. That is, unless they increase bearing areas, they're going to have failures. It might be ok to do this in a light vehicle where the engine isn't under heavy load very often, but in a heavy vehicle expected to tow and haul, it's a problem waiting to happen. That's why aircraft piston engines are overbuilt. So that they can withstand 100% engine load reliably during takeoff. I don't care if Toyota makes the main cap one unit, if the bearings are still small. They are taking all the stress that their V8 made, and now expecting a smaller piece of iron to do the same. 6 pistons, 6 rod bearings, fewer main bearings all need to absorb the same power as the V8 did. Sudden bearing failure only occurs from lack of oil, whether it's a plugged galley, or the oil film psi has been exceeded by overloading. However, they can make this work with turbos. After all, plenty of turbo diesels are V6, but they're built heavier, and have increased bearing surface areas to take the increased stress, and prevent oil film breakdown.
I wonder how light the oil grade is too - in the compromise of economy
Technically there is no contact between a bearing surface and a crank journal - at least there SHOULDN'T be the way that oil technology works in modern engines - boost obviously changes everything but still it is odd they are failing.
@@tomh894 Yes, there should be no contact between the metal components. OIl film breakdown caused be excess force, or oil starvation will cause it. In extreme cases, like military tank engines, silver bearings will be used, just in case oil supply is disrupted.
Main bearings don't care about HP
It's a quality issue I've seen damaged bearings due to a cylinder missfire on a heavily boosted engine
@@Airman.. I can see where a misfire issue would cause issues. It's true about mains. You can build a V8 until you split the block in half before the mains fail. But maybe they weren't designed big enough in the first place. There's a reason why diesels have increased bearing surface areas to handle increased compression ratios. It appears it is just the front bearing with the problem, which makes me think there's a oil flow issue to that area. I don't know how the the galleys are set up. It looks like the caps are made of aluminum too. I don't think that's a great idea tbh. We used to form them from steel powder, and they worked.
This is similar to the transmission failures that happened on the 2nd gen Tundras for the first 3-4 years when the 5.7 i- Force first popped out along with the 4.7L i-Force with the blown transmission issues started. I hope for the best as they work through these parts manufacturing and production of the 3rd gen.
I don’t think main bearing spinning or grenading it’s a bad thing. Toyota designed this to allow customers to enjoy a brand new engine every 5-6 months, which is more fuel efficient than the old V8, thus reducing climate change.
Sure, these cars probably won’t last and people will need to buy more new cars and engine replacements require more engine parts to be produced and shipped. All that has lots of carbon emissions and may negatively impact climate change, but ONLY if you don’t turn the graph upside down. Modern climate science does not care about such things. The only thing that matters is the stated intent to reduce climate change, and I fully believe it, even with higher carbon emissions.
My final takeaway - I will ONLY buy new cars, because they are infinitely better, even with quarterly catastrophic powertrain failures. The only advantage and difference the old V8 has over the new engine is that the V8 works and is reliable - features that are not that important in a new vehicle. New cars come with features that are more valuable than a reliable engine-Bluetooth, Apple car play, LCDs gauge clusters and touchscreens.
The complexity of this engine is mind blowing. The cost to fix/replace engine is so high that I would not buy it. This is as bad as ev batteries…..
It’s wY worse ev batteries usually give you 8/175k trouble free and most can be had for less than the 35k this engine costs.
No EV batteries aren’t “horrible”. People have had over 500k on an old design battery pack
Soon they will be lasting 1 million miles. And when people figure out used EV for 25k can last 1 million miles…. Well what do you think will happen
EVs actually have a lot less moving parts than a conventional engine. It's the battery replacement cost that will kill you.
@@Akiss- EV batteries are designed for the life of the vehicles. I heard the same “huurrr…duuur the batteries will fail” garbage when hybrids first came on the market decades ago.
@@ClockworksOfGL This Toyota engine is designed for lifespan of the vehicle. Very short lifespan...
So happy I dropped out of the LX-600 wait list and went for lightly used LX-570!
Watch out for that airbag warning light to come on. Ben Hardy had this happen on two Toyota LC200s at the same time just now. One built in 2021, and the other in 2022. Something to do with rust in the sunroof area doing something with the wires. And the design of the Lexus 570 is basically identical.
@@LivingRetirement Thanks for the heads up. I was unaware that this issue could happen with any car with a sunroof.
Weve already had 3 of the new RX with the 2.4 turbo , throw a rod out the block. Same engines in the nx rx tx the new tacoma and new 4runner.
holy cow...sounds like the early ecoboosts.
Wow…
Bedplate / ladder frame is not the issue because same design has been used by Nissan in the VR38 twin turbo engine for the GTR and in all VQ series. Those two are solid engines.
Exactly, same design in Hondas f20c s2000 engine, which first year was 1999, not a single block issue
My guess is the main ladder frame casting process needs tweaking. Ask international how many blown 6.0 head gaskets they had from rushing the casting process. The machining can be spot on and meet tolerance during assembly, but only after heat cycles will the cast iron move.
This ought to help clear the lots of unsold older model Lexus and 4Runners.
When i bought my 2020 Land Cruiser brand new back in 21 my next door neighbor goes it's outdated fast forward to January 24 he went ahead and financed a LX 600 nice truck no questions asked and exactly at 7100k coming back to NYC from Boston he calls and goes im hearing kind of a knocking sound, sure enough main bearing went and ruined everything in between, today may 21st 2024 the Lexus is still at the dealer been there for 41 days waiting on a new engine, glad i own a 200.
This engine started life as the engine of the LS sedan. It was not originally designed to be a truck engine. It was handicapped from the beginning.
Its such a bummer that Toyota made all of these engine changes..... they HAD the best engines of ANY company out there!😒
Not a warranty expert, but I would think these failures would fall under the lifetime powertrain warranty regardless of age or miles. Would still stink, but I'd bet Toyota will stand behind the repairs.
GREAT INFO ! KEEP IT COMING !
It’s that new twin turbo V6 they completely redesigned it and released it in 2022. I wish they kept the V8 but you know emissions
It's been happening since 2018. It's on the Lexus forums. Difference is, the LS500 sells in much lower volumes and particularly to an older crowd that doesn't necessarily care to report problems on the internet. It's the very reason I avoided the LS500 back then and went with a K900 3.3T instead - 62K miles, zero issues so far.
Interesting, I'll try to poke around and find those forums.
@@TheCarGuyOnline Yup. If you google '2018 LS500 on 2nd blown motor' it'll lead you to them. There have also been numerous reports of oil consumption. It's definitely a defect (perhaps with the supplier?) and imho not too dissimilar from the very recent Honda/Acura recall on all of their V6's due to seized connecting rods.
@@philhenderson3516 Interesting… 🤔
And this twin turbo V6 story is exactly the reason why I ended up buying older LS460 instead of newer LS500. I want my V8 with no turbo BS. Toyota, wake the heck up.
I suppose the good news is the dealers will become slightly less exuberant in applying market price adjustments on these models. Ha! (Love my sweet '15 GX460 Lux)
You would think that wouldn't ya. However people will still line up to plop their cash down and won't care. A vast majority of people don't even bother to research the cost of insurance for a new car let alone mechanical issues.
I think the ladder Frame is a good idea, but maybe needs more r&d
This is good to know, Thanks for being on top of this
Thank you for the video. Great information. This is exactly why I subscribed to your channel.
The t24-fts 4 cylinder turbo has the ladder bearing too I think. The Car Care Nut mentioned it in his technical review of the 2024 Tacoma. If there turns out to be something fundamentally wrong with that approach then Toyota has a big problem on its hands.
That design might work ok on the smaller 4banger, time will tell.
I googled T24A-FTS failure and didn't get any hits.
@@verlaryder hopefully that remains the case. They’ve gone all in on that engine. Highlander, Tacoma, and now the new Landcruiser and 4runner.
At least Totota and Lexus will cover the costs of the repairs. You would think these engines would have been thoroughly tested. How embarrassing for both Toyota and Lexus.
When these garbage vehicles hit the use car market, the 2nd owners will be living a nightmare out of warranty
In the LX600 and tundra the engine is giving 400+ hp and I think that's why they lower power of the same engine on the GX550 to avoid issues on the engine 🤓
Some of these bulletproof engines people speak off initially had problems that got sorted out. They will resolve these issues as well.
Even the vaunted Toyota can't make such a huge change to the new engines without real-life major problems. I own 2001, 2020 and 2021 V8 Tundras, buying the latter specifically to avoid gambling with the new TT engines. These are work trucks; if they break down my company can't work. Zero problems with the V8s. This is also why i raced to buy the last V8 2023 GX460. I change the oil every 3000 miles.
Thanks for the shout out!
Well truthfully you did all the hard work. I must have watched your video 5 times. I really want to figure out why this issue is still occurring, hopefully we’ll get some indication from Toyota at some point? I was in the camp of people wanting to buy a new tundra and I just can’t take the risk…
Still have my 2000 Tundra 3.4l - now with 210k miles on it. It doesn't burn or leak any oil and is the most reliable vehicle I've ever owned. Also have a 2011 Tundra 4.6l with 135k miles - runs like a top but not quite as reliable as the older V-6 - minor oil leaks on some spark plug towers.
The V35 was first used in the Lexus LS sedan, but now no LS. For truck use, they could/should have developed a sturdy inline 6 since it would easily fit in a variety of trucks. At the same time, think of the money that could have been saved. ONE turbo, ONE head, ONE air cleaner, ONE mass airflow sensor, ONE exhaust manifold, NO balance shafts, etc, etc. ...and smoother running/better balance at the same time.
There are 4 LX600s at a local dealer here in Houston waiting for a motor for rod bearing issue. So no.. this isnt an isolated issue. That ladder frame design for the main caps could definitely be the issue.
That rules out that manufacturing plant issues since Lexus would have used imo engines made in Japan. That points to a design flaw or teething problem.
Maybe Toyota hired people that help build the Kia & Hyundai
I have pesonally done a couple at the lexus dealer ship on the LS500. The rod bearings have spun out and Ive had to replace long block or short blocks, cylinder heads, and timing covers due to this. I have a couple of short videos on my youtube account showing this
On the LS too?
@@erickonassis6310 yessir LS500
Sticking with my uz! 350k miles and still purring like a kitten!
8:40 That's a big IF.
Not gonna hang around until that happens and throw 60-75k at a truck that already broke my TRUST in 2022 Toyota vehicles.
I'll just buy something older with as few miles as possible. 1st gen and 2nd gen Sequoias and Tundras are looking mighty fine right about now, same goes for the 100 and 200 series LCs.
Absolute shame. They discontinued the best engine they ever made.
It is really sad to see an empire such as TOYOTA & LEXUS start to fail this bad. The issue is huge in the middle east as well.
GM did the same thing with the Cadillac Northstar. Navistar did the same thing in the 6.0 and 6.4 powerstroke diesel. In that application it is called a bed plate and it takes the lower half of the block away. None of those engines spun any main bearings.
I read it was a manufacturing flaw. A limited number of engine blocks were not cleaned sufficiently leaving metal shavings in the block oil passages. Toyota correct the process but there are affected engines in a number of vehicles.
So two integrated water- cooled manifold, turbocharger/ wastegate combinations. Sounds reliable and cheap to replace, right?
The girdle is an old design. I remember the Honda K series having it. The problem is the 10,000 mile oil change. Doesn’t matter how good manufacturing has gotten. There is where especially in the first thousand miles and those little pieces of metal along with leftover sealant circulate, and they worked their way into the crankshaft bearings and they chew up bearings left and right, I will never subscribe to that thought process. It has been revealed over and over that all manufacturers have been strong armed into the EPA’s 10,000 mile intervals they get carbon credits for doing this. It has been stated on record that this oil change schedule will get you outside the warranty, but that’s about it.
exactly why an early first oil change is critical...say 800 to 1000 miles...
@@joelawrence56 1000% agree
I never would have guessed the F150 3.5 ecoboost is a much better stronger engine than the Tundra twin turbo
Well. Compared to the first gen 3.5, this is probably still a better engine, compared to the latest 3.5…Ford has the edge and a lot of years/experience tweaking. Did they go to a wet oil pump design in the latest 3.5? I can’t remember, I know is the 2.7l did…
@@TheCarGuyOnlinecrap on the oil bathed belt driven pump all you want, no documented oil pump failures with about a million more trucks on the road racking up miles than the second worse selling 1/2 ton, the Tundra.
The ecoboost was a nightmare when it first came out.
If you like replacing cam phasers every 60k miles buy an EcoBoost. That went on for over a decade and still don’t know if Ford fixed it.
Trying to reinvent the wheel.
Is this integrated design transferring load on to that bearing and causing premature failure?
I think the thin oil 0w20 they use in the US is the problem ,here dealers around the country suggest using 5W 30 oil we have never heard of this kind of problems
The new engine with cap girdle is a better design and stiffens the whole block. They just mucked it up somewhere. Machining swarf in the oil passages? They should do a longblock as main failures is likely going to trash everything anyway. The overall design brings the motor design up to the standards of the best, but this has all been done by others before, so not bleeding edge stuff.
I bet it’s most likely production issues than engineering/ design.
The engine isn’t even really new. The ls500 has had this twin turbo v6 since 2018 🤔
Crazy it’s happening now.
It's been happening ... even with LS500 ... that car is just rare.
We don’t have that issues in Middle East ,,, in lc300 maybe because it’s built in japan
I guarantee you it has something to do with the different coefficients of thermal expansion for the lower aluminum block section mating with the cast iron “ladder” crank cap section. This already proved to be an issue with aluminum heads on cast iron blocks which made head gasket designs even more imperative.
If this is the case, would the main bearings on the ladder frame show different wear vs wear on the engine block side bearings?
Toyota Plan of Action: 1.Redesign bearing ladder frame or just get rid of it.. call it a new version of the engine. 2. Make at least 10k of these new engines 3. Recall all Lexuses and Toyotas with this engine and replace them all with the redesigned engine 4 give all recalled cars a nice internal and external detailing. 5. Write off losses. 6. watch the profits roll in
We've noticed similar failures year ago on this engine on lc300 in middle east
The ladder frame it’s not the problem, unless the ladder frame has a some crazy issue, like from the casting itself. Honda K series are built exactly this way with the ladder frame in a 4 cylinders. Now one thing I know, is that starvation in the main bearing comes from low oil when oil pump cannot keep up for any crazy reason
Are honda ladder frames made out of same aluminum as the engine block? The ladder frame on the V35A is cast iron, and might be experiencing different thermal expansion issues?
The ladder frame is made of aluminum with iron inserts imbedded where the bearings seat, so do people even watch or listen to the actual video? 😮 the split girdle design is the superior most rigid design, it’s more expensive to make but easier and faster to assemble reserved for mostly high performance applications, bearings aren’t supposed to actually ride and touch metal on metal, the whole concept and actual fundamental principles of oil film between bearing’s and crankshaft and rod bearings is the same ride on a thin cushion of oil, for the calculated load of surface area and forces upon it, therefore only two possible culprits exist here, the load area of the bearings is insufficient for the loads demanded of it or oil starvation and the dark horse contributing factor factory recommended 0-20w oil weight that’s some pretty dang thin oil, combine that with maybe insufficient bearing surface area hot running turbo engine and high performance high torque spells disaster, btwn this and the turbo 4 Tacomas 4Runners and landcruisers it doesn’t look good at all, this could be the death knell for Toyota, all dependability, reliability, and value in your brand all taken down in one swell swoop of a decisions on these new generations of Toyotas. Rip Toyota legacy 😢
@@jjampong yes Honda ladder frame is made of aluminum as well
b58 love please! love the content!
Usually oiling or heat issues are at the root of main bearing failures - this "ladder" design probably is superior to individual main caps but only because of rigidity for the block itself. Many past engine design's improvements were based on more fasteners which prevented movement in the caps. This same logic is likely what has been applied by Toyota for their design - and also simplicity. I find it stupid though because if you have an issue then its a bigger job.
Very unusual for Toyota to have such an error. I think they should just extend the warranty period for owners to 100,000 miles and quickly redesign the engine.
A new short block isn't fixing the issue. There are owners reporting around 40k miles and are on block #3. Seems even Toyota unfortunately isn't immune to engineering issues with these new design turbo engines. With all the supposed testing products go through it's hard to understand how problems like this get by the Mule stage and into final production 🤔
This is going to be such a bad recall for Toyota to do. They need to get on the ball and find a fix asap.
Anything new is not proven.....period....Toyota will learn from the current mistakes and the second generation will be be better. This is main reason the Japanese uses an engine families for decades before retiring them....they get to perfect them to get them to thr bullet proof reliability they are known for....just my two cents
22 tundra sr5 4x4 still going strong. Sounds no different than the day I took delivery.
Using the "Severe service" schedule due to frequent towing and heavy payloads. 5,000 mile max on the oil changes.
yeah that's what I would do, either 3-5k oil changes on turbo engines. I had a 3.5 ecoboost for a bit and the oil would be jet black at 4k.....
Great video, I will be interested to follow this issue and see just how widespread this problem becomes. Rather than cast iron I wish the main cap girdle was made machined from a solid billet (steel or aluminum) vs a casting. Far more expensive to manufacture but would likely do a better job a preventing deflection under load. While the engineering flaw is without question on Toyota, alot of OEMs going to downsized turbocharged engines is directly the result of the government meddling too much in the affairs of the automotive industry (CAFE, CARB) forcing them into overly complex engines to eek out miniscule improvements in mpg & emissions gas reductions. Big brother needs to back off.
People lost their ability to build solid engines. What time we live in
Seems like that ladder style bearing is not a good idea. Anyone know if the 4 cylinder iforce max has this design?
The 2022 Toyota Sequoia has the 5.7 as the design didn’t change until 2023, not sure if they made a mistake but just wanted to point it out.
This might be metallurgy related to the bearings or that cap ladder frame. I really wish they had just gone with the b58 personally for the tundra and gx550 and lx600.
This is also why cpo gx460’s are still selling close to msrp.
I own a 2019 LS500 with a little over 58k on the odometer, no issues so far……….but this is what happens when car companies rush to jump on the bandwagon, they should have kept the V8 on the LS, LX, GX, Sequoia and Tundra platforms, at least as a option!
I would keep that oil changed every 5k
@@BrianNC81 absolutely
Please Toyota, do the right thing and make a recall!!!
I have a 23 tundra. I change my oil every 3000 miles and im nearly 3 quarts low each time. Makes me wonder if i could even make it to 10000 before a bearing would fail from low oil pressure.
Sell it while u can bro, i was gonna get the new tacoma but i didnt like how they over priced it super high. I got a frontier pro4x for $11k cheaper. Think i made a good choice lol.
This will end up in a class action lawsuit. All Toyota and Lexus owners will be able to call a specified lawyers office, register and the law firm will get 30 percent of the aggregate.
The remaining will be divided amongst the owners of the vehicles, which will be a small amount of money compared to the losses that we will suffer.
Thanks Toyota. Not sure what to do at this point with my new Tundra.

With that large area ladder frame bearing block, they are not able to focus the torque to the individual bearing locations. Just a thought.
That ladder cast piece is prob intended to increase rigidity in the block, due to higher cylinder pressures from forced induction.
Why is the CAFE 0w-20 10k OCI being overlooked. High torque TT V6 of this design has been proven to dilute and contaminate much more than naturally aspirated engines. Change your oil at 1.5k and tell that oil looks like it has less than 2k. Many have reported lab tests resulted in confirmed oil contamination, in such case compromised film strength.
The most compelling theory I’ve seen is the oil system is flawed, that the way lubrication is routed means the main bearings are prone to momentary oil starvation. There’s lots of turbocharged V6s from other manufacturers that don’t eat themselves alive. Toyota screwed up here.
Really this is justice. To be honest with you this is long overdue. You see starting around 2017 Toyota had to start the knee to the governmental agencies that have decided that they're also engineers and have changed the demands of what they expect out of the automotive designers. The American car companies have had to go through this for decades now. They were spared no expense on being abused for a long long time. Remember back in the day when the General Motors Corporation had the 3800 v6s and they put them in everything. Will the government didn't like that. I mean they were old archaic V6 after all. Turns out they were also the best V6 probably ever made. Follow a very closely by the 4300 V6 which was also pretty damn bulletproof. But they both have pushrods in the government decided that that's not efficient anymore. So began the long tradition of overly complicated overhead cam engines. Some work, some are just more failure, but at the end of the day none of them are any bit competitive with the old pushrod series engines. They also had to incorporate fuel-saving Technologies like shut the car off at stop lights and AFM and all sorts of other b*******. That's the reason for it had to switch to Twin Turbo engines. And all the Toyota Fanboys talked about how the American Products were f****** junk. Now look where we're at. All the sudden they had to catch up. And as it turns out they're f****** worse than anything American ever was after all. Don't feel bad, Nissan's been having the same problem for 5 to 10 years now too. In fact the Altima is probably the most unreliable car ever made. Subaru and Honda haven't been spared either. Subaru had to switch to cvts which has caused nothing but problems for them just like nissan. And Honda's Transmissions haven't really been great for the last 20 years. All changes that were made because of folks within the government who think they know more about cars than the people that design them. The only thing these people have done is make all the car companies have to take chances they don't normally want to take and charge way too much money for a vehicle and. And at the end of all that the only thing you think about is how your car 20 years ago was 10 times more reliable, and still affordable.
Toyota needs to get their act together, with numerous engine failures on the Tundra and now this, I'd be hesitant to buy a new toyota truck or SUV until they work this out.
It's getting harder to be a Toyota fan these days.
Are these the I force max engines?
Maybe they have to up the Oil weight to 0w30 or 5w30
That this design uses a Bedplate/girdle to capture the crank is irrelevant. It is an oil management issue, or it manufacturing process error.
I worked in a machining plant that made crankshafts and I ran CBN and Conventional grinders. We had to check our cranks down to the micron and if the had any lobing or out of spec bearings (pin or main) we had to troubleshoot everything down to the grinding wheels. Re-touch the the ruby off the calibration bar and literally re-teach the machine, then run a certain amount of parts within spec in a row before running production again. But guess what... depending on management, we'd release the parts before these tests and recalibration were done. We had a run of engines (cummins mainly) blowing up and boy what a shit show. Certainly Lexus has more stringent QA than a greedy German company in America that is run by Brazilians... right?
haha...you'd hope they would but time will tell.
@@TheCarGuyOnline welp... There it is lol. The final inspections staff is going to get fired 😬
I'm so happy I got one of the last batches for 2023 lexus gx 460
Just throwing this out there. If your out of warranty with a blown turbo engine can you replace it with a 5.7 engine? at a cheaper cost?
