2024 Lexus LX600 Engine Failure. GX550 Next? The Same V35A-FTS in the 2024 Tundra and Sequoia... 

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.

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...

those last v8's in the last generation of GX's are definitely going to age like fine wine

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.

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 just my two cents

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.

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.

A good reason to have bought the old tried & true GX 460!

I am glad I got my 20 Tundra. The 5.7 is no slouch. It is the most powerful vehicle I have ever owned.

I don't have much to say, but I'm enjoying my 2001 4RUNNER 251k miles original engine, transmission ,transfer case ,starter, and alternator Still running strong 💪

This ought to help clear the lots of unsold older model Lexus and 4Runners.

Precisely why we went with a low mileage LX 570 over the GX 550… that, and the latest trucks “feel” more Toyota than Lexus.

Bring back a Toyota family member as the CEO of the company!!!

I have a 2022 LX600 with 21,000 miles. The engine failed and now its being replaced.

I recently had my LX570 for routine service and I got the usual “would you like to trade in” text but this time it was followed up by 2 separate phone calls pushing me to trade for a LX600. Next time I was there I saw at least 6 unsold examples in the showroom. Normally I never see more than one LX on the lot…

THE ENGINES aren't worth $10,000 Dollars and they Want $35,000 dollars to fix New Tundra ! New Platform Has lost Reliability That Toyota was Built on !

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.

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.

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.

Toyota is starting to look like the new Ford. We're watching them give up 50 years of reputation.

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.

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 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…..

Toyota and Lexus have ruined their own brand with his turbo charged bullshit that nobody really wants

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.

I’ll stick with my bulletproof 2023 4Runner

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.

Thanks for the shout out!

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.

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.

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.

So happy I dropped out of the LX-600 wait list and went for lightly used LX-570!

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)

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.

It's getting harder to be a Toyota fan these days.

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.

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

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.

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.

GREAT INFO ! KEEP IT COMING !

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!

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

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.

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.

This is good to know, Thanks for being on top of this

Some of these bulletproof engines people speak off initially had problems that got sorted out. They will resolve these issues as well.

I think the ladder Frame is a good idea, but maybe needs more r&d

Maybe they have to up the Oil weight to 0w30 or 5w30

Thank you for the video. Great information. This is exactly why I subscribed to your channel.

Its such a bummer that Toyota made all of these engine changes..... they HAD the best engines of ANY company out there!😒

The engine isn’t even really new. The ls500 has had this twin turbo v6 since 2018 🤔 Crazy it’s happening now.

Might need to go back to the v-8s and the last gen, non turbo, v-6. Obviously, this new engine design, while designed to perform better, was not thoroughly tested up to the failure point. Should have at least run 5 new engines up to 100,000 miles of hard service to see what would fail before mass production of the engine. A 4.7 in the second gen tundra reached 1 million miles.

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.

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.

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

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 🤓

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

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.

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.

I never would have guessed the F150 3.5 ecoboost is a much better stronger engine than the Tundra twin turbo

The ladder frame is the problem. There is no way to uniformly get the proper "clamp" on each bearing with the ladder frame. It could be done but only with extremely tight machining tolerances that no manufacturer could afforded in the mass production of these engines. This was designed by engineers that knew nothing of real world mechanics. FYI, I am a degreed mechanical engineer with my Professional Engineers license in two states. I am retired from the refining industry (as a Turbomachinery Engineer) and saw these same mistakes made in our industry by engineers that lived their lives in the office rather than spending time in the operating units and machine shops seeing what goes on in the real world.

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.

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.

So glad I got my 21’ TRD ORP 4Runner that’s bulletproof with proper maintenance done can run forever. I fear the 6th gen 4Runner is going to have issues as well. At least the first year or two, but hopefully I’m wrong there. God bless~

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.

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.

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.

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. Plate C

That ladder cast piece is prob intended to increase rigidity in the block, due to higher cylinder pressures from forced induction.

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 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

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.

Meanwhile my 2010 LX570 V8 is running like a champ, as is my 1998 4Runner V6.

Tinkerer put's so much work in his video.

If the cradle is the problem, I’m guessing it’s because of the design, and they are not getting sufficient clamping force over the actual bearings, and the bearings are moving. Will need to watch the vid in the link though to see what the engineers are saying.

So two integrated water- cooled manifold, turbocharger/ wastegate combinations. Sounds reliable and cheap to replace, right?

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.

Sticking with my uz! 350k miles and still purring like a kitten!

Trying to reinvent the wheel. Is this integrated design transferring load on to that bearing and causing premature failure?

If the engine overheats, that whole frame can warp and throw off the bearing tolerances... or they warp from normal use.

It’s hard to believe that Toyota would make these new ladder frame design and not put them in test vehicles and drive them for tens of thousands of miles to see if there are any failures. Usually new things are in the pipeline for years before they are ever brought to production.

b58 love please! love the content!

Starting the teardown of a 22' tundra tomorrow for this exact thing.

With that large area ladder frame bearing block, they are not able to focus the torque to the individual bearing locations. Just a thought.

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.

Not sold on the turbo engine being the problem I’m sitting back and watching this play out however. Not in market for new car yet but this is actually a fascinating story if accurate. Have to believe Toyota will figure it out but wow.

I'm so happy I got one of the last batches for 2023 lexus gx 460

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.

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.

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.

That this design uses a Bedplate/girdle to capture the crank is irrelevant. It is an oil management issue, or it manufacturing process error.

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.

Sticking with the 4.0 4runner

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 🤔

There were 3 conformed GX600 main bearing issues. Have yet to hear of a GX550 with any issues.

Omg imagine having to pay out of pocket for a replacement engine out of warranty.

Same ladder setup for the Tacoma 4 cylinder?

Seems like that ladder style bearing is not a good idea. Anyone know if the 4 cylinder iforce max has this design?

The Honda k motor uses a ladder frame and that’s one of the best 4 cylinders ever produced

Toyota just loves to add unnecessary complexity to the block design. Cast aluminum ladder frame? Why not use nodular iron or forged bearing caps in a deep skirt block?
