All the information seems plausible, just very hard to trust a AI generated video. Also I dont think there is data for 2027 at least to the public.

Paging @sudobash
Toyota has now triple downed on the message of:
There can be manufacturing debris in the engine. Due to type of pressure on #1 main bearing in certain cases this causes problems. After installing "an improved main bearing" in 25, all is good. The new bearing went in the Japan factory first.
My opinion is that it did in fact work, Toyota isn't criminally lying and if you have a 25 or 26 you're in the clear. If you haven't been included in a recall up to this point then just enjoy a kick ass engine.

Looks like summary is they were able to recreate same damage to number 1 engine main bearing with introduction of debris. However, with an improved main bearing, the engine shouldn't fail now. Did i get that right?
Nope. They haven't done the study on the improved bearing, so no public data. This report looked at previous changes that were implemented by Toyota after the previous recalls (improved cleaning procedures, changed camshaft clearances) before they changed the bearing, and concluded that they didn't stop the engines from blowing up, while saying nothing about the effects of the different bearing used. Right now it's hopes and prayers that the bearing change fixed the problem, but all their other fixes haven't, and there are rumours of upcoming changes in June, so I don't have much faith.
It's similar to what was written in the previous recalls - "we found debris causing issues in engines made in period X, so we implemented changes in period Y".
Then next recall, a year later- "we found debris causing issues in engines made in period Y, so we implemented changes in period Z."
Yes, you did. That is the conclusion from the document posted by Snowman. There are ZERO cases of the "debris issue" with engines produced with the improved main bearing. I am not talking about YT-clickbait-influencer-heard-in-a-Tundra-forum thing, I am talking hard evidence. That is a fact today. May change tomorrow? Sure... May a cat 5 hurricane hit the US tomorrow? Sure...May a lightning strike a tree in the park? Sure...May a HG pop in a Tundra or 200 V8? Sure... on and on.
The difference is that - to use your example - the changes implemented in period Y were NOT the same as the much more robust changes implemented in period Z. In addition, like i said above, there is ZERO evidence of issues after implementing the period Z changes.
I understand the lack of confidence but Toyota did not issue this letter now out of the blue. They did finalize a study with the supplier and I doubt their legal would have approved this letter if the conclusion was not solid.
Factually incorrect.
There are a ton of cases for the 2025 and 2026 model year failures.
The big consideration is the issue doesn’t usually occur until you’re in the 30-40k mile range, so it takes a couple of years for the issue to statistically present itself.
That’s why the issue wasn’t well known until 2023-2024 when the 2022 models were starting to blow.
With a more robust bearing, are you now going to start seeing failures later on in the mileage when you are out warranty? That’s something to consider if they still can’t figure out how to clear machining debris after 8 model years (starting with the LS 500 back in 2017). And yes, this issue was known for LS 500’s, well before they started dropping them in the truck platforms.

Here you go! I have plenty of other examples as well. This would have been with the revised bearing, but it seems like Toyota left too many machining debris artifacts in this one for the more “robust” bearing to handle.
Not how it works. You first made the claim that no engines made with the improved bearing have failed because of debris, so you need to provide evidence for your claim first.
And no, googling "26/25 MY tundra failures", then disregarding all of the owner reports that pop up because you don't believe them, then saying "oh I didn't find anything they must be all fine" doesn't count. That's just cope.

What was the saddest about that guy was he actually was on board with the whole "25/26 trucks are fine" thing. Then his blew up. He's now in a taco.
I agree, that is sad indeed, and I believe he spent many thousands of dollars on mods to the truck right before it went since he had so much confidence in it.
Interestingly enough, the techs who work on these motors open up the T24A, and see how much more robust those motors are compared to the V35A. Thicker cylinder walls, deeper skirts, and an all around more of a beefy looking design.
It would be nice if Toyota could simply make an inline 6 variant with 2 more cylinders added onto the back of the T24A to keep the rigidity intact. I still suspect this machining debris excuse is getting long in the tooth, and they are not being 100% truthful with their failure reasoning.
With how long the hoods are on these new platforms, they should have room to fit an inline 6 instead.
Han? So now you think I have to show “negative” proof?! LOL. You said my statement was “factually incorrect” so you must believe there are tons of examples out there. I just asked you to show us one or two. Still waiting, not coping.
Please read again what I said about tundra forums and yt influencers.Here you go! I have plenty of other examples as well. This would have been with the revised bearing, but it seems like Toyota left too many machining debris artifacts in this one for the more “robust” bearing to handle.
That's not what negative proof means. You can easily prove that you statement is true by showing that all engines are working fine. Because I am nice, I will also accept any statistic showing the aggregated failure rate is in line with what Toyota expects. If you can't, then don't bother asking other people for proof because you don't have the ability to provide it yourself. Put up or shut up.
No, the existence of only ONE MY25/26 tundra with these engine problems will disprove your claim. What do you think
means? "A few"?
This is just moving the goalposts because you are in bad faith, and have been for a long time. Zill posted an example of someone with a bad MY26, who has an extensive post history and even pictures during ownership, and of course you choose to ignore it.
If you're going to willfully ignore everything on social media, what "examples" are you looking for? Are you waiting for someone to tow their truck to your front yard so you can look at the engine code?
To demand such an extraordinarily high level of proof for what is a developing story, while making wild sweeping claims of your own like "ZERO cases exist" without producing any proof yourself, is completely moronic.

Showing that all engines are working fine?! LOL. So you are suggesting I go to every owner of a V35A and get proof that their engines are working fine? I can't think of anything more moronic than this. YOU are the one challenging my statement, so go ahead and challenge the right way - by showing some evidence that I am wrong. I will happily stand corrected if you do so.
What do I think? I think you are not able to show this without turning to ONE guy in a Tundra Forum, which, to me, shows absolutely nothing. Go ahead and post some official data from the NHTSA or Toyota showing the failure of a V35A post improved bearing. I will gladly accept that.
I am just not taking "social media" as something definitive and as proof of a failure. There is an infinite number of bots and "influencers"/"youtubers" just looking for clicks to make meaningful cash in these platforms. No to mention aiming to tarnish the reputation of a manufacturer to benefit another. Lots of them HERE in MUD. Show me a true investigative article or an official report that supports your claim and I will be the first to admit I was wrong.
I will wait.
until then, I am with Snowman.Just to clarify my position - I am not claiming it's a "perfect" engine or that it will have zero failures. My position is that based on the changes made, I feel very comfortable with my odds of having an engine that doesn't blow up. Would I prefer that it had a hopped up version of previous V8 instead? Sure of course, who wouldn't! But thats not possible in the world that we collectively voted for (Green initiatives). I really like the engine in the 700h. The torque fill makes the engine extremely smooth. In my 1 of 1 opinion, the J300 and 310 are still the best made cars in a sea of automotive garbage.
Yes, it is a pain in the butt, but it is finite and achievable. A "negative proof" would be if the proof would be unachievable due to some infinities, such as proving no other life exists in the universe, because the universe is infinite. I don't expect you to go look at every tundra, this comment was to show that you have no idea what a "negative proof" involves.

Again, you claimed a point first, so you need to show proof of your claim before asking me for proof of my challenge. Where is Toyota's official report saying that the bearing improvements fixed the problem? You can't find any, because it doesn't exist. You are making a claim without evidence, presenting your speculation as fact, all the while yelling at whoever dares question you to give the evidence that you can't even provide yourself. This is, quite frankly, pathetic.
There is a world of difference between you and Snowman (sorry to talk about you as though you're not here). Snowman clearly stated his OPINION that the bearings fixed the problem. I am happy to disagree with him but I respect his opinion.
What I do not respect, however, is you presenting your opinion as fact. For example, your characterisation of the bearing change as a "much more robust", when there is zero official data out from Toyota describing the efficacy of the changes. There is, in fact, no data even regarding what these changes are, so you would have no idea if the changes are robust or not, even if you were an automotive engineer.
The only thing Toyota said about the bearing is that the bearings have been "improved", which is exactly the same language they used to describe the machining processes which turned out to do nothing to solve the problem.
Buying a car is difficult and expensive. There are too many ad men out there lying to you to make a quick buck. It is already enough without people like you shilling and hallucinating facts more than chatgpt.
I honestly don't even think I would prefer the old v8 to this if the v35a was fixed and reliable - that hybrid torque is just so good for crawling. But that might just be a skill issue on my part.
Wish we could get a stateside Land Cruiser with a factory built 22RE...
