Doesn’t matter. Tundra, GX or LX. Post your source and people will (or will not) take you seriously.

Sorry you are right, you didn’t say LX. My point still stands. You say an engine in a Tundra produced in may 25 (i can only assume you mean the engine was produced in may) died. I am also inferring that you mean that that you have extremely specific information that the engine failed in the exact way these other ones have. Is that correct? You need to provide more details. Otherwise, you are just acting like some super cool Jedi d bag who knows all but only dribbles out a little. Said another way, acting like a clickbait YouTube guy.
I think that is why you are getting some negative feedback.

With confirmed crankshaft main bearings failure? (Confirmed meaning teardown performed with dealer invoice / tech notes / etc).
This! It’s not cope to want information. I don’t think anyone on this board isn’t aware that Toyota has a massive massive f up here. But after two recalls, making a claim that nothing is fixed is a big claim. Doesn’t mean it’s not true but wow, this would be borderline criminal of Toyota.
Right on! Especially this issue being the only one he/she posts around here.

So at the time of purchase, the truck's license plate/nickname was going to be BBQSAUZ... But after it ended up like this at 1,270 miles 10 days into...

They knowingly sold the 2024 model years with an engine related issue. It doesn't matter if it was debris or design.

I just scanned this thread. OP in thread states: "Stopped by for a visit at the dealer; saw the truck torn apart, heads on a table, turbos on the floor... Spoke to the tech, #5 bearing failure."
But... there's no main bearing #5 in V35A, isn't there only 4 main bearings? Was this cylinder #5 rod bearing failed?
Could rod bearing failure also be caused by machining debris? Possibly, but could also possibly be a whole bunch of other reasons. Point is if the crankshaft main bearings didn't fail this is technically a different failure mode than the original recall.

It's a failure. End of story.
It's concerning

It's not the first rod bearing failure.
If that's the case Toyota's official "leftover machining debris" explanation is much more plausible than fundamental design issue - as any leftover debris may vary in location throughout the oil passageways. Which means as process improvements are made the failures should trend down (I believe we've already seen this) and eventually (hopefully) be solved completely.
Otherwise they really need to hurry up and give us the new Twin Turbo V8 they've been working on.

TMMAL put a COBOT online in July 2025, so only two months after this May 2025 failure.
CONJECTURE/PREDICTION: The recall will be expanded again and by the end of it, all 2025 model years will be included.
They most likely tested COBOT in 2024/2025 at Tahara before instituting at TMMAL. Pretty much the classic Toyota manufacturing implementation model.
What, really? This is your source? Like one guy in the Tundra forum that obviously had the bad luck of getting a lemon down his throat. This is a far cry from "2025 hybrid V35s are all plagued with the same issue as the non-hybrids and will, NO DOUBT, be all subject to a recall."The TERRABL Build Thread - '25 Limited Crewmax

Sudobash - thank you for posting. That is a pretty horrible story which I 100% believe. My take away from it was:
1. I hope all Toyota dealers aren’t this bad. Glad i went Lexus.
2. I feel lucky that i can afford legal bc the right move would have been to lemon this or something (I’m not super versed in this)
3. This doesn’t really add any “proof” that the engine has an ongoing fatal design flaw. You are entitled to believe what you want but this is a long way from anything other than opinion.
4. More of a question for you: do “good” engines ever prematurely fail? Is the standard for design excellence zero failure? I know nothing about engines but it seems like even “good” engines/cars have a some defects from time to time right?

Sudobash has said in the tundra forum that the failure rate in later model years is less than before. But that's a low bar, the earlier failure rate seems to be very high (>1%).
You are right in that even good engines have failure rates. On the other hand, a design flaw doesn't mean that every engine will fail. It could mean that more than acceptable fail, or perhaps they fail in a dangerous and severe way. A design which lets the engine perform flawlessly in most circumstances but catastrophically fail in rare circumstances within in the scope of use is still flawed, even if most people never encounter the failure.
It's very difficult to tell with certainty from the outside if the 2025 MY failure rate is lower, let alone low enough for Toyota, because the cars haven't been on the road for long enough yet. It could be that the cases we have seen are within the normal acceptable bounds for Toyota. Or not, in which case they'll have to expand the recall through 2024 and 2025 as well.
It could be that Toyota implemented multiple fixes since 2022-2023, some of which at least reduced the rate of failure, until now when the failure rate is much lower than before but still unacceptable, so they're rolling out changes in 2026. Or it could be that the current production methods *have* brought the failure rate low enough, and the changes in 2026 are to replace some inconvenient or inefficient measures used in the current process to lower the failure rate. Just some wild speculation.

Here's what we know:
1. LX engines built in Japan in previous years suffer from the same issues as tundra engines built in Alabama.
2. Hybrid tundra engines have failed with the same failure mode as gas tundra engines.
3. There have been at least 1 case of a 2025 tundra blowing an engine with bearing issues which could have been caused by debris left in the engine - the same problem as outlined in the recall.
I personally haven't gotten enough information to say if the 2025 tundras are failing at a higher rate than what Toyota deems to be acceptable (in other words, if the cause for recall has not been solved in 2025). If they are, then LX engines are probably similarly affected. I'm hoping that we're out of the woods, but I'm not willing to bet on it.
Something to keep in mind. Most of these bearing related failures typically happen in the 30-40k mile zone, so the 2025’s could very well be subject to the issue down the road as well. The 2022 tundras, when they first launched, did not have a ton of failures until they accumulated some miles on them.
This pesky problem is a really hard to pin down since it’s happening at such a long time after the engine has been running fine for so many miles.
My 2 cents, it would be wise to buy the Lexus factory warranty so you are not staring at a 30k+ repair bill down the road… at least until the warranty runs out.
Can Toyota just drop their new TTV8 in their flagship SUV and call it a day? We are already paying 120-130k for the LX. Give us an engine option that doesn’t have such a plagued history.
