Hey Everyone, there have been 2-3 videos come up on my YouTube feed in the last 24hrs that claim that Toyota has identified the root cause of the V35A issues beyond the aforementioned debris cause. Has anyone else seen these videos? Is there any validity in these claims?

Which videos are you referring to? In the latest recall of the engine Toyota had admitted that they changed out the main bearing that fails the most with a harder material which tends to point to them, not thinking it was entirely a debris issue.

I shouldn't post questions during work hours! Upon further review, i.e. actually watching these videos or at least part of them, they don't contain any new information that you @TheCarGuy have not already covered. Since I'm a new user, I cannot post the actual links but the 2 videos that came up on my YouTube feed with versions of "Toyota ADMITS the problem is more than debris" are from Untamed Motors and Autotrends. Sorry for wasting everyone's time with this nonsense...

The biggest smoking gun in the last recall report was Toyota's admission of changing the main bearing and in the recall report, it felt like they were really grasping at straws. They are trying to find root cause but, I really get the feeling it's more than debris, as do a lot of other people at this point.

This document has a lot of interesting investigation details if you have the time to read, it will tell you everything you need to know with regard to what Toyota says, then you can read between the lines 😃. https://static.nhtsa.gov/odi/rcl/2025/RMISC-25V767-8528.pdf

Let me know what you think about the chronology.

Thanks for the article...very interesting indeed...I've been wanting to pull the trigger on a new vehicle as mine is now 23 years old...I was really, really hoping that the 3rd gen Tundra was going to be the 2nd gen + improvements and modernization...looks like they just really dropped the ball on this one...

I think the number of failures are getting better/lower, but still not to Toyota standards for sure. The 2nd Gen Tundra was and still is a pretty safe bet, people just upgrade because they want new features, more power etc. I'll continue to watch the 2025 and 2026 on my channel, it will be interesting if they can ever resolve the issue completely.
