Greetings. I'm the tech in Kai's video. My biggest concern is that even though toyota / lexus are warrantying engines due to debris, they will absolutely under no circumstances warranty anything else unless there's "visible" damage. This means the same turbos that have had debris going through the center cartridges will not be replaced.

We've had a v35a with absolutely wrecked camshafts and cam carriers which were replaced under warranty, but they would not let us replace anything else.


Best of luck to LX600 owners !

An update from the mechanic ft in the Tinkers adventure vid wayback when.

If this is true, it is surprising. I'm used to Toyota (and especially Lexus) going above and beyond when things like this happen, and doing what's right for the owner.

I was hoping there was a holistic fix (more comprehensive replacement of critical engine parts?) that would make people happy and put this issue behind us, but if Toyota is only moving to replace components with visual damage, I hope this doesn't become a case of "whack a mole" with people chasing down other issues through ownership. What happens then, and who pays?

If people end up chasing down turbo failures or cam issues after a short block or bearing replacement, it's going to make new and used buyers lose even more confidence in these products which I don't think Toyota can afford.

I hope that whatever official solution Toyota develops is a comprehensive one-and-done solution for impacted owners.

I agree and anything before the official fix is released is conjecture.

To that end, realistically what folks are demanding in this situation and others like this for toyota specifically, to feel whole will typically not match. The situation sucks all around.

-8-9th gen corolla 1zzfe had oil burning issues. Toyota publicly acknowledged said issue only for the 9th generation, and through a series of TSBs ordered all effected customers to bring their engines in for an oil consumption test. More then 1qt/1k miles and the engine was deemed a failure. 8th gen owners were sol, and 9th gen owners only a few failed while most pre facelift 9th gen ended up failing the test post warranty.

-2azfe low tension oil ring failure. First it was a tsb. Then i dont remember if it was a class action or pure customer service that Toyota issued a warranty enhancement program for reimbursement/part replacement.

-Highlander facelift 8 speed at. Similar issue to what toyota is facing now where finding which transmissions are actually effected due to teardown requirements. They identified which production dates were effected, issued a tsb, then a warranty enchancement program. Problem was owners were effected outside the identified range, and toyota told em tough luck.

Ill try to add more examples, if I can, but again the company wants to get this done according to what engineers have identified and what works to get the vehicle back on the road and nothing more.
