He did qualify his teardown a number of times. I think this has entertainment value.I don't think this counts as the evidence. The guy shows two sentence post on FB. No followup, with actual cause, repair bill, etc. There are 100s if no 1000s of reasons why a car might not start and ends up on the tow truck. Main bearing failure is just one of them. I am not trying to defend Toyota here. Maybe there is more to it than machining debris, but this video is garbage imo.
I don't know, maybe I am naive but I find it difficult to believe that Toyota would be replacing engines without getting to the bottom of the issue. They said themselves that it costs them ~$30k to replace a single engine. This is a huge loss. It means they haven't made any profit whatsoever on a single Tundra, GX, or LX sold until April 2024... So now they are doubling down? Why?
What I did appreciate was a better understanding of this engine and all the components. It left me concerned, not so much about the root cause of this recall, right now it's all speculation, but if, in fact they want to replace my engine, I will be very concerned. Swapping an engine is not a dealership repair. The probability of the technicians making a mistake is very high.
Given this is Lexus, if an engine swap is done, I think they should go a lot further in compensating their customers. They "sell luxury and reliability". That's why we pay more money for this vehicle. I think for each customer whose engine is swapped out they should give some $$ for pain, suffering and mental anguish. Why did I buy this vehicle? My friends are mocking me.
