Sorry to pop in here and deviate a little. We’re going to test drive some 21, 22 tahoes and Yukons this weekend… all 5.3. What should I be asking? Getting suspicious these were traded cause someone knew they had bad drivetrains.
Is there a way to know if it has the engine with the bad supplier parts?

They identified the bad supplier parts in the 5.3 motors from Sept 1 2020 to March 31 2021 engine build date not vehicle build date. On the 2021 Tahoe and Yukon I would probably stay away from that one unless it was already repaired or outside the engine build date. When the vehicle is built lets say in May the engine was probably built 1-2 months before that it's a question to ask the selling dealer if the repairs were made on the 2021.

This is a long shot. But someone really knowledgeable about the part numbers and packages willing to look at a dealer packet about one the vehicles I am looking at?

Carfax will show the repairs I’d imagine too, and most dealers will/should provide.

Yeah I have the main packet. Wondering most important things to look for.
Only has 60k mile GM warranty... which might be a deal breaker for me...
Also looks like it came from up north, why the 3 owners. Anything to consider there?
