First time Tahoe owner (GM for that matter) and recently purchased a 2023 Tahoe LT brand new (first new car purchase). At about 300 miles I randomly got multiple errors and flashing check engine light with engine running rough(photos and error codes from OnStar diagnostic). Traction control error, forward collision disabled, service ESC, etc. I was almost certain it was the dreaded lifter issue but couldn't believe so early at 300 miles. I was able to make it back home and OnStar required I get it towed into the dealership. After sitting in the lot for a few days, the dealership reset the check engine light and everything was fine. Service attributed as a software anomaly. Brought it back home and fast forward 700 miles and the issue occurred with the exact same thing. 3 days before we are supposed to take it on the first long road trip for the holiday.
Anybody experienced this issue? Have a suggestion on what to do? Wondering what my options are because I'm getting to the point of demanding to trade it in and see what the dealer can do for me because two events where the truck is inoperable and had to be towed in less than 1000 miles for $65k+ is unacceptable. Appreciate the advice. Merry Christmas!
