My 2019 Chevrolet Tahoe Premier equipped with the 6.2L V8 engine has experienced a major internal engine failure. The dealership diagnosed camshaft bearing failure with a recorded misfire on cylinder #5. The engine oil was drained and inspected and no significant metallic debris was found, and the dealership noted no evidence of abuse or neglect. Intermittent drivability concerns were present over the life of the vehicle and were addressed through professional diagnosis and repair each time. The vehicle has been properly maintained since new. Just months prior to this failure, the vehicle underwent full diagnostics and significant repairs, and no internal engine failure was identified. This failure appears consistent with a known defect pattern affecting GM 6.2L engines involving internal valvetrain or camshaft-related failures. …
Purchased a used (128k miles) 2019 Chevrolet Tahoe LT. First month of driving (not for everyday use) noticed some strange transmission and engine hesitations when reversing. Notified the dealership and was told the transmission needed reprogramming. They reprogrammed and the problem though less noticeable, still persisted. Contacted the local and the purchased dealership to let them know of the persistent issues. Purchase dealership had me bring the vehicle back where I was told the vehicle needed a new transmission. Vehicle had less than 600 miles since my purchase. I was told it was $10k and I was liable due to the expiration of the limited warranty.

6.2l Engine Failure: Vehicle was purchased last November at 113000 miles and at approximately 127000 miles we heard a noise coming from our engine one morning. Took it to the dealer we purchased the truck from because we bought an extended warranty and they got back to us and said there were metal flakes in our oil. They dove deeper and said it was connected to internal engine failure. They told us we could keep driving it but we said no that's too dangerous and current it's sat 3 weeks on their lot while we figure out what the warranty company is going to do and if we're going to be able to get a new motor from GM. I owe $40,000 on a car that is basically junk and idk what to do. When my dealer told me GM only put 21-24 in their recall I started digging and found out the entire L87 6.2 gas platform is plagued. …
