2019 Chevrolet Tahoe Engine

2019 Tahoe Chevrolet purchased in October 2025 and engine locked up in January 2026 when Engine Valve Lifter went out. I kept car serviced. Went to start vehicle one morning and it started making the loudest noise as if it had bad gas. Found out lifter was gone out and locked the engine.

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. The failure resulted in abnormal engine noise, misfire, loss of power, and the vehicle becoming unreliable for safe operation. General Motors has declined goodwill assistance citing warranty expiration, despite the nature of the failure being a non-wear internal engine defect. I am submitting this complaint so this VIN and failure can be reviewed as part of any ongoing investigation into 6.2L engine failures.

I also had this issue with my prior gmc 2017 yukon until i traded it in.. My currently 2019 chevy tahoe premier has always had services done when required with milage needed. My issue While driving viechle on freeway knocking with shaking sound in engine. Engine light would turn on. Even though with tune-ups oil changes done this problem still continued. Now my car is sitting on driveway and cant drive it

Loss of power

The 2019 Chevy Tahoe at 92000 miles is having lifter problems and a failing engine due to the DFM system. This is a 5.3L V8.

On 10/23/24 the vehicle's 6.2 L L87 engine seized while driving on a state highway (similar to the later models already under recall) putting myself and other drivers at risk through a sudden loss of power and speed. The component was inspected at a GM dealership and then replaced AT MY COST. The replacing mechanic said the failure was in the rod bearings (the same as in the recalled engines). There were no warnings or related problems prior to the sudden failure. The existing recall ( Investigation:PE25001) needs to be expanded to these earlier model (2019 and 2020) engines that have the exact same issue.

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. Let them know these issues were identified and not fixed during the warranty period. Dealers fixed the vehicle but still charged me almost $4k. With the new transmission in place, I still noticed an engine hesitation, as if it was missing. Had new plugs installed but still no luck. Was told that cylinder deactivation may have caused lifter issues. Took it to my local dealer and thought the issue was obvious, they said they couldn’t find the issue. I was charged $300 for a non diagnosis or fix. The issue still persist

MY VEHICLE IDLING IS MISSING I ASK DEALER TO CHECK IT WHEN I RECENTLY HAD OIL CHANGE. DEALER REPORTS BAD MOTOR MOUNTS REQUIRING MOTOR AND TRANSMISSION REMOVAL. I HAVE A NEW VEHICLE YET IT NEEDS MAJOR REPAIR.
