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.

The contact owns a 2019 Chevrolet Tahoe. The contact stated that the vehicle was consuming an excessive amount of engine oil. While driving at 30 MPH, the vehicle stalled consistently while shifting gears. There were no warning lights illuminated. Upon investigation, the contact linked the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The vehicle was taken to three independent mechanic,s who indicated that the failure was related to the engine. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 120,000.

Loss of power

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

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.

Active Fuel Management for the automobile variable displacement technology was the issue. 6.2L V8 L87 engine has created the following issues- Cylinder deactivation issues transmission issues Multiple camshaft issues include camshaft lift issues Fuel system problems

Valve lifter issue. Gm service told me 15000 engine replace. 1 year no used the vehicle. I buy the vehicle 35000. no recall or warranty. Have to much people this problem. And a gm just laughing at how the vehicle owners behaved.

Not power, lot blue smoke, excessive consumption of engine oil, noise in the motor, like something is broken in it.

Lot white smoke for tail pipe, noise came in the motor, leak gas for tailpipe

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

Vehicle will stall while parked causing a strong odor of gasoline. Takes several minutes of sitting with vehicle off before it will start again. The vehicle has also done this while coming to a stop. This vehicle has 41000 miles on it and continues to do this. It is used for law enforcement agency. I am required to respond to calls and this hinders response times to calls as well as emergent responses. The dealership has looked at the issue and blamed it on fuel having water in the fuel. They have replaced several items involving the fuel system. This has not solved the problem. Bob Ruwarts has not given an answer.

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.
