I was stopped at a stop light and all of a sudden, the engine just revved amd revved and no drive only reverse, and it happened 4 times until tonight, 11/11/25 @ 8:38pm I am stuck at another red light and have to back my truck up to Home Depot and get a tow. Only a 5 year old truck with 71122 miles and ALWAYS WELL MAINTAINED WITH PAPERS AND GOES OUT ON ME. NOT ACCEPTABLE GM! You make things and used to be solid, like a rock trucks but now I feel robbed as a long time Chevy fan/enthusiast but I may have to change manufacturers unfortunately.

GM 6.2 engine recently tested for the national recall regarding valve and lifter issues. Recall was cleared as ok, but they found burnt cylinders in multiple areas within the engines. Several issues are still occurring with this engine, and I think most are related to the recall effort. 1. Engine will use oil at an abnormal pace when towing anything heavy. Recently used an additional 2 quarts of oil when towing a trailer that weighed 10, 000 pounds over 1600 miles. 2. Recently engine seemed to lose compression at a stop light and turned off. This happened an additional 5 times until I could get the truck off the road and into a safe place. The engine would immediately start and then die within 5-10 seconds. Towed to a Chevrolet dealership and the service manager tried to move it into the bay for diagnostic testing. started and stopped 4 additional times as they attempted to drive if 100 feet into the service bay. Towed to my hometown dealer that afternoon for diagnostics testing. The next morning when they started the truck it cranked fine and has been running since (7 days). No lights appeared on the dash during the breakdown or warnings appeared in their testing I have spoken to several other Chevrolet owners about the 6.2 engine issues and what was occurring with my truck They also had seen an increase in oil usage when towing heavy. I believe that your investigation needs to delve further into not only issues with the lifter / rods but also into other mechanical concerns that are oil dependent and related such as burnt cylinders. This last issue occurred on October 27, 2025.

Vehicle was at a stoplight with the auto start button engaged on it. The vehicle completely stalled. All the power is drained from the car. leaving me stranded in the highway. I got it towed and when replacing the battery still nothing will roll over or even turn on.

The truck started to vibrate badly. Brought it to the dealership and have to replace the 6.2 L engine. I was happy to make it home without it breaking down. The truck only has 67,000 miles on it.

Engine just died going 55 mph on a paved road. GM repair shop says engine needs to replaced. They originally told me my 6.2L engine was a recall, but my VIN didn’t show on database. Seems GM’s scope was not wide enough on their recall. I feel I deserve a new engine.
