ENGINE
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.

ENGINE
My 2021 Chevy Silverado 3500 [XXX] Motor began requiring a quart of oil every 3-4 weeks. I took my vehicle to a GM dealer in October 2024 and the stated the couldn't find any issues. Fast forward to December 2024 my motor began reading low compression and saying stop the vehicle. I took the vehicle back and pressured them to find out whats wrong with the truck as I only have 76,000 miles and I have performed all of the necessary maintenance. I even have a Chevrolet Platinum protection plan for warranty coverage. I have gotten the run around for months and I have yet to get my vehicle repaired. After taking my truck to a certified 3rd party the verified that the lifters failed and the motor would likely need to be replaced or rebuilt. The mechanics reported this Information to the Chevrolet warranty company and the stated the refuse to provide and repairs unless I produce oil change receipts or return the vehicle back to a dealership and pay for the dealer to tear the motor down. PLEASE HELP ME!!! Im stuck paying $819 a month for a truck I haven't driven regularly since December 2024. Please please please help me Sincerely [XXX] General Motors [XXX] 2021 3500 hd wt 4x4 Case # 9-XXX [XXX] I have a 2021 chevy 3500 lt (dually) Been having issues with a rough idle so I figured to replace the plugs, coil packs and wires as my truck just hit 70,000 miles. After doing the full tune up nothing changed, so I scheduled an appointment with my local chevy dealership. They kept my truck for about a week and never completed the diagnosis. I picked the truck back up and took it to another chevy dealer and the told me after a week or so that I had lifter issues and the truck would probably need a new motor. The truck seemed a little sketchy from the gate in the first 50k miles it consumed oil like it was a ol 250k mile chevy.... the alternator went out at around 50k miles and the fuel efficiency would be 6-8 mpg at best.....

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.

My transmission started to make a rumbling sound intermittently while I was on the highway. It happened during normal highway speed and not dependent on acceleration or deceleration. I brought it to the dealership with 84,000 miles and they dropped the transmission pan. No metal found in the fluid. The issue was with the torque converter. I had my oil changed 1.5 weeks prior with a 21 point inspection. I was curious if there was a TSB for this issue. I haven't been able to find a recall notice for this issue.

POWER TRAIN
I experienced a locking up or no power to the rear wheels. It was raining and the rear wheels would spin. I had no traction. I had to take a few turns and had to be careful or I would have fishtailed into other vehicles. When I stopped at a stop light/or sign then proceeded forward the rear wheels would spin in place. The tires wouldn't grab the pavement. This is the best way I could explain it.
