Losing power while driving and acceleration and uneven idle sometimes

The Vehicle that I own is a 2021 Chevrolet Silverado 1500 with a 6.2 liter engine. on 6/2/2025 i went to have the oil changed and the service technician informed me there was no oil in the engine. He also informed me that this particular model with the 6.2 liter engine had a recall relating to components in the engine. After researching I found that there was in fact a recall, but my truck was not listed on the NHTSA web site. I made a visit to the local dealership and the service manager informed me that there was in fact a recall but there was nothing they could do at this time. He suggested that I check the oil level every 500 miles and wait on a recall notice. Now the engine is starting to make internal noises that concern me greatly. There is a opportunity that the engine could simply lock up and there is no certainty on what might happen. Please advise

The 6.2 is using 1-1.5 QT. every 3000 or so miles. I have done the check every 1000 miles. Had a bent lifter replaced 2 christmas ago.

My truck was brought in for the recall inspection for the 6.2 lt recall. After showing the dealer pictures from the oil that drained out of my previous oil change that was filled with metal, they expedited the inspection. But with substantial amount of metal in the oil filter the truck still passed the test. GM corporate has told me that once the inspection is done, it is out of their hands and that my truck will be covered under the new extended warranty. GM also should have the pictures of the metal flakes from the previous filter. I fill like this is a failure to ensure the safety of their product. I do not fill safe having my children or my wife in the truck due to the inevitable of the engine loosing power due to the faulty cam shafts that need to be replaced.

Vehicle experienced engine failure while driving. Loss of power in traffic. Inspected by dealer and determined to have lost compression in cylinder #5. Initial inspection determined that lifters and camshaft would need to be replaced. This issue is the same common problem with this year model (2021) Chevy Silverado Trucks as noted in TSB #N212353840. At time of purchase dealer did not notify me that these trucks were experiencing these issues nor did they complete the suggest repairs prior to the sell as described in the TSB.

engine is knocking very bad. GM Dealer says it is an issue w/ the piston main bearing and the engine needs to be replaced. Says vehicle should not be driven.

My engine on my 2021 Silverado 1500 with the 6.2L L87 engine failed, I took it to the dealer to repair and they quoted $4500 to fix it. I know these same engines are being recalled and GM is having to replace them, but they told me mines not one of the ones being recalled and the won't cover it because the warranty was up 5,000 miles ago. I highly doubt it's a coincidence, that mine failed after only 65,000 miles and it's not a manufacturer flaw. The vehicle is currently at the dealership awaiting repairs.

Driving to work my engine failure light came on….the engine immediately sputtered. I immediately drove inside the bay at Ozark Chevrolet. As soon as I pulled in….the technician told me to turn it off and that I wouldn’t be driving it anymore. See my statement for $3,429.15. I have to carry my grandkids in this vehicle. I traded it in on Tundra. And now I find out about the recall. It was the 8cyl engine currently under recall.

I’ve purchased my Chevy Silverado brand new and I’ve had to bring it to the dealership multiple times for code P1098 this will be the second time this has been repaired. Looking on line this is very common. This is the second time I have to leave my vehicle at the dealership and not I don’t have my vehicle.

Like many others, I have been dealing with many issues with this truck. I have had repeated cooling valve failures, resulting in decreased engine power and constant cooling fan running at high speeds. Additionally, cranking issues with starting the vehicle.

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.

We have a 2021 Chevy Silverado 1500 in which the engine has failed. We believe this is the issue involved in the recall of Chevy Trucks. It needs to be added to the recall list. It has been unable to move since 2/17/2024. We have reported this to GM but they have not responded. Thank you
