2021 CHEVROLET SILVERADO 1500 Complaints

On 4/19/24 I was driving at highway speed. The engine started to knock and the check engine light came on. I was fortunate enough to be extremely close to my local Chevrolet dealership and made it there before the engine failed. The truck had 38633 miles on it. They found damaged engine components and repaired only the broken parts. Was under warranty. Truck is still ticking to this day. Took it in for this noise and they said nothing was wrong.

1- Tailgate keeps opening by itself. It has opened while driving down the highway and things fell out of back of my truck almost causing an accident. It has opened while sitting in my driveway after I have turned the truck off and gone inside. I have reported this to a dealer they said my vin is not on the recall list. I would like my VIN added since it is obviously an issue with the Silverado's. 2- I recently has to bring my truck to the dealer for the transfer case sounding like there were bolts in a blended and a pinging sound by the bell housing while in park. They stated it was the front axle and fixed it saying it was a power train thing. The noise is back and now out of warranty.

Complete engine failure and it just outside the recall. This is unacceptable and needs fixed.

The contact owns a 2021 Chevrolet Silverado 1500. While the contact's wife was driving at an undisclosed speed, the engine seized. The low engine power warning light was illuminated. The vehicle was towed to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine failure was the result of no oil in the vehicle. The contact was informed that there was no oil on the dipstick when checked. The contact stated that the failure had occurred shortly after an oil change was performed on September 9, 2025, at Walmart. In addition, the contact stated that there was no evidence of an oil leak. The contact was informed that the engine needed to be replaced. The vehicle was repaired. The contact referenced an unknown recall with a similar failure description; however, the VIN was not associated. The manufacturer was not made aware of the failure. The failure mileage was approximately 62,248.

Not sure of exact date I believe it was right before Thanksgiving. The truck started shuttering and vibrating. It feels like we are driving on a gravel road. the manual said to change transmission fluid between 45,000 and 60,000 so we took it to the dealer. that is what we did hoping that would fix the problem. but it did not so we took it back and they kept it for 3 weeks they said no codes came up and they said the tires needed balancing so we let them do that but the problem is still there. they say there is no recall on it . we did some research and found information stating Chevy is having problems with the transmission. as of now we only have 45,608 miles on it. It is riding worse now.

I have a Chevrolet Silverado 1500 with the 6.2L engine. I received the recall notice about the loss of propulsion due to a crankshaft issue. The safety of myself, family, friends and coworkers who ride with me on an everyday basis were put at risk because of the faulty engine. I brought my truck in for an oil change in August 2025. I had the Team Chevrolet dealership in Las Vegas Nevada do a telescopic inspection to see if my particular engine had the recall issue. It was discovered the engine did have the recall issue and was kept by the dealership for roughly two and a half months. Chevrolet has confirmed this is a major issue and is affecting roughly 600,000 people. There was no sign of the issue before the telescopic inspection but since the engine has been replaced I have now had three separate issues with misfiring cylinders on the new engine. The plugs and wires have been replaced twice and has not resolved the issue. When the misfires have occurred there were error codes, check engine light notification, and engine sputtering. This again has endangered the safety of myself, family members, friends, and coworkers who ride in my truck on a daily basis. This is now going on four months of issues that keep persisting and I am very concerned that both the manufacturer Chevrolet and the Team Chevrolet dealership are not taking the proper steps in order to solve this very serious issue.
