| Jan 2026 | POWER TRAIN,ELECTRICAL SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Jan 2026 | ENGINE | Complete engine failure and it just outside the recall. This is unacceptable and needs fixed. | Crash: No Fire: No | Unknown |

| Jan 2026 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |

| Jan 2026 | ENGINE | 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. | Crash: No Fire: No | Unknown |

| Jan 2026 | POWER TRAIN,ENGINE | 2021 Silverado 19,000 miles no indication of failure at a busy intersection about to go thru intersection and engines started knocking, multiple check engine lights on. Luckily got thru the intersection and to my place of residence which was very close by. Truck was towed to Chevy dealer. Dealer found 3 bent push rods, 3 bad valves. This engine had the lifters fail completely out of the blue. Oil changed at the dealer, meticulously maintained. Dealer only replaced the faulty bank of lifters due to mileage, seriously if it was under 16,000 they would replace all of them. This is unacceptable. This truck left me almost stranded in a busy intersection, lucky I knew well enough to keep going versus getting T-boned. I just think GM needs to do something about this. Now fast forward to 41K and I'm at the dealer same symptoms except this time my warranty is running up soon and being forced into an extended warranty. There are plenty of online claims, chat rooms, posts, etc to warrant this as a safety issue. | Crash: No Fire: No | Unknown |
