| Nov 2024 | STRUCTURE | The contact owns a 2021 Chevrolet Silverado 1500. The contact became aware of a stain on the rear driver’s side interior of the roof of her vehicle and became aware that the source of the leak was the edge of the window. The vehicle was taken to a local dealer to be inspected, and the contact was informed that there would be no assistance with repairing the vehicle since the vehicle was out of warranty. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 25,900. | Crash: No Fire: No | 25,900 |
| Nov 2024 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | Vehicle attempted to do an 'over the air' update to the infotainment system. This prompted an error message, stating the update failed and return to the dealership. Took vehicle to GM dealer, diagnostics were run, and dealer stated that an update was not available, and the module for the infotainment system was bad. Quoted me $1600 for replacement and install. Have read multiple reports with owners' having the same issue. Infotainment system attempts to do an update, and it fails. The owners are left paying out of pocket for something that was not their fault. This needs to be a recall. Not only are you paying a hefty amount for a repair that is not your fault, but the entire Infotainment system doesn't not work (stereo, cooling/heating info, back up camera etc) | Crash: No Fire: No | Unknown |
| Nov 2024 | ENGINE | While driving down the highway on 11/03/2024, the engine warning light started to flash, I heard a clicking & Clanging noise so I pulled over as soon as I could find a safe place. Turned the ignition off & on again & engine warning light did not come back on, but still heard noises coming from engine. When driving home, the engine warning light came on again. I stopped again & turned the ignition off. When I turned it on again, the warning light quit flashing. I drove to the local GM dealer the next day, and they said it was a lifter problem. I did some research and found there were many lifter problems for a 2021 Silverado that I owned. I was hoping the dealer would replace both sides of lifters as they told me there was an issue & they were reengineered. Service department employee said they could only replace one side as that was all GM would approve. I told the employee that I did some research & there was a bulletin that said if mileage was less than 16,000 miles, both sides should be replaced. The employee said you surely have more miles than that & I showed her my odometer reading of 14,528. Again the employee told me that was all that GM would approve. I believe this is a safety issue if there is not a safe place to pull over. Also there should be a recall to replace these lifters with the reengineered lifters or extended warranty so us consumers are not stuck with a huge bill in the future as GM is aware this is a chronic problem. | Crash: No Fire: No | Unknown |
| Nov 2024 | POWER TRAIN | The contact owns a 2021 Chevrolet Silverado 1500.

The vehicle was not diagnosed or repaired. The contact later became aware that the VIN was included in NHTSA Campaign Number: 24V097000(Power Train), which the contact related to the failure; however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 106,000. VIN tool confirms parts not available. | Crash: No Fire: No | 106,000 |
| Nov 2024 | ELECTRICAL SYSTEM | The tailgate activates on its own, whether the truck is on or off, in motion or parked, the tailgate will activate and open at random times. There is no button that is pressed down, and no user error making this happen. When driving the vehicle, the tailgate will slam open and if you are pulling a trailer, the tailgate will slam into the trailer hitch and cause damage. Also, contents falling out of a truck bed is also a serious concern for other drivers. The truck was read for codes, and the code U0140 came up for the body control module that is malfunctioning. The truck has not been inspected by the manufacturer as of yet, but if need be, it can be arranged. The first time this error was noticed was in August 2024, and has been happening on & off since then. There were no dashboard lights on showing an issue was present when it first started and even now there are still no warning lights. Please consider issuing a recall, this is a major safety issue for other drivers. | Crash: No Fire: No | Unknown |

| Sep 2024 | STRUCTURE | The way I can best describe it is my vehicle falling apart, either due to cheap parts. Or poorly being put together. I was driving down the highway at about 65 miles an hour, when suddenly I hear something smack what seemed to be my headlight, then again snack into my drivers side mirror. I had not seen anything on the road previous to this or anything in the air so it seemed strange to have “hit” something. I was about an hour from my destination still so when I arrived I checked out my headlight. I then discovered I hadn’t hit anything, a piece of the fascia of my truck had blown off in the wind, which was the first sound I heard, then proceeded to impact my drivers side mirror. I’m not sure how long it was in the air or if it had impacted any vehicles on the highway behind me. | Crash: No Fire: No | Unknown |

| Sep 2024 | ELECTRICAL SYSTEM,ENGINE | Multiple times at varying speeds my 2021 Silverado has produced engine misfire codes. I have never been able to get to it quick enough to see what cylinders are misfiring so it always gives me a general P0300 code. The following first two times it was confirmed by Widrick truck and diesel in Carthage, NY. The last time it happened, the code disappeared before I would take it to the Chevy dealership. Widrick said they can’t fix the problem because they don’t know what it is, and Chevrolet denies there is a problem at all. The truck still has less than 50k miles on it | Crash: No Fire: No | Unknown |
| Sep 2024 | SERVICE BRAKES,ENGINE | I took my car to the dealership four times because the engine light and the ESC light kept coming on. It kept saying there was a misfire so they changed the spark plugs and did a gas treatment after I left the dealership the light came back on so I returned the next day. They change one wire that’s what they told me. The problem was so I left engine light came back on. I returned the next day then they changed the wires I left the facility again. The next day I got them started the car, the same problem, engine light, and the ESC light and now they have the car in the shop and they need to break the engine down to see what’s causing the misfire and to find out if I need a new engine or not. Who is all that shit right now? | Crash: No Fire: No | Unknown |
