| 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 | STRUCTURE | The tailgate on my 2021 Chevrolet Silverado 1500 opens randomly. Initially, it was not often, but progressively happening. I had to pull over in rush hour traffic this morning to shut the tailgate after it opened randomly. The only reason I knew, was checking the rear camera. | Crash: No Fire: No | Unknown |
| Sep 2024 | POWER TRAIN,ELECTRICAL SYSTEM,ENGINE | Lifter failure of the right bank in 2021 at 19,000 miles. At the time of failure engine was 2.5 quarts low on oil. Ever since, this truck has been using oil excessively. I am currently involved with an oil consumption test. Of which over the last 5k miles I have had to have more oil added by the dealership. | 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 |
| 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 |

| Aug 2024 | POWER TRAIN,ELECTRICAL SYSTEM,ENGINE | When you drive the truck for at least an hour then you turn it off the entire front like vibrates or shakes . It almost feels like something is still turning in the transmission but everything is turned off. This particular truck has already had the engine replaced at 14,000 miles bc it was faulty. It also has issues with tires. The radio and lights also all go off for brief time and then it comes back on. At times the drives side seat belt will lock and it pins you to the seat where you cannot move and you have to remove the seat belt. It is becoming more of an issue. I believe the transmission to be going out. Today, I wasn’t sure if the vibration in the truck was going to stop. So I stopped driving the truck and went and got another vehicle to drive | Crash: No Fire: No | Unknown |
| Jul 2024 | POWER TRAIN,UNKNOWN OR OTHER | Heard and felt a loud clunk from underneath truck while driving 70 mph on interstate. Pulled off and next available exit with a hotel and parked truck. Cranked truck to move and it would not move forward or backward except for about a foot. Loud grinding noise. Had to call tow truck to tow us to nearest Chevrolet dealer. Dealer service department says transfer case has seized up and must be replaced. Transfer case is currently on backorder and not available from GM. Was given rental car to drive home, which is 10 hours away. Truck has been in shop for 7 days as for this writing and I still do not have an answer about when a transfer case will be available and they can repair my truck. I located transfer case at my local dealer but repair dealer says they have to wait on GM. | Crash: No Fire: No | Unknown |
| Jul 2024 | POWER TRAIN | While accelerating moderately, the transmission downshifted and momentarily locked up the read axle. This caused the rear of the truck to start sliding out.

I am glad I was not pulling a trailer at this time. I reported this incident to my Chevy dealer and informed them of the existing service bulletin on this exact issue. 21-NA-275. The dealer has not followed up with me on their conclusion or what they will do about this dangerous defect. No warning lamps, messages, or other symptoms before this incident. | Crash: No Fire: No | Unknown |
