Tailgate. Yes it can be inspected. It opens and closes randomly , I was going on to the freeway for work when I suddenly received a notice that the tailgate was opening. when I pulled over the gate was open and all the contents were at the end of the truck bed, power saws and equipment almost flew out into traffic! I then called the dealer who told me there was a recall and to bring it in, so I did and when I pulled in the service department the tailgate opened upon entering service area. After about 20 minutes he tells me that mine is not covered. Warranty ran out! And not on that Vin#. The tailgate now opens and closes randomly at all different times.Try to close and it just keeps opening and closing.Have to go out and close manually.

Having issues with “Service Trailer Brake System “ , this should be a safety concern for GM , and not up to the customer to pay for this repair.
It's a known issue that 2020 and 2021 Chevy Silverados have a malfunction in the tailgate where it automatically opens while driving, opening the driver-side door, or even locking and unlocking the vehicle.
2021, Chevrolet Silverado 2500 HD, Crew-Cab, 6.6L Gas Engine. At @ 25k miles, the "Service 4WD" light came on dash. It later started a grinding noise/sound within the front axle transfer case. Was told they had a problem with moisture intrusion into the transfer case and it would cause corrosion to sensor. Truck was taken to dealership and in shop for @ 1 week or so. After repair was completed, less than 3k miles later, it happened again. Same problem ("Service 4WD"), same noises, same diagnoses. Truck was taken back to the dealership. This time, repairs were more extensive and the wiring harness was replaced. I was traveling with work yesterday (34,458 miles on truck now) and the "Service 4WD" light came on again. I've contacted the dealership to schedule a time at the end of week or early Saturday to take the truck back again. While reviewing other complaints, I noticed a similar problem where the customer indicated the "Service Tow System" light was coming on. It too was allegedly caused from moisture intrusion. I'm currently over 3 hours from home through the end of the week. I'm hoping the truck will make it home without creating a catastrophe on the Interstate between here and there.
The “Service Trailer Brake System” warning will not stop popping up and beeping
After two weeks of ownership, the rear camera has stopped working. Instead, I receive an error message. There are no shortage of complaints like this on various model chevrolet forums. Most 2020/2021 customers indicating there has not been resolution or specific issue identified.
6.6l gas truck would not start. Forums ive visited state this is a known problem with the ECM. After approx 30mins it started. However before that it sputtered out every time I would try to start it. It appears to be an intermittent problem. It ran fine once it eventually did start. Also auto start wouldn't engage when this problem was occurring.
