Our tailgate would open on its own intermittingly. We haul our fifth wheel camper and this could cause damage to the RV and our vehicle. There have been recalls on one year older trucks and one year newer but not for the 2021Chevrolet Silverado. A Chevrolet dearlership in Florida looked at it for us. They said cause : checked for codes and bulletins. Found code B153D. Completed circuit check. Also found tailgate hatch out of adjustment. Corrctionj: Rec. replace switch and adjust latch. We were charged $486.05 for this. We feel this should be a recall problem. Please advise.

Tailgate opens by itself. This happened 3 times in 2 hours while the vehicle was parked. I tow a 5th-wheel trailer. If this happens when towing it can cause a catastrophe.

Injector #4 connector harness issue- Known issue on the 6.6L duramax. Driving with my children for Christmas pickup and power reduction occurred while passing another car on the road. Causing us to hit the breaks as the truck wouldn’t allow us to pass timely. Known harness issue by GM and instead of covering I had to pay to have a new connector spliced in. Multiple warning lights. Check engine, Emissions warning, Reduced power, Traction control, parking brake

Driving home from work 7/1/2024 approx 5:15PM Smelled burning smell, no noise or dash lights, thought it was another car. 1 minute later, heard a thump from under hood and "Charging System Failure" came on dash. Decided to take to Chevy dealer, which was 5 minutes away. Within next 2 minutes steering failed. As I came to next intersection, brakes failed, went thorough red light, luckily not hit by another vehicle. Coasted to stop and called tow service.Engine was still running until I turned it off. Had towed to local Chevy dealer. AC compressor had locked up, broken belt. Steering and brakes failed. Dealer agreed both failed, but would not list the brake failure on the invoice. I was originally invoiced 2900.00 to repair, even though truck had only 29244 miles. That was reduced to 1160.00. Was told it was 2 months past 36 month warranty. Engine was still under warranty, but AC, alternator, power steering and brakes, was not,. I had contacted GM which originally told me they would reimburse me for repairs and would mail me a check, I have the email. When check did not arrive after 2 months, I contacted my case worker again via email and phone. Could not get a response after about 6 attempts. When I called and finally got another person, I was informed they had changed their mind.

Electrical components are failing in the tailgate lock/unlock mechanism. The tailgate goes up and down on its own while in park. It will also go up and down on its own after the truck is off and unattended This started happening about a week ago. It is available for inspection upon request and has not been inspected by any agency yet. The tailgate could damage itself or other property randomly. It could also impact someone standing near it causing injury. There is a service appointment scheduled 3 days from now. There were no symptoms or warnings of a problem. The Chevy App actually says that all systems are ok.
