“On at least 5 occasions, my inner tailgate has released itself and gone down during motion. This has been uncommanded. It appears GM has a recall for this but it does not include my truck. The dealership that looked into it agrees this is likely the same issue and GM should include it in the recall.”
NHTSA complaint #11622341, filed 2024-10“Vehicle caught fire minutes after remote starting. Fire appears to have started on firewall on the left side. We were about to take our kids to school vehicle could have easily caught our house and other property on fire. We did have the check engine light come on occasionally but it would always turn back off, vehicle only had about 12000 miles. Also none of the outlets inside the vehicle never worked.”
NHTSA complaint #11580555, filed 2024-04“The in cab brake controller does not work with electric over hydraulic trailer brakes. In my research to diagnose and fix the problem I find out GMC has known about this for years and has done nothing to correct. I pulled code C1114 and GMC issued a bulletin for part number (K58-036-00) which I purchased and still did not correct this issue. In short there are many 3500 trucks out there running with no trailer brakes. Here is the worst of this problem. …”

On 3/3/2024 I was preparing to wash my truck and noticed my front amber lights were on surrounding my headlights. the vehicle was off, and my keys were in the house.
