The contact owns a 2018 GMC Sierra 1500. The contact stated while driving approximately 70 MPH, the trailer wiring harness system warning message was illuminated. The vehicle was taken to a local dealer where it was diagnosed with needing the wiring harness replaced; however, the vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 77,000.
At 50,000 miles the "service trailer brake system" error message appears constantly due to factory defects and its very common. These trucks should be recalled everyone is in danger on the roads and its a very common problem. I have not taken it to the dealer because i should not have to pay for this very common problem, it should be recalled.
The truck displayed warning lights for ABS, traction control, trailer brakes, and front park assist. Additionally speed control (cruise) did not function. This presented a safety issue. I took to dealer asap. They repaired by replacing left rear wheel speed sensor. Cost about $216. Appears to work correctly at this time.
Battery dies after 5days of not being driven. Battery continues to go dead, dealer states nothing is wrong. No repairs were made. Stranded 5 times with a dead battery

The first thing that happened was that all of the electrical systems on my truck went out and my truck would not start. It finally started but it would not move finally it would move but very slowly this happened on 11/20/2019 I have documentation through onstar for this incident. My brakes started slipping on 07/01/2020 and still do not work properly. My transmission has never shifted correctly. When I accelerate or when I slow down there is a shudder and a jerking sound. After sitting for a while when my truck is put in reverse it hesitates and then seems to jump into gear.
My truck locked itself with the engine running when I was parked in the driveway. Also have had the back driver side window roll itself down part ways without me initiating it. Another occasion I put the truck in gear to drive position and the brake or something had it locked preventing me from moving either direction ie; drive or reverse. Was then parked in home garage and attempting to back out.
My vehicle is hacked anytime I am driving the vehicle I am not in full control. The vehicle steers itself left or right while driving, the brakes are always on while driving sometimes braking harder but always on. The infotainment system has many glitches. This vehicle has been back to the dealership more than 15 times has been out of service over 35 days GM even flew a engineer/tech to inspect the vehicle and says they couldnt find anything. Therefore this vehicle is hacked there are so many issues and glitches and the fact that the truck only acts like this when I am driving no one else. Like it can be turned on and off instantly. I have tons of videos pictures and supporting documents backing this. I need help this is a serious issue and there is so much more to it than I can type here someone please get ahold of me to help or point me in the right direction. This vehicle will be returned to GM soon as they are doing a vehicle replacment per all the issues but this needs further attention because if this can happen to me it can happen to anyone. Please help
