general problems of the 2016 GMC Sierra 2500

Trailer brake system continues to pop up “service. ”.

I am receiving an on-and-off “service trailer brake system” when towing and sometimes when not towing. Checked every component and alert does not stop. When this happens while I’m towing, trailer brakes stop working momentarily.

Service trailer brake system warning over amd over.

Brakes make a noise when I brake. I am only going about 25 miles and press on brake the brakes don't seem to stop right. There's a ticking noise coming from the engine or brakes.

I keep getting a warning message "service trailer brake system". The warning may come on for a second or it may stay on for 10 to 15 minutes. It may do it once a month or 10 times in a 2 minute period. Whenever this happens I lose the electrical braking system on what I am towing. There is no set pattern or circumstance for when or how long it will happen. I was told if the alert is not on there is not a way to diagnose the problem and since I never know when it will happen I cannot schedule any type of diagnostic service. It does seem to happen more often when it is raining but has happened in perfect weather too. The warning has occurred both when I am towing and when I am not. I've done searches for possible causes and it seems to be a common problem. I regularly tow a 12,000 lb. Fifth wheel RV with my family. I cannot afford to lose my ability to stop in a reasonable amount of time. I simply cannot do it when I lose my trailer braking system. The date below is the last incident.

While driving at 45mph in the left lane of a major city thoroughfare the engine quit running, power steering and brakes did not work. The check engine light came on when the engine quit running. I was able to get the vehicle stopped but the engine would not start. The vehicle was towed to the dealership where I was told this issue was reported in arkansas, louisiana and tennessee. The dealership reported that shards of metal were found in the fuel injector and the entire fuel system would have to be completely replaced. Additionally I was told the parts are hard to get. The vehicle was purchased new and was 7 months old and had just over 7,000 miles. The vehicle is still sitting at the dealership 10 days later and has not been moved from where it was delivered by the wrecker service. Gm has been notified but no response from gm or dealership management yet as to what caused the engine failure. I occasionally tow a fifth-wheel RV with this vehicle. I no longer feel safe driving the vehicle and would not consider purchasing another until a determination is made on exactly what went wrong.

The contact owns a 2016 GMC Sierra 2500. The contact stated while driving at an undisclosed speed four years ago, the steering wheel became significantly loose, causing the contact to lose control of the vehicle. There were no warning lights illuminated. The contact depressed the brake pedal and veered to the side of the road. The contact then continued to drive at slower speed and away from other vehicles. The vehicle was taken to the dealer and was repaired under technical service bulletin number: pit 5501f; however, after the repair, the front-end of the vehicle and the steering wheel would wobble while depressing the brake pedal. Additionally, the contact stated that the steering wheel failure reoccurred several months ago while driving. Upon inspecting the vehicle, the contact removed the driver's side wheel cover and discovered that the brake fluid had been leaking inside the wheel well and underneath the floorboard under the steering column. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 4,450.
