When I initially started the vehicle, I noticed the parking assist would not turn on. No warning lights or messages were displayed so I didn't think much of it and continued on driving. Approximately 5 miles down the road while traveling around 45 mph, I came upon a stoplight with other cars waiting. I pressed the brake to start decelerating and the pedal went all the way to the floor and vehicle did not slow down/decelerate. The check engine light, ESC, trailer brake, and brakes warning lights/messages then illuminated. I was approaching the vehicle in front of me quickly so, to avoid a rear end collision, I swerved into the shoulder and was able to coast through a right turn and on to a side street where I eventually coasted to a stop. I narrowly missed a major collision and was fortunate that there was no cross traffic approaching when I turned on to the side street. …
I purchased my 2022 GMC SIERRA XLT in February of 2022. I have had it in the shop 4 times for recalls. They couldn't or didn't put an inspection sticker on the truck because I honestly don't think it could have passed inspection. The truck sounds like a truck on Transformer when I turn it off breaking town like a robot. On yesterday which was 1/27/2025 while backing up to turn around the truck started dragging in the back like the breaks locking up, the same thing happened while turning into my driveway off a state highway with an 18 wheeler coming. GMC can't look at the truck until February 10! This Truck was purchased new and it's been nothing but trouble. Electrical system goes in and out Steering assist reduced drive with care, Engine power reduced, park assist on then off and truck making unusual noise. …
The system that failed was the wire harness for the internal brake control. This is a well documented problem on YouTube and Reddit. I was driving home from the mountains, with my 7K lb camper, and I started receiving incessant messages alternating between "Trailer Brakes Disconnected" and "Trailer Brakes Connected". The messages made it impossible to see the speedometer and hear music or calls. Most importantly, I lost my trailer brakes in the mountains of North Carolina. Meaning the only way I could slow down was with my truck brakes, while a 7,000 lb camper was pushing me. I took my truck to the dealership today and paid $166 for a diagnostic. The stated the issue was with my camper. I tried to explain that many owners were having this problem and it is well documented. They stated there was no recall on my vehicle and gave me a print out of what to check on my camper. …
Reference GMC PIT5948A : Service Trailer Brake Message with DTC C159C - October 6, 2022. When I connect my trailer that has trailer brakes the system recognizes my trailer and the trailer brakes work until I try to drive. I get an error message "Trailer Brakes Disabled Service Trailer Brake System". This may happen within a few feet or the longest is about a mile. GMC has no fix and the dealer while cooperative didn't/couldn't trouble shoot the problem as the above PIT has no known corrective action. Now I own a truck that has the "Max Trailer Package" that is rated to pull 13000 lbs but has no trailer brakes. I have eliminated my new trailer as the source of the problem by making a Trailer Brake Emulator, see PIT #5509H Diagnostic Tip. The error continues to happen. This puts myself and the public at risk if the trailer is heavily loaded.
