2023 GMC Sierra 1500 brakes complaints
Page 2 of 2: complaints 11 to 17 of 17, newest first, as owners wrote them.
While driving on the highway a message came up stating Brake System Failure, top speed 62 mph. It also came up with other error messages, like service traction control. I completely lost any braking capability and had to let it slow down & pull off to the side of the highway. I shutoff the vehicle and then restarted it & everything seemed fine. I took it to the dealership right away, where they said it had about 20 communication codes across different systems. After 3 days of them having it, they have no idea what is going on. They are now test driving my truck to see if they can get it to happen again (which could kill someone if it does happen again).
I have been trying since day one of my brand new 2023 Sierra Denali pickup truck hence I spent a $100 K plus OEM accessories at the dealer ! This complaint is in reference to the safety part of the brake trailing that disconnect and lose light and brakes ! I have Spent insane times at the dealers and have complained to the GMC Executive offices with Nothing but excuses and Absolutely Zero Help from GMC Cooperate but continue to go make appointments at the dealers ! This is Safety complaint and they are not taking this seriously at all ! There is defiantly a ongoing issue with either the computer onboard or the trailer Module ! I am not a engineer but again this is a safety Issue that needs to be looked at ASAP ! I do not feel safe driving the truck !
Pulled up to a stop sign and attempt to make a right turn as I was in the turn the steering wheel locked up in the turn which almost caused and accident . I had to get the vehicle towed to Wyatt Johnson GMC dealership in Clarksville TN. I purchased this truck in Jan 2024 from Romain Cross Pointe Auto Park in Evansville ,Indiana at 7600 E Division St, Evansville, IN 47715 it had 13k miles. I'm the second owner I only put 2k miles since ownership. I was able to obtain a vehicle history report which shows this has been an on going problem among other issues DTC code U0131 Lost communication with Power steering Module shows at least 9 times that Romain GMC try to fix the problem. This is extremely dangerous to drive and the steering goes out this has been a known problem.. See attachments
The truck jolts forward when approaching a complete stop. I have to prepare for it as I decelerate 10mph to 5mph to complete stop.
Traveling at 70 mph on cruise control, tapped breaks to turn off, multiple warning lights flashed, vehicle lost power, and breaks with multiple messages including “Break system failure, top speed 62 mph”. I lost all breaking control on the highway and nearly crashed into other vehicles due to inability to stop. Was able to pull over, turn off vehicle, and turn back on, when the breaks were working again but the vehicles acceleration was very slow. Currently at authorized repair shop. When dropped off, there were 8-9 active codes.
