“The forward collission system continues to perform phantom braking while driving in traffic resulting in near rear end collisions. The GMC dealer refuses to fix it without charging me for more diagnostic work, which has already been done twice. What is my recourse?”
NHTSA complaint #11735981, filed 2026-05“While driving my check engine light came on indicating that service was needed on the Electronic Stability Control (ESC), traction control, Anti-Lock Brake System (ABS), brake assist the vehicle top speed reduced to 43mph. My braking system was compromised and I have to travel at reduced speeds on busy roadways to arrive at my destinations. I have taken the vehicle to a certified GMC technician for diagnostics and repair.”

Traffic was fairly steady and heavy, so we were traveling at approximately 45 MPH, in the right lane, winding through the mountains. Our friend, ** ***** was driving, my wife, ********* *****, was sitting in the right front passenger seat, working on her laptop, and I was sitting immediately behind her, also working on my laptop. …”
NHTSA complaint #11449744, filed 2022-02“Driving down the interstate at 70mph and it randomly slams on the brakes. At about 45mph it let's loose and speeds back up. There's never anything in front of the car and it does it a few times a week. Usually throws everything on the floor that was on the seats and scares the hell out of anyone inside the vehicle. Waiting for it to do it with a semi behind us that can't stop as fast!”
NHTSA complaint #11561007, filed 2023-12“The contact owns a 2021 GMC Yukon XL.
