While driving at 70–75 mph on an interstate, my vehicle suddenly displayed a “Brake Failure” warning and limited speed to 62 mph. Power steering failed completely, and braking became ineffective despite hard pedal pressure. Multiple warnings followed: ABS, engine, and others. I was in heavy traffic with vehicles at full speed. Loss of braking and steering control forced me to coast across lanes to the shoulder, narrowly avoiding collision. My safety and that of others was at extreme risk. After stopping, I turned the vehicle off for ~30 seconds. Upon restart, all systems returned to normal—no warnings or issues. This indicates a transient software malfunction, not mechanical failure. No prior warnings or symptoms occurred. The problem has not been reproduced or confirmed by a dealer/service center. I have not scanned or inspected the vehicle. It has not been examined by the manufacturer, police, or insurance. The vehicle is in my possession and available for inspection upon request.

Since I purchased the vehicle it’s had the issue of it braking on its own. I brought this up to GMC many times. At the beginning they had me try to duplicate it with them, which I thought would be unsafe. They only acknowledged the problem and attempted repairs after I contacted GMC directly. The issue with the crash alerts while driving always stayed, even though there was nothing in front of me. Just recently it started braking on its own again in traffic. This has caused bodily and property damage, luckily nothing grave. I do not feel safe in the vehicle and gave gmc many attempts at fixing such a serious issue. I want them to tow replace the vehicle and provide a loaner. Please contact me if you need more details.
