2023 GMC CANYON Steering Problems

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.

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...
