| Vehicle Speed Control 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. 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.
