On August 11, 2025, at about 2:52pm, my vehicle was at a complete stop at an intersection awaiting the traffic light to turn green. There was a slight downgrade slope towards the intersection. The vehicle one-pedal driving was enabled. Weather was sunny with no wind or rain. Suddenly, the vehicle started vibrating violently and started rolling into the intersection. I pressed on the brake pedal but the vehicle continued to vibrate and the vehicle rolled into the middle of the adjoining lane of traffic. There was no traffic on the roadway and no other vehicles were affected. My vehicle had come to a compete stop in the roadway and I attempted to accelerate through the intersection but the vehicle would not move. I recycled the power to the vehicle and placed the vehicle into drive and proceeded to drive through the intersection. I do recall that when I was pressing the brake pedal, the vibration felt somewhat similar to vibration of the ABS brake system when the tires are losing traction but the vibration was much more pronounced. I pulled the vehicle onto the side of the road and checked the driver information display. A "Service ESC" notification appeared on the driver information panel followed by "One-Pedal Driving Unavailable Use Brake for Stopping". No other warnings or notifications were observed after this incident and the vehicle seems to be driving normally. I was able to re-enable the one-pedal driving mode the next morning.
