What owners report

From a complete stop the car suddenly accelerated as if I had floored the gas pedal. I braked hard and brought the car to a stop, the engine still racing. I turned off the engine, waited a while and restarted the car. Normal operation. I was too far for a tow, so I drove ~50 miles to my daughter's house.
