While driving on the freeway the car started accelerating on its own. Tried pumping the gas pedal to release it, car still accelerated. Brakes did little good. Was able to down shift into first gear, then into neutral and utilizing the emergency brake was able to get the car slowed down enough to cut the engine. Some problem happened immediately when I turned the car back on trying to get it off the freeway off ramp. Was able to stop safely in a parking lot without hitting anything. Had the car towed to the dealership, where they said it was a problem with the throttle.

The contact owns a 2005 Hyundai Sonata. The contact stated that when shifting into park while driving at any speed, the engine rpms would increase abnormally as the vehicle would independently accelerate. The failure recurred intermittently. The contact shifted into neutral to coast to the shoulder. The engine was shut off and when restarted, the vehicle returned to normal function. The vehicle was taken to a mechanic, who performed a diagnostic but was unable to locate a failure code. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure and the current mileage was 184,000.
