While driving on u. S. Highway 270 in arkansas this date, my 2009 Jeep grand Cherokee experienced sudden unintended acceleration. I was pressing slightly on the accelerator pedal while going up a hill when the engine went into a wide open throttle condition. I was able to maintain control of the vehicle and turned-off the ignition, allowing the vehicle to coast down to approximately 45 mph. Upon turning the ignition back to "on" the vehicle again experienced sua and accelerated quickly to 60+ mph. I again turned the ignition switch to the "off" position and allowed the vehicle to coast back down. Upon turning the ignition back to "on", the engine went back into a wide open throttle condition again. After four tries (turning ignition "off", then "on", the engine rpm returned to a normal operating condition and I was able to continue with my trip. There was no floor mat interference with the accelerator pedal. The speed control system was not activated. I am a pilot with 500 hours of flight time and recent annual check ride qualification/training to handle emergency situations. Had my wife or the average driver been operating the car, there would likely have been a serious accident. The vehicle simply went berserk.
