One problem related to car accelerates on its own has been reported for the 1997 Ford Explorer Sport. The most recently reported issues are listed below.
On February 16, 2004 at approximately 2:30 pm I was pulling my wife's 1997 Ford Explorer Sport into a diagonal parking stall. I had almost come to a complete stop when the engine began to roar and the car began to accelerate against my braking. I pressed as hard as I could on the brake pedal but the car continued to move forward until it struck a car opposite my parking stall. I pushed the gear shift into neutral and turned off the engine. I checked my right foot position and confirmed that I was only pressing on the brake pedal. When I released the brake pedal the car rolled back a couple of feet. I shifted the car into park and restarted the engine and backed the car up another 3 feet. The sudden acceleration has not recurred but I am concerned that it might again.
