Car Accelerates On Its Own problems of the 1998 Ford Expedition

I backed out of a parking space and had my foot on the brake as I shifted out of reverse and into neutral. As soon as I shifted into drive the engine accelerated with great force. I kept my foot on the brake pedal and shifted back into neutral and turned of the ignition stopping the vehicle and avoiding an accident. I measured the resulting tire skid mark from the left rear tire and it was about 9 feet long. I took the vehicle to the Ford dealer on January 23, 2006 for a diagnostic checkup. They kept it overnight and tried to duplicate the unintended acceleration and to check out any possible mechanical defects. None were found and the vehicle was returned with a suggestion to have a vehicle data recorder installed when one was available.

While pulling into a parking space engine suddenly accelerated for no known reason, almost caused vehicle to run into side of a building. Consumer slammed on brakes and shifted into park. Vehicle at dealer shop for inspection. Please feel free to provide any further details on this matter.

Upon re-positioning my vehicle in a driveway, I backed up then attempted to proceeded forward. At this point my SUV suddenly accelerated while my foot was on the brake. Despite standing on the brakes, I took-out the bumper and trunk lid of the vehicle parked in front of me. The accelerator pedal was never depressed.

While driving vehicle suddenly accelerates.

I have experienced an uncontrolled acceleration when braking to come to a stop with my 1998 Ford Expedition. This has happened 10 times since I purchased the vehicle in September, 1998. The first occurence was on 9/19/1998 and the latest occurrence was 3/01/1999. Intermittently, when pressing on the brake to come to a stop the engine accelerates as if I were pressing on the gas pedal rather than the brake. The degrees of the engine acceleration have varied from somewhat mild to extremely violent. The only way to stop the vehicle is to put the transmission into neutral since the acceleration still pulls the vehicle forward even with my foot on the brake (standing on the brake). This uncontrolled acceleration has always occurred when the vehicle is moving at a very slow speed in the braking process to come to a full stop. Luckily there have not been pedestrians or other automobiles in front of me when this has happened. I have had the vehicle back to the dealership several times concerning this problem. The dealership and Ford have not provided a fix for the problem as of this date. This is an extremely dangerous defect in the vehicle and is a potential killer. All 10 occurrences of the problem happened with less than 4,000 miles on the vehicle.
