Two problems related to automatic transmission park/neutral start switch have been reported for the 1999 Ford Explorer. The most recently reported issues are listed below.
Claimant states that the car was in park, engine off, and the emergency brake was engaged. Claimant left keys in the ignition and procedeed to the rear of vehicle. After cleanng the tailgate area, claimant went to remove keys. At this point the vehicle rolled backwards down the driveway with claimant half in the car. Vehicle hit husband's park car, and continued into the street where it struck a neighbor's mailbox, thus throwing the claimant from the vehicle. Vehicle continued folling down a very steep hill and went over a curb where we believed the vehicle flipped over. Claimant was taken to emergency room and was x-ray. Fortunately, there were no broken bones. Claimant easily could have been killed or seriously wounded by the vehicle.
Vehicle was placed in park, and when driver got out of vehicle, it started to roll. Vehicle crashed into a commercial truck. Dealer was contacted and problem cannot be duplicated. Problem still exists. Provide further information.
