On Friday, August 29, 2014 at 1200 hours, I parked my vehicle in a mcdonald's parking lot. I backed into a space (the driveway was slanted down to the middle of the parking lot), moved the gear shifter to park, got out of the vehicle. I walked in front of the vehicle, stopped to watch traffic for a clearing to cross the parking lot, and the vehicle bumped me from behind. It was slowly moving towards the center of the parking lot. I jumped back in the vehicle and applied the brake to stop its forward motion. I checked the gear shifter which indicated that it was in park. But, I was able to move the gear shifter out of park, place it in reverse and back the vehicle in the parking space, and again placed the gear shifter in park. Again the vehicle started drifting forward. I tried several more times to place the gear shifter in park. Finally, it seemed to hold. I went in to eat my lunch and returned to my vehicle. The gear shifter would not come out of park. After several tries, it finally did. I drove the vehicle straight home. I placed the gear shifter in park numerous times before it would hold and the vehicle stopped moving. Each time the gear shifter indicated that it was in park. I applied the emergency brake and contacted the Ford dealership, alan jay Ford, 3201 us hwy 27 sebring, fl 33870, 888-448-1737, and spoke to [xxx] in the service department. Since it was the labor day weekend, the first available appointment is next Tuesday, September 2, 2014 at 0800 hours. I hope to be able to get the gear shifter out of park and into drive Tuesday morning for this appointment. This is a safety hazard. The gear shifter shows itself in the park position but is intermittently not holding. The vehicle moves on its own as it did in the mcdonald's parking lot, bumping up against my back. Fortunately, it was slow moving this time. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
