I was driving down driveway and hit the memory seat button my my naviagator and the seat started to move forward and kept going forward until it reached the very farthest it could go forward. The lights inside were going crazy and the outside mirrors kept going up and down and acting crazy. I took the vehicle in on 8/20 and they found 7 electrical faults with the vehicle. On August 25, 2003, found out I had been carrying triplets but lost two and am now pregnant with one. Do not know if that was related or not. On August 30th the back liftgate is supposed to have senors in it and almost shut and trapped me in it. Luckily I got out unharmed. Scared to think what might have happened if it were one of my other children. The vehicle is currently sitting in a bay at the service dept. Ford told them not to work on it and I have no idea what is going on with it.
