I was driving down the freeway when my Expedition made a noise, the inside dash lights flickered and the transmission started acting up. I pulled over at a hotel. I called a tow truck who came to pick it up a few days later. When he started it the wiring harness caught unfire. The entire wiring burned up on the lift side of the vehicle. The mechanic told us we were luck to have stopped. If we continued down the highway my family and I would have been in great danger. I believe the fire was the fault of bad wiring. I check the recall sites and my vehilce was not part of the faulty wiring recall.
Within 1,000 miles the back up sensor rang when ever you put the car into reserve - has been serviced three times still does it today. Within 5,000 the mirrors would tilt too far to the outside then pop as they tried to continue to move further outside. Within 18,000 1)advancetrac light came cause the right front brake to lock up when turning left and the left front brake to lock up when turning right. Engine was shutting down going traveling at 70 mph. Transmission would not change out to next gear until very high rpm. Pop and clicking noises from under the dash (front passanger and drive side). Engine would not start. - authorized Ford blue oval repair center has replaced 2 abs modules, the battery, made repairs to the wiring harness, replaced two other computer modules.
