I purchased a new ford taurus on 9-16-09. shortly after that, i noticed that all the running lights and interior lights would go on and off while the car was parked in the garage. i also noticed that the drivers door would unlock while i was driving it. i was told that a part was ordered on 10-27-09 and as of this date (12-10-09) the part has not arrived. the car has been "out of service " for 17 days. *tr
