Alternator battery light came on, car died. Changed Alternator, no help. Changed Battery no help. Car would sometimes start and run, other times so dead the auto locks would not unlock the vehicle. This is a very dangerous situation as there is no warning when the car will lose all power. Suspect the power control module, but with no assurances from Ford it would fix it, the car was traded in as a junker. Sad for a leather interior, sunroof car with 60,000 miles. Not even Ford wanted the lemon.
