I just purchased a 2010 ford fusion sport about a month ago. I just noticed that my exterior lights (headlights and tail lights) will flash every 10 minutes once I lock my doors, like 10 minute 6/8 seconds everytime. There's no remote start or after market alarm system installed on the car. Any ideas???? Called the dealership I bought it from and then a local ford dealership and neither had a clue why it was happening. One did say try locking it from the door switch and not the key fob, which I did but still the lights flash every 10 minutes. Driving me insane!!!!!!!
