I was driving home on a dark country road with my granddaughter in the back who is 3 1/2. had the high beams on. Lost headlights, dash lights, tail and brake lights. If it wasn't for knowing the road and no other vehicle was around would have caused a bad wreck. There are a lot of lakes and hills around where I drive. Hit the breaks an came to a stop flipped the headlight switch a couple of times and changed to dim lights and everything came back on. This has happened before and it is only when the high beams are on. If this would of happened on a highway or with other vehicles around hate to think of what would happen. Ford says there is no recall on this problem. It has happened a few times but with the part being over $600 and then paying someone to put it in. I can't afford to do anything.

Vehicle was being driven on a Maryland secondary road and the entire lighting system failed. The car continued to operate but with no headlights, running lights or interior lights. Basically it forced us to find a quick safe pull off using a flashlight for vision. Tomorrow the car is receiving a complete diagnostic check to determine the fault. It seems the lighting controls seem to be a problem as the battery and alternator checked out fine. This is a major life safety finding and needs to be addressed by Ford now with the number of these vehicles on the road.

Vehicle was going about 35 mph when all of a sudden it started shaking. Then, lost its traction control, and caused the lights in the dashboard to turn off. This eventually led the engine to shut off, and the driver lost steering. Taken to dealer for a checkup, but the results showed that the cause was undetermined. Car shuddered, followed by engine shut down resulting in loss of power brakes and steering.
