The official notice
Defect
On certain vehicles, the light emitting diode (LED) driver module in the headlight assemblies could fail. If this happens, the high and low beam headlights, parking lights, daytime running lights and turn signal lights may not work. Note: This problem would cause an "Advanced Front Lighting Feature Temporarily Unavailable" warning message to be displayed and the turn signal telltale to flash at the same speed as when a turn signal bulb fails.
Safety Risk
Headlights and/or exterior lights that don't work properly could reduce visibility and/or make the vehicle less visible to others. Turn signals that don't work properly may cause a person not to recognize when a driver intends to turn or change lanes. These issues could increase the risk of a crash.
Remedy
Ford will notify owners by mail and send a wireless over-the-air software update to eligible vehicles to update the LED driver module software. Alternatively, you may schedule an appointment to have the update performed at a Ford dealership.
