“On 12-7-2016 I was told by fremont ford in fremont ca that they would not be able to fix my headlight problem -- a factory recall item -- until march 2017 at the earliest because the part would not be available from ford until then. The headlights won't stay on. I can't drive at night or in the rain (headlights required in the rain in ca). Unacceptable.”

NHTSA complaint #10933742, filed 2016-12, 42,000 miles

“While driving at night, the headlights will suddenly go out. Tail lights and other lights continue to work. I do not know what makes them come back on some time later. I can make the high lights come on by holding the high light, (turn signal) lever toward me this too is dangerous because I am blinding oncoming drivers. This is certainly a serious safty issue.”

NHTSA complaint #10574837, filed 2014-03, 130,000 miles

“I went to have my lights fixed due to a traffic violation for high beams.I took it to be repaired at mall of georgia ford. My low beams would not turn on. They replaced the wrong part when there was a warranty out for the lighting module. They refused to fix issue and my low beams continued not to work. In order to make the lights work you have to hold down the high beam lever .”

NHTSA complaint #10671625, filed 2015-01, 82,913 miles

“We were driving and all of the sudden the head lights went out randomly. We tried to turn the switch the other way and back and forth but that did not work. The only time the light work is if you hold the high beam switch towards your body making it very dangerous to drive. Sometimes they come on when you first turn the car on and then turn off again within minutes.”

NHTSA complaint #10588735, filed 2014-05, 155,000 miles

“My Grand Marquis lights would not come on last night and went to auto zone. They checked all my fuses. Still nothing then I was stuck trying to hold the highbeams on the whole drive home. Started to look into this problem only to see I am not the only one. Trying to find out what I should do next.”
