Failure Date: 10/22/2014

Headlights went out. I received a notice from Ford in April of 2014 there was an electical/lights problem and they would repair if owner actually had this problem. I had no problem until oct 2014. Went to my dealer quick lane/Ford in topeka, KS. They reported that part has been on back order since may of 2014. Contact another Ford dealer who reported same. Light have regularly gone off since that time. What is a reasonable time to expect that they would have correct parts to replace as neither dealer had any report as to when part might come. VIN: 2mefm75w25x660472 field service action number: 14n01 fsa title: extended warranty coverage on lighting control module.

4 Headlights Turn Off While Driving problem

Failure Date: 08/18/2014

Failed lamp control module, headlights fail to work, only high beams work when lever is held in flash position. Ford issued an extended warranty program 14no1 in the spring of 2104 for just this part for 15 years or 250,000 miles. No replacement parts are available in the USA. The dealer says they have a waiting list that goes back six months. Have talked to regional managers in dearborn, mich. All say they have no idea of a shipping date, much less a delivery date, from supplier. Won't indicate how many vehicles are effected, but has to be many due to extended warranty program. Their solution is if the lights don't come on or go out while driving is to hit under the dash to the right of the steering column and they should come on. This means there are cars on the road that people are driving during daylight hours knowing that their cars headlights are not working correctly, but no parts available from Ford to honor warranty. This means that cars are being used that may not be legal to drive in the rain (most states have headlight on if raining law) and also will not pass state inspection. I understand that parts are not always readily available, but should be available in several days. If this is a known problem, why are there no parts? no other help or loaner vehicle program is available.

I drive on the highway from to work. During the winter months, it is dark at 6 am. This morning, as I usually do, the light switch was on and it was on low beams. Suddenly, the headlights went out. I pulled over and stopped. The side markers and the parking lights were on. I sat for a few minutes to decide how to get home with no lights. Then the headlights came back on. I took a chance, they remained on, that day. It would occur periodically then daily, sometimes two (2) to three (3) times on the drive to work.

While driving the vehicle,suddenly the headlights went out. I parked for a while, then I turned it on and the lights came on. Now the lights go off sometimes, while driving ,and I have to hold the lever back towards me, to have the high beams on until I reach my destination. This is very unsafe. I dont realy drive as much at nite, and I come home early, before it is dark. Thank you.

The low beam headlights failed while driving at various speeds without warning. I was forced to drive with the high beams illuminated. This happens very frequently. The vehicle was not taken to the dealer for diagnostic testing. The manufacturer was not notified of the failure. I called the dealer. They said it was not covered under warranty. He said the part would be about $600, and with labor all cost would run about $800!the vehicle was not repaired the current mileage was 71,100. Remanufactured lcm is about $300 or new about $500 from an independent auto parts store.

Failure Date: 11/28/2013

The headlights turn off randomly. The running lights stay on but the normal headlights will go off randomly and then come back on several to tens of minutes later. I can hear a clicking sound when the lights do go off and back on. When the lights do go off, I can hold the high beams on if I hold the stick toward me. Sometimes initiating a turn signal will cause the headlights to come back on.

9 Headlights Turn Off While Driving problem

Failure Date: 10/19/2013

High and low beam headlights failed while driving at high speed on dark 2 lane highway in upstate NY. Fumbled with light controls until by random chance discovered that by holding "flash to pass" stalk back, high beams could be activated. Made it home steering with the right hand and holding flash to pass with left, blinding oncoming drivers with the high beams all the way. This is an intermittent problem in the lighting control module (lcm) that can sometimes be cured by kicking the lcm, which is located under the dashboard above the accelerator pedal. Hard to do at night, on a dark road, at high speed, in traffic, while holding the flash to pass stalk with the left hand and steering with the right hand. This intermittent light failure occurred again the week of may 25, 2014. This vehicle should not be driven at night and should be recalled immediately before someone gets killed.

Failure Date: 05/22/2013

I was returning home with my wife from a trip to charleston, SC, at about 10:00 pm, driving at 60 mph, when my headlights suddenly shut off. That happens in the vicinity of awendaw and there are no street lights in the area. Both my wife and I screamed in panick while I was trying to slow down the car and staying in my lane on the highway. I was thankful that the turn signals, marker lights and brake lights still worked, so any other cars would be able to see me. When I finally pulled up the side of the road without any mishaps, I inspected the car and found out that all the fuses were good. I then restarted the car and still did not get my headlights to come on. I played with the turn signal/ low beam/high beam lever and got the flashing high beam position to work, so I drove home to myrtle beach holding the flashing high beam lever up to light my way. Otherwise, I would have to hire a taxi, spend the night in the nearest hotel to wait for daylight to resume my trilp home. Apparently, the problem with the headlights shutting off without warning while driving at night comes from the lighting control module installed the the 2005 Mercury Grand Marquis that malfunctions when the cars reached an average mileage of 69,000 miles (some as early as 30,000 miles, up to 114,000 miles documented).
