All headlights and parking lights shut off without warning while driving at night in the darkest part of the road. It happens when the lights are set on automatic, and when they are set on manual. There was only a ditch on either side of the road (no shoulder) and no street lights....scary!!!!!

In early June the headlights started going out with no warning. They would also flash on and off when the wipers were on. Took the car to a mechanic and he said the lcm was bad. $500 to repair. Was looking online for a lcm and seen that Ford was extending their warranty on the lcm under the number 14N01. Looked at my Ford recall letters and seen that Ford sent out this warranty 14N01 to me in April of 2014. Took car to the dealer on 11 August and they confirmed the lcm was bad and would replace it. It is now 15 September and the parts are still not available. Now the wipers and wiper washer come on even when the wiper switch is off. Lights come on when their not supposed to. Anti-skid was also flashing on and off. Car may be unsafe to drive but I need transportation for work and cannot always use my wife's car. Ford will not offer a car for me to use. Should this be a safety recall" do I have any options with Ford"

Lighting control module intermittently not working. Not reliable for evening travel. Part on back order from Ford dealer with no estimated delivery date - I was told anytime from 1 week up to one month. Will need to rent a vehicle. What compensation for car rental do you offer due to the fact there is no estimated delivery date for this part?

Grand Marquis 8-cyl

  • 80,000 miles
While driving down the highway @ 65 mph the headlights suddenly went out causing a very dangerous situation. I tried the switch in every position to no avail the only solution was to use the flash to pass bar. I safely pulled off the road and tried restarting the car and moving the switch to different positions, nothing would work. The only way to use the lights is the flash to pass (bright lights) switch which causes not only a safety hazard to my family and other drivers but is against the law to drive with only bright lights. Ford has issued (customer satisfaction program 14N01) which is a step in the right direction but the dealerships all say that the lcm is on backorder and will be at least 45 days to receive this safety hazard part. Mt family is now stuck in a vehicle that can only be safely driven during daylight hours. Please help, parts stores have these parts and Ford should have to be required to purchase them if they can not provide the parts until 45 days later. Is this safety issue going to take someone dying *trbefore it is rectified?

June 10 while driving 65 miles per hour my lights failed. I was fortunate there was no accident. Took car to Ford dealership and was advised it was the light module. Dealership advised that Ford acknowledged this was a faulty part and the warranty on said part had been extended for 15 years. The local dealership ordered the part 45 days ago but has not been received. I personally called Ford's customer service several times but Ford still cannot give me an estimated date the part will be received. This same dealership has worked on my car several times but no one mentioned the defective module. This could easily lead toe death and destruction. Your help in resolving this matter would be appreciated. My case #with Ford is [xxx] I ran google search and this is a very serious problem and many people are not aware of it.

  • 50,000 miles
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.

Lost headlights. Lighting control module failed. It was dark and I was out of state, approximately 325 miles from home. I stayed in va and returned home in NY state the next day during daylight hours. I traveled through a mandatory "headlight one zone" on route 15 in Maryland. I traveled through construction zones in pa on I81, where headlights are required to be on. Approximately two weeks earlier I received a letter from Ford(customer satisfaction program 14N01) notifying me that this failed part was now part of an extended warranty. Problem is that the part is not available and Ford Motor Co. Cannot tell me when it will be available. This should have been a safety recall. Imagine an unsuspecting driver, driving at night on a two lane country road when this part fails. If this driver is going around a corner, the car would almost certainly leave the road and crash.

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.

At about 8 pm, I was driving on an interstate in heavy traffic when the headlights went out. I was able to pull off the interstate. I turned the headlight switch on and off, but the headlights did not come back on. After a few minutes, the headlights just came back on. I turned on my blinker to get back on the interstate and the headlights went off again. My husband and I swapped seats and he took over the driving. The lights came back on and he pulled onto the interstate. The lights went off again and as long as he pulled the blinker towards him, then we had bright lights. Whenever he released the blinker, the lights went out. After driving for about 10 minutes with the bright lights on, the dim headlights came back on and stayed on for the next hour as we drove home. He was told at a Ford dealership that it was the light switch, so he replaced the switch. The next night the headlights went off again. I pulled off the road for a few minutes and the lights came back on and stayed on until we got home about 20 minutes later. We have not driven the car at night since then. We have since learned via this site that there is a problem with the light control module. The service man in the Ford parts department said it was his experience that when this happened it was the light switch. So we spent $137 on a part that we did not need.

The lights were on in normal mode when I heard a click and they suddenly cut out. I was driving slowly in town and was able to pull over; I discovered that I could hold the turn signal control signal for the passing brights and get light; otherwise no lighting would turn on regardless of attempts to change the lighting mode and restarting the car. Eventually the lights came back days later, but have continued to cut out intermittently ever since. This is a major safety hazard as there is no predicting the failure, and the brights are not good to have to hold to use.
