This is an ongoing problem -- this winter the headlights started turning off on their own, forcing you to hold the brights in position so as to continue driving at night. At first they came back on. Now they come back on rarely. The first time the lights are put on after the car has been parked for a while they may stay on (better than 50/50 chance). But after turning car off during night and restarting, the lights always fail a few minutes or less into your drive. Why hasn't Ford been forced to recall this?

While driving at night, my headlights without warning, extinguished. I turned the 'high beams' on and they also failed to light. I stopped and after a few minutes, the lights came back on. I searched the internet and found that many Ford Crown Victoria / Mercury Grand Marquis (multiple model year) automobiles are suffering from the same problem. It is apparently a failure in the 'lighting control module' (lcm). There are many web sites that offer re-manufactured lcm's but I question why this is not a safety recall? I think that losing your headlights while driving at night would somehow qualify as a safety hazard and this should be the manufacturer's responsibility to fix this problem.

We had just left a funeral home and driving back home on a 4 lane road. We turned to avoid getting on the highway immediately and decided to take another route. As we were heading up this 2 lane road that was dark all of a sudden our headlights and instrument panel lights went out and cars coming at us were flashing their lights. I slowed down and was able to pull over to a side street. Sat there trying to determine why the lights were out. Turned the switch from the on position to the automatic position and the lights came back on. We drove all the way home on back roads to avoid getting on the interstate, not knowing if the lights would go out or not. Read the manual to see if we had missed anything and then got on the internet and saw the hundreds of people having the same thing happen to them. I will contact the dealer and see about fixing it but from what I have read, the light control module is bad and so are the replacements. I am hopeful that there is a newer improved model that is now being used. Thank god we were not on the highway or we could have been killed. This is a serious problem.

While driving down the interstate my headlights cut off. My parking lights remained on. The only way to see the road was to hold the high beam switch. This is the fourth time that this has happened in the last 2 weeks. There is no pattern of occurrence. I investigated on the internet and there are multiple reports of this happening throughout the country. The headlight module seems to be the problem.

This is a very dangerous problem. The lights go out on the Mercury marquis. It is intermittent. Sometimes, they will go back on. I have to hold the high beam to get home. Extremely dangerous! they should have a recall and stop trying to slide over the issue.

As I was driving the headlights went completely off, switched to manual, worked for a few minutes, then went off again. Tried turning car off and back on, no lights, had to hold dimmer switch forward to get lights. This has happened numerous times since the first one. Now not even holding the dimmer switch forward always works. Today we were stopped because tail lights were out (driver was holding dimmer switch forward). Tail lights also flicker at times when headlight goes out and control panel flickers too. We have gone to local independent repair service and are having difficulty getting control module due to large back order. So what are we to do in the meantime? this is extremely dangerous to those in the car and others on the road. I understand recalls are when there is a dangerous situation, and this definitely qualifies! so we now own a car that we can't drive whenever headlights are needed, which is very limiting. So far I have not been able to get hold of Ford directly to complain about this. We are not the original owners, but that should not matter on such a serious issue! this complaint is about a 2005 Grand Marquis.

Headlights go out intermittently.

- West Seneca, NY, USA

While driving on a dark county road all headlights went off. Had to drive nearly a mile with no head lights or street lights before I reached a place I could pull over. After car sat for several minutes lights worked again. Extremely frightening and dangerous! I can not believe this is a known issue and no recall has been issued!

- Ogdensburg, NJ, USA

This is the second time the lcm has, without warning, failed. The first time, while driving along US1 after dark, all lights - headlights, tail lights, and dashboard light - went off!! there were no street lights and cars could not see us from behind and we could not see where we were going! we were terrified. Our lives were at stake as we anxiously and extremely slowly made our way home. The repair was outrageously costly. And, of course, we were restricted to driving only in sunny daylight hours as lights are required when raining. Now, this has happened again. The car has been taken to the local Ford dealer. However, although the part has been ordered for over 10 days, there is no word as to when it will be available and we are about to take a four-day trip! we have contacted the Ford Motor Co. About this problem, both by phone and by email, and all they can say is that it needs to be fixed. Excuse me! this is a life and death issue!!! we could have been killed on the highway due to a faulty lcm! in all our years we have never had this happen with any other car. We have read in several blogs that there are defective modules being used - yes, from Ford Motor Co.! does there need to be a highway death due to this defect before Ford will acknowledge this problem and replace this part at their expense?? updated IVOQ 12/19/12

Driving at night when head lights went out all other lights were on. We could keep the high beams on by holding dimmer switch up. Lights would come on and them go off again.
