Headlights randomly turn off. Doesn't seem to matter if I'm driving or not.

Driving home at night in my 2004 Mercury Grand Marquis all of a sudden my headlights went out. The only way to have headlights was to manually hold back the high beam mechanism on the steering column. Eventually they will come back on for a while but cut off again. Through research I found out it is a lcm module and can be fixed for approximately $700. I think Mercury should bear some or all of the responsibility for this as it will eventually cause a very severe accident.

Headlights went out while driving the vehicle. This was on a dark, dark, 2 lane country road with little or no shoulder. Using the high beam "hold" function light would come on high beam. Working switches would not bring lights back on. Checking lights later, found lights would go out within 5 mins - stay out for less than 5 mins and then repeat. Repair was the lcm module which dealer charged aprox. $700 to fix. Very dangerous and scary! tail lights did stay on.

2004 Mercury Grand Marquis. Headlights began going off by themselves while I was driving and will not come on at most of the time. Every indication I have is it is a faulty lighting module control. This is very dangerous and it is only a matter of time before someone or me is killed because the lights will suddenly go off on a dark winding load. Please consider a forced recall on this problem immediately.

Same symptoms in auto or manual headlight mode. If I stop the car it will come back on. It then might go off after a while. I see others have had this same problem, this was confirmed by my local Ford dealership. Very common problem with serious safety concerns.

We have 9 Mercury Grand Marquis in our fleet. We are a 24 hour transportation service and our cars are out a night. The lights just turn off without warning and our drivers now have to drive in the dark until the lights come back on after shutting the car down. Or, they may not come back on and have to have the car towed in. We have purchased this company in May 2008 and purchased all nine cars at the same time. We have replaced four of the nine so far at the cost of $591. Each, our cost according to whiteys' automall mansfield Ohio. If this item is so defective that we have to keep replacing this same item in each car, why was this item not recalled and corrected. I am listing one date, there has been 4 different dates, 4 different cars. (2) 2004's (1) 2003 and now (1) 2002, our 2005's and 2006's have not indicated a problem as yet.
