Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

While driving at night, the headlights suddenly go out. This is very dangerous, regardless of either driving on the highway or in the city (especially with pedestrians). They tend to stay out for 10-15 min before they start working again. While they are out, the brake lights go out at the same time, making it even more scarier, cant see to drive, and the car behind me cant see me slowing down or stopping, which increases the chances for an accident. Needs to be recalled asap. It appears that it is the lighting control module is faulty and the part itself is quite costly starting at $300 - $500 for the part itself or $800 installed.

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 panic 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 trip home. Apparently, the problem with the headlights shutting off without warning while driving at night comes from the lighting control module installed 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).

Headlights go off, tail lights and running lights stay on. After slamming door or slamming hood lights would sometimes come back on again for a while, then go on and off at random with light switch turned to "on". checked all fuses and relays I could access and all were ok. Has acted this was for three weeks now. It's dangerous to drive at night.

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.

Grand Marquis 8-cyl

  • 55,400 miles
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.
