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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

I am currently having problems with my 2004 Mercury Grand Marquis with the head lights not coming on or going out. All other light stay on. Turning the light switch on / off and it won't come on. 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. Dealer tells me it is a failure of the light control module (lcm).

  • 80,000 miles
The contact owns a 2004 Mercury Grand Marquis. The contact stated that the headlights suddenly stopped working. In addition, the turn signals and bright headlights would only illuminate whenever the switch was held. As soon as the switch was released, the lights would dim again. In order to drive at night, the contact would have to hold the switch at all times. The failure has occurred on three occasions. Usually, the headlights work normally when the vehicle is parked overnight. The contact scheduled an appointment with the dealer, but they have not yet inspected the vehicle. He believes that this is a manufacturer defect. The failure mileage was 80,000 and current mileage was 83,000.

2004 Mercury marquis. After 2-3 hours of driving with the headlights on, they will go out. All other lights continue to work properly. This is a very dangerous situation. I stopped the car and continued with my trip during the daylight. I believe this is a problem with the lighting control module and is a common problem.

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.
