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.

Headlights suddenly go out while driving at night. Switching between settings does not bright them back on. The only way to have any headlights on at all is to pull and hold the bar that turns on the brights.

I recently(2 months) returned my 2003 Grand Marquis due to the headlights going out intermittently. My mechanic explained that there was a recall for the failures of the lcm. The dealership replaced the device in January. Last night while I was driving in the dark, the lights went out again. This will again need to be replaced. Are they using faulty parts for the recall? this is very dangerous and I am lucky to be alive to even type this today.

I left the house after dark to pick up my husband from work. When I got to his job I turned the car off because I was early. When he got to the car and I restarted it the headlights did not come on. They came back on after I used the turn signal about 2 minutes later. After that we notice that occasionally the lights would go off while driving at night but would come back on after a couple of minutes. Until one night when they stop working altogether. It stayed that way till we took it to a dealership where they informed us that they were aware of it happening to other cars but the piece that we needed was on back order and we would have to wait for one and a half months. While we were waiting the only way to have headlights while driving was to hold the high beams stick because it wouldn't even work if you pushed the high beams to the always on position.

Headlights go out unexpectedly and w/O warning. This has happened at all different speeds, in a parking lot 5-10mph, on roadway 30-45mph and on the highway65-70mph. Lights will come back on just as unexpectedly w/O apparent cause. Have shut down and restarted car with no effect, turned light switch on/off, no effect and then they will turn on after several minutes while parked. Sometimes the lights will turn on and off several times before staying light.

I have escaped quite a few accidents on my way home. With the new time change, I leave work right at dusk. The lights will not come on. I live way out in the country and have to drive 15 miles out. I have to switch to my high beam when a car is coming my way, and I blind it and other cars as well. I am soooo tired of this. I am going to cause a terrible accident !!!! I took my recall letter to the Ford car dealership here in town months and months ago. I keep calling for an update, and they say that the part has not come in. What can I do?

1st incident: Headlights went off about 2 minutes after starting car and beginning to drive. Would not turn on again while driving or when car was stopped and running. Turned off car and tried again. Headlights worked for about 30 seconds. Continuing this pattern after 2 weeks. Headlights do come on when high beam 'flash' lever is held in on position.. have not tested how long they will stay on.

Our headlights just stopped working. You cant turn them on and the only way you can turn the headlights on is to push the stick forward and hold it forward while you are driving down the road. Other than that, they wont come on. All other lights are operating fine.

Both headlights suddenly wouldn't turn on. Very dangerous. Night driving prohibited. Ford has agreed to repair due to voluntary recall. Glad this didn't happen when I was out at night. I live near dark dangerous highways and this could have led to fatal driving conditions had it happened on the road at night.this shouldn't be a "voluntary" recall where you have to call Ford to get the fix.

While my wife was driving home at night, her headlights went out on her 2004 Mercury Grand Marquis. She tried all combinations to get the lights back on and had to hold the high beam passing light up while driving the rest of the way home. I took the car to the local Ford dealer to get it repaired and they told me it could take a month or more to get the part to fix it. In our area, thunderstorms come up regularly during the day, so the car can't even be driven during the day. Ford Motor Company says that they can't provide a loaner or a rental so that we can drive safely until it is fixed. I don't understand why headlights going out is not a safety issue.

My light control module has been determined by the local dealer to be defective. I've been told it is on back order w/ no eta. I've since been told the NHTSA has inexplicably found this to "not be a safety issue". I'm wondering on what planet the NHTSA drives that having intermittently working headlights is not a safety issue? I am expecting a more definitive and timely response to having my car repaired.
