Driving on Florida highway #70 headlights went out and only high beams worked while holding them on (pulling handle toward me). I am 75 and a female, I was very upset having to drive 24 miles home in this way!

Driving down interstate, headlamps went off unexpectedly without any adjusting of auto lamp feature. Only able to get high beams to come on when holding the stalk to the on position. Very dangerous. Next startup lights working fine....until they don't when you are on the highway and at highway speed...certainly a hazard especially for night-shift worker. Cant believe Ford doesn't think this is a safety issue.

Driving down the road and the headlights went out. All other lights work fine, but the headlights work intermittently. I have to use the bright lights and hold the switch while driving in order to be able to drive at night and that is just crazy. I'm blinding everyone I pass and it's very hard to drive that way.

At 69000 miles the lighting control module, climate control module, restraint control module stopped functioning. All at the same time. Odd they all go out at the same time. Safety issue.

While driving down the hwy my headlights went off then back on, then off. This is a known problem with what Ford Motor Company calls the lcm (lighting control module) which they have determined was due to in part to poor sodering at manufacturing. There are thousands of the complaints filed, with the same issue. I cannot drive me car at night in fear of loosing lighting as they come on and off sporadically. Why has no recall been issued. I was informed by dealer they are all aware of this issue as well. The part costs $499 plus labor. (who can afford this, better yet Ford needs to own up) this eventually is going to lead to vehicle loss of control with consumers, and fatalities I am afraid, just as the Ford Explorer did... please have the nhtsb investigate this further, and make Ford mo. Company due a mandatory recall. This is a very serious issue I'm afraid, and the consumer is having to pay the price for Ford negligence. Any insight into this investigation is greatly appreciated.

Lately when I crank the car at night the lights do not come on in the automatic setting. I switch it to manual and they still do not come on. When I switch it back to automatic they usually come on. Sometimes I have to do this twice to get them to come on. Several times I've had them go off when driving and got them to turn back on this way. Quite a few times I've left a brightly lit parking lot at night not realizing the lights hadn't come on and suddenly realized it when I pulled out into the road.

While driving my 2003 Grand Marquis the lights go out and come back on intermittently. This is a major concern that Ford Motor Company knows about this and has not offered a recall yet. Guess their waiting for deaths to occur before doing so....so sad. There are so many of these same complaints about this until it is scary. Ford Motor Company-----own up and recall this.

The headlights turned off while I was driving at night. I had been driving for approximately 15 minutes. I was on a freeway with some over head lighting so I continued driving. After about 45 seconds the lights came back on. This has happened several times since the original incident. Has there been a recall for this issue from Ford/Mercury? this is an issue that has happened to quite a few Mercury vehicles as the web is packed with incidents of this nature by owners and have only back yard, shade tree mechanics advice to try this or that. One other item to mention is that when they turn off, I have always been driving at a time of night when few other cars are on the road (no on-coming headlights). Could the on-coming traffic sensor on the interior rear-view mirror for auto high beam dimming be somehow involved? this is a very serious issue that could be life threatening. I would appreciate a quick response.

Driving down the road and the head lights just go off, do not have any control over the selector switch, they only way to have lights is to hold the flash bright light on the turning signal and hold there, you might get lucky and let go of the turning signal and the lights might come on and go right back off, very unsafe, could cause a bad accident, I have priced this to be replaced and they are telling on about $650 for the part along, plus the labor involved, if they know this is happening and had complaints, they should replace the defective item, before someone gets in a serious crash or killed.

Headlights would not come on in the manual or automatic light switch mode. The only way to have headlights on is to hold high beam lever in the "flash more"( lever pulled toward driver). I found after a while if I kick my foot above the accelerator, the lights would come on and stay on for an undetermined time. Further diagnosis indicates a poor connection by moving one of the modules connectors.

Luckily I am driving home from work around 1230am on an interstate with moderate traffic. The headlights just go off without any warning. After some very close calls and not just a few upset drivers, I did manage to get off the road and onto the side. I discovered that I could hold the signal handle back I had high beam lights that let me get home. I have maintenance records on this car since it's first oil change at 3000 miles, the auto is well taken care of. I do not understand why Ford would not take the responsibility for this as from what I have already read, it is a very common problem, I guess not enough people have died from it yet.

The headlights on low beam would not come on - could only drive at night while holding the high beam light on. Being told it is the lcm and has to be replaced at a high repair cost. After much research about this problem, Ford should be paying for these repairs and not the consumer!
