  • 56,000 miles


The headlights turned off while on the freeway. Since then it's happening more frequently. Now it's multiple times each morning on the 35 minute trip to work. Temporary solution is to manually hold the momentary brights switch. Holding this switch while driving is annoying, and unsafe since that it on the same lever as the turn signals.

My brother was visiting for my son's wedding and used our mother's car for transportation. He found that the headlights would not come on, and eventually found that holding the high beam switch "on", the lights worked. At the dealership he was told there was likely a recall to fix this. Since he has gone back home, I have been researching this for my mother. I found a closed "safety" issue, number PE08066, which is exactly what he experienced. Although you have a very low number of complaints listed, consider this: Most of these cars are purchased by older people, many mechanically incapable in addition to being unsavvy with computers and the internet, and tend to drive it less, especially at night, so the issue would not be noticeable for quite some time. If they did experience this, they probably paid some serious money to Ford dealers to get it fixed, not realizing that this is a huge safety issue and this should be fixed for free under warranty before failure of the module - the tsb talks about failure of the module. Well, my brother took it in for inspection with this faulty module, and it passed, so then do they not consider it "failed"? mother is 91 years old and would probably panic if the lights went out while she was driving it. This is a major safety issue, and should be rated higher to get the warranty work done!!! I plan to follow up with the same dealer and see what they have to say about this. My suspicion is that until it fails she will have to pay for this fix, which is not cheap. This is ridiculous. Listing my information instead of hers as she needs our help to deal with this kind of annoyance.

Traveling southbound on I-95 in early morning all lights went out for a few seconds, leaving us in total darkness. Lights came back on and everything resumed as normal for remainder of our trip home. A couple of month later same thing happened during a short evening drive near home. No lights. Researched this frightening occurrence and found that our year make model has this problem due to bad lighting module solder job. Contacted for Ford, no help. Eventually got a letter from Ford stating they would extend warranty on this part, but would only replace module if it was failing at time dealer looked at it, after charging $49 dollars to test for codes. It has not failed at a dealer location. I avoid driving at night as much as possible.

Headlights shut off unexpectedly while driving in complete darkness. Finally figured out I had to pull the "safe to pass" in order to get the headlights to stay on. Drove to work while pulling the "safe to pass" stick on my steering wheel. Absolutely unsafe.

Driving around a bend on a dark county highway in southern NJ, no street lights. My headlights go out and wont come back on. Since my steering is stiff, I almost wrapped myself around a tree. Thank god, I have good brakes and driving on brand new tires on a dry road or I would be dead right now. My mechanic has always claimed that the stiff steering is a common problem & a manufacturing defect, but cost prohibitive for me to fix. When I took the car today, he said it was definitely the lighting control module ($600 part). He was unaware of the chronic problem that is happening as of late with the lcm's in 2003 marquis. I think you guys closed the case too early on the lcm's, the complaints boards all over the internet about this problem are increasing in frequency. Combined with extremely stiff steering, headlights going out randomly is a recipe for disaster.

I was driving at early dawn when I realized in some shadier areas the headlights weren't working. I pulled over and confirmed this. I thought that instances of intermittent headlight failure the week before was a misperception on my part. I had received a letter from Ford weeks earlier; Ford has indeed confirmed this problem is due to their lighting control module, so much so that Ford's letter claims that the company will cover replacement for an additional 5 years. My car's module has now failed completely. I am unsure in how many earlier instances, especially in semi-lighter environments where it was less perceptible to me, this intermittent headlight failure put both myself and other drivers, pedestrians, and bicyclists around me in real danger. The failure of my car's module has since been confirmed by my local dealer. In addition, I contacted Ford directly. However, affected drivers, as well as potential future owners, both of whom have and will pose a danger to others, have not and will not have a remedy any time soon, according to Ford, despite their letter. Ford dealer and regional managers suggest that the part is out of stock indefinitely. Future drivers will have no remedy to their cars' unsafe conditions. An allusion has been made to some unsanctioned, uncovered, and pricey, unreimbursable fix with no guarantee of success, hence to guarantee of safety either. Worse still, Ford has categorized this issue as one not entitled to rental assistance despite their "covered" failed part being responsible. States' inspection processes will fail any vehicle exhibiting this clearly unsafe issue. The commonwealth will deem my unsafe and unroadworthy this month, leaving me with no recourse. And with no relief expected from the manufacturer, any other car suffering this failure will meet with the same fate. What is the worth of being "covered" without a safe fix?

Cannot get lights to work, pulled over by police (twice)going down the road, and didnt know lights were out. They come and go. Police said to do something like take it to dealer. They told me I was to fail auto inspection for this on the spot. Dealer says they want to test for a week and then they say they cant get parts. If I got to court one mre time or car is impounded I am seking my attorney. This is a safety defect with dangerous and negligent consequences.

Customer satisfaction program by Ford, #14N01: They (Ford) tell me in a letter that my headlights may fail without any notice of a problem. They (Ford) know this is not only possible, but that it has happened numerous times already. There are blogs that speak to this issue. If it is the function of your department to protect consumers then please do so. This is potentially a deadly safety issue..... if there is even the slightest chance this could happen I don't understand why this department has not rectified it and made Ford recall these vehicles.

The headlights on my 2003 Mercury Grand Marquis have stopped working. This has been an intermittent problem. The most recent issue left my wife and mother in law stranded along the roadside. The first time I thought it was the switch in the steering column because after working the blinkers the lights started working. The next time my wife was driving on the interstate highway and the lights just went off at interstate speeds. It seems this is a common issue and has stranded others.

While driving to work at 3:15am my headlights went out without working causing me to pull onto the should er of the highway. Lights would not come back on regardless of what I did at that moment. The only way to get lights was to pull the level back on the steering column in order to drive with the high beams on. The lights would only stay on with the lever held back until I reached my work. This has know happened with daily frequency which now has deemed my car undrivable after dusk until I get this fixed. From the research I have conducted, this appears to be a very common issue on the Ford Crown Victoria as well as the Mercury Grand Marquis. I was very fortunate that I was in an area that allowed me to get my car off the highway without incident but this may not be the case for the next driver who experiences the failure of the light control module for these vehicles.

While driving, lights turn off by themselves. It can be 3 minutes from departure they turn off or longer. They just don't stay on. Try to turn on manually and will not turn on. If I drive long enough they come on by themselves. Dangerous when on street with no lighting and oncoming traffic at night or driving next to trailer rigs who do not know my vehicle is on their right or left. Have read on internet many others have this issue with Ford products and other years.
