Tl-the contact owns a 2003 Mercury Grand Marquis. The contact stated that while driving 35 mph, the vehicles low beam headlights failed without warning. The contact was able to use the high beam lights to be able to see. The vehicle was not taken to a dealer. The manufacturer was not made aware of the failure. The failure mileage was 150,000. Ed.
While driving at night the head lights suddenly went out. The only way the lights would work after that is if you hold the high beam lever back.
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?.
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.
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.
