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.

This is a complaint on Ford Motor Co. We received a letter for a recall in April, for the lighting control module. Not long after, the headlights went out. Nothing could get them back on. We took the vehicle to the dealer. The stated they did not have the part. That was over two months ago. The dealer still does not have the part. So the car has been sitting there for that length of time. We could not take a chance of driving it without any lights. How can the dealer get the part from co? it is ridiculous to send out a recall letter and then not supply the part....updated 10/22/14

Grand Marquis 8-cyl

  • 125,000 miles
In October 2011, I was driving at night when my headlights went off. I pulled into a parking lot to investigate the problem. I got out and took a walk around the car and all the lights were working except the headlights. I turned the lights switch off for a few minutes and the lights came back on. The problem worsened and I found that I could hold the "momentary" high beam switch on and the headlights would work -- as long as I held the switch in the high beam position. The situation worsened, and now the headlights will not come on for any length of time. The problem has escalated from October 2011 until late May 2012. If I need to drive the car at night, I must hold the "momentary" high beam switch while I drive. Once in a while you can see the headlights come on because the lights get extremely bright. Then I can release the "momentary" high beam switch. The lights will only stay on for about 10 seconds and then go back off. My mechanic told me that many Mercury Grand Marquis and Ford Crown Victoria's around the model year of my car have this problem. He has traced the problem to something called the lighting control module. It seems to me that this is an engineering problem. Ford wants $600 just for the part. If you search the internet for similar problems, you will find an abundance of very similar situations as I have described to you. Not everyone is reporting this problem. Please help! updated 08/20/12
