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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

LCM (lighting control module) failed, Ford covered on extended warranty. Relay in unit fails causing lights to go off while driving. I could kick it with my right foot and lights would cycle on and off. Could cause someone to freak out and crash.

Nice car rides great. But when the lights started to go out while driving at night, my family doesn't want to drive in it at night time, a real problem. Starting to think this car's a piece of junk. This is a safety hazard and should be recalled at once or should be fixed free of charge before someone gets hurt or killed because of your negligence.

If there are that many reports of this same problem you should try to fix it to give your company a good name and service record. That's why people don't buy American, we don't stand by our products anymore!!!!!!!!!!!!!!!
