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.

My headlights failed. Ross tire and service performed diagnostic service. Informed me of need for lighting control module replacement that could be done for free at a Ford dealership because of a recall. Ford never sent me a recall notice! I was minutes away from being on the I-10 atchafalya basin bridge which has no shoulder or lighting! the dealership in lafayette fixed my car free of charge however Ford has failed to cover the cost of the diagnostics done for me at ross's tire and service. I was on a city street when my lights failed on my way to I-10. I have documentation.

I was traveling on northfield road in bedford heights Ohio and turned right on to the drive way that leads to walmart. The steering wheel snapped completely loose spinning around. I lost control of the steering and the car crashed into a curb before I could apply the brakes. This occurred approximately an hour after I picked up my car from Liberty Ford dealership for repairs done in response to recall number 13S08 - steering column shaft and customer satisfaction program number - 14N01. (lighting control module).

Headlamps go out intermittently while driving at night. Ford dealer says only way can fix problem, which is an investigation, customer satisfaction # 14N01, is for the problem to be occurring when it is checked. This is absurd, as the problem is known to be intermittent - related to bad relays / relay installation. These idiots need to be told to fix the problem before someone kills someone just to demonstrate that the problem exists!

My husband and I were on vacation on August 14th 2015 when we were going to leave our location, we turned car on and headlights; when we noticed headlights would not turn on at all. We manually turned the knob multiple times and no lights turned on. When he pulled turn signal lever back toward him, we came to a conclusion the only way we could travel was with the manual high beams on. He had to hold the lever the entire way to our next location in the mountains which was dangerous for us as well as other drivers. The headlights somehow came back on. And on August 26 2015 I just had the same problem with headlights not working unless holding back the manual high beams lever. This time they did not come back on. Not only am I as a driver blinding people with high beams, I am risking my driving by holding down a lever while trying to drive. The lever hits the steering wheel and makes it difficult to turn the wheel. This is a serious problem that many others with this year make and model are experiencing. This needs to be addressed and fixed

The headlamps decided to quit working right when I am driving down the highway at 45 miles an hour. Could not see anything. Other drivers going the opposite direction were honking and flashing their lights at me. This is very dangerous, and somebody could get hurt.

Both low beam headlights went out at the same time and won't come back on. The high beam "flash to pass" works but I don't want to "blind" any on-coming traffic, so I will not drive at night until this problem is repaired !

As I was driving at night, my vehicle's low and high beams (lights) suddenly cut off. Unexpectedly, the road I was traveling became very dark because I live in rural areas in West Virginia. Unfortunately, a second later, my car ran over a small boulder on the side on the road causing a damage (small cracks) at the bottom right hand side of my bumper. Nevertheless, I put the emergency lights on until I returned home right away. Earlier this week, I used the car again without any lights issues. However a day later, the issue returned again. This time I was traveling in the highway at 60 miles per hour. All low/high beam lights cut off. My only solution was to hold the "flash to pass" lever towards me, and the high beam lights would turn on. However, it is extremely cumbersome driving this way. I've been told by many mechanics that the main culprit is the lighting control module (lcm) and this safety issue has become extremely common in Grand Marquis especially 2005 models. Consumers and perhaps the government may need to further intervene, so Ford can do something about this safety/hazardous. In my case, my bottom bumper suffered, but it could have been worse - it could easily cause an accident at any given time. Currently, I only use my vehicle during the daylight hours. I've been told that repairs can exceed $700 or more and in some instances, the issue returns within a few months after replacing this part. This electrical issue should perhaps be further investigated as the lcm could be the main culprit, but something else could also be triggering the lcm to fail. Thank you greatly!
