  • 65,000 miles


On December 23, 2015 I was driving my 2004 Mercury Grand Marquis through an intersection in harris county, Texas. I had just received a green light and was proceeding to make a left turn when my vehicle was hit by another vehicle in the driver's side front. The damage to my vehicle was severe. The at fault driver's insurance company declared my vehicle a total loss. My vehicle's air bags did not deploy. I was wearing my seat and shoulder belts at the time of the collision. I was examined at a nearby emergency room. They said "no serious injury" but my orthopedic surgeon said I have a separation of my left shoulder.

Malfunctioning headlights on vehicle. Unexpectedly without warning the headlights failed making for a dangerous, scary drive home. Manually had to hold down the highbeam lever towards me to drive the hour and half home on the highway.

The instrument panel, radio, A/C, etc., all interior lights flicker randomly. I notice this when I am driving at night mostly. It does it during the day, but is not as noticeable. I have already changed the module one time, and it is doing it again. Has been occurring for two years.

When I was driving my Mercury Grand Marquis on the high way the lights just shut off at first it would happen for short periods of time and if I pushed it in they would work well after a month of two it completely wouldn't stay on anymore and the high beams I would have to use won't work any longer as well.

Headlights flicker on and off without warning. I have to hold my bright lights switch towards me in order to see on the road at night on my way to and from any given destination without warning. I've had it fixed but didn't fix the problem because it continues to happen.

I received a customer satisfaction program letter on April 14 2014, regarding my lighting control module. The module went out on June 30 2015. I had the letter but I forgot about it until I was looking up some papers just recently. Of course I had it fixed by a private garage on 6/ 30/ 2015. It only had 61,416 miles. On it at that time. I can not see why I can not be reimbursed for the repair now. It cost me $387.02. I have been a Ford customer since 1956.

Vehicle headlights work intermittently. Cruse control does not reset or turn on when supposed to. This is also an intermittent problem, sometimes resetting, and sometimes not. Headlights would sometimes not turn on when driving unless pulling turn signal arm toward steering wheel and holding. High beams only would work.

I was driving in a small town on small street with no street lighting. I was about 15 miles per hour and started to brake for a stop sign. Headlights flashed and went out. I turned my headlights off and then turned them back on and they were good. After making a left turn from the stop sign about 100 feet my lights went out. It took a while to find in the dark a place to pull over. I tried turning my engine off completely, and when I started it back up, no lights. I played around with my light levers and finally found that if I depressed and held the flash lever my lights would work. I had one heck of a time trying to make to left turns and hold down lever to get home.

I just recently purchased this vehicle from a small dealer on 6/30/15. On 7/8/15, at about 8pm, I was driving home from a long trip for work, got about 20 miles into my 70 mile drive, when it seemed like the road in front of me was darker than it should have been, I made sure my headlight switch was on headlight mode. It was actually on automatic mode, so switched it to reg headlight mode. I was not use to this new car yet, having not driven it much at night yet and just thought it was my imagination, that they were not on as they seemed to have worked previously. I kept driving as I could still see the road in front on me but it was definitely getting darker and darker and now cars coming from the other direction were flashing me, so I had a feeling that they were not working. When it was safe to do, after trying unsuccessfully to get the headlights working by turning the switch dial, I immediately found a somewhat safe spot to pull over. I got out, looked in the front and surely they were not working but only in flash mode. I turned car off, checked fuses, waited about 10 more minutes, then started car again. They finally came on, so I took advantage of the situation and made a dash towards home again, which was probably another 35 miles or so. I do have aaa, if I needed to use it but just wanted to get home. I made it home safely, thank god but this seems to be intermittent, as they work sometime and other times they don't. I was wondering if there is any recall on this matter as it seems to be a huge safety issue and I do not want to be in anymore positions where this keeps happening. I work late a lot but since this has happened, I'm extremely nervous driving car past a certain time now and can't afford this to keep happening as this is my main car, I use daily. Thank you very much and look forward to any/all replies back. Have a great day. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I started my car after dark and did not have any headlights. All the other lights worked. The only way I could make the headlights function was by holding the high beam switch on the signal lever toward me all the way home, over 1 hour.. when I got home I looked on the internet to see if this was a common problem and it is with this year and model car. It is a safety issue and the manufacturer should warn and address this problem.
