The lighting control module has failed and my brake lights and dash board lights turn off after couple minutes while driving with the lights on. I took my vehicle in to dealer already once for problem to be fixed a year ago. They did repair but now same problem is occurring again. I went back to dealer sunrise Ford in fontana and they said recall work is only warranty for 1 year or 12k miles. The work was done in December 2023. They want to charge me $230. 00 for diagnostic. But issue is same problem as before. Recall number is 15s39. Driving without brake lights is dangerous and has limited my driving. I cannot go out at night. I do not have another vehicle. This affects my life. I've called other dealers and they refuse to do the work.

I received a recall on my car in 2019 to change the lighting control module as my headlights could go out without warning. Although I had not experienced this, I brought my vehicle to the local Ford dealer who changed the part. Over the pandemic and now since my wife and I are in declining health we have driven very little after dark. However, I recently had to go to the pharmacy at walmart and returned home after dark but my headlights went out completely. Now I am having this problem and the local Ford dealer said there was no second recall so he wants to charge me between $500 and $600 to correct the problem. I think this is Ford's responsibility to correct. Please assist in making the manufacturer aware of this.

For sometime now the headlights on my 2002 Mercury Grand Marquis appear to fade or dim soon after turning them on; giving the impression they are losing power and about to fail. I live in the mountains and am very familiar with each and every turn I see on the roads I travel. You see that is the matter of fact- if my headlights failed; I would not see the turn possibly a fatal fact.
