This is a serious safety hazard that could result in death or injury. If I hadn’t escaped in time, I would have been killed. I am urging the federal safety agency to investigate this defect and take immediate action to remove these vehicles from the road. Others may not be as lucky. This issue is life-threatening, especially because the fire started while the vehicle was in motion. These vehicles must be recalled and removed from use before more people are injured or killed.

Neither the air conditioner nor the cruise has worked since 46,000 miles. It needs a new air compressor which would cost over $1,000 and there are several other complaints for this issue plastered all over the internet.

I purchased a 05 mercury grand marquis and had issues with the headlights going out while driving at night. I seen that there was a recall on this issue for my vehicle but when I called the ford dealer they said my car wasn't registered for a recall. They said I would have to pay $135 for a diagnostic test and leave my car for 24 hours. No one was able to inform me why my specific vehicle was excluded from the recall. If I'm telling them that I'm having a problem that they clearly know about why are they charging me to fix it?
