On October 21, 2016, while I was driving on I-30 in dallas county, a fire occurred in the daimay-supplied driver-side visor lamp assembly of my 2009 Ford Mercury Grand Marquis. The Ford fuse system failed, allowing the fire to burn, melting portions of the visor and roof material. The melted material fell on my left leg and the driver seat and floor of the vehicle, causing 2nd and 3rd degree burns to my leg. Chrysler notified NHTSA of a similar defect in the daimay assembly on July 1, 2014, which resulted in the first of two Chrysler recalls on July 10, 2014. Ford, however, chose to not recall its vehicles with the daimay visor assembly system, despite receiving notice of similar complaints, claims and incidents before the subject incident. Therefore, I respectfully request that this defect be promptly investigated and that the unsafe system be recalled so that other consumers are not injured.
Interior lighting cable burned out. Lost floor lights, door lights and map lights.
The left turn signals (front, rear & dash) blink faster than the right ones indicating a burnt out bulb even though the left bulbs work. We replaced the front & rear bulbs twice and they worked normal for a short period of time. Then they revert to blinking fast. I replaced the bulbs the first time and the dealership service center replaced the bulbs the second time. There must be something wrong in the electrical system. I've noticed this with other Grand Marquis also.
