“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. …”
NHTSA complaint #11042676, filed 2017-11, 49,984 miles“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.”
NHTSA complaint #10379674, filed 2011-01, 17,445 miles“I had checked the tire pressures prior to a road trip and found them at 38 PSI. I reset the pressures to the spec of 33 PSI. Shortly the tire monitor came on and signaled a low tire pressure. I rechecked and they were ok. During my trip the light would keep coming on and I tried to reset the system to no avail. On my return, the power door locks kept malfunctioning. The door key pad would work sometime for both the doors and trunk. The next time they might not. The door switches on both passengers and drivers side would work sometimes. …”
