What is your vehicle sales or service issue?:I received a letter from the ford company about getting my headlights replaced. My headlights does not work at all and I have to hold my high beams in order to have some lights at night in order to see. This is very uncomfortable when driving with one hand especially, when I have my babies in the car with me. When I went to the ford dealership in march. They told me that the parts were on back order until june or july. I went back to the dealership (lilliston ford in kingsland, ga)in the beginning of december 2014. They told me that the parts are still on back order and that they're are 3800 people waiting on those parts. I've been pulled over numerous of times because of my hands slipping off of the high beams and I've had 2 accidents because of my headlights. I need to be put in a rental car are something until my lights are fixed. This is dangerous and is not a safe way to be driving at night. .

Car jerking so that I took to reliable mechanic. He drove car and said the transmission is slipping. The mechanic said the transmission fluid smelled a little burned consistent with slipping of the transmission. The mechanic's recommendation was to wait until transmission completely failed since he thought the only option was to have transmission replaced. This 1995 mercury grand marquis has only 34,000 miles on it. I had heard recently that many of the mercury's and ford's had early transmission failure.
