Bought the car used with approx. 45,000 miles on it from Ford dealership. Within a week I was back at the Ford dealership I bought it at. The car would not accelerate, stuck in gear, jerk violently. They gave me a loaner car to drive, another 06 Ford Fusion. They told me there was nothing wrong with the car and it was the way I drive. I told them I didn't have any problems with the loaner car or any other car I've ever driven or owned. They insisted I was wrong. Over the next month I brought the car back to the dealership and encountered the same resistance. The problem got progressively worse and dangerous to drive to the point where I would be going 60+ mph on a highway and the car went into neutral. The transmission completely failed in 2010, at that time I had it replaced, costing $3,000. May 31, 2012 - approx 65,000 miles. Similar problems again. Car would not accelerate, very hesitant, entire car shakes violently while driving. Check engine like came on. I took the car to my mechanic, he tested and determined three coils went bad. Looked in the car and discovered the coils had actually melted. With research, determined the computer system had failed. Coils and computer system need to be replaced. Approx cost (so far) - $1500. 00.
