I own a 1999 mercury cougar. I have maintained the vehicle per the service manual through the local mercury dealership. Sometime during early april 2005, I noticed that the car hesitated and jerked violently after about fifteen minutes of normal driving. We were able to drive the car in for service. The dealer "diagnosed" the problem and replaced a part. The car continued to malfunction the very next day. I returned to the dealership and was told that the problem was with transmission. I have had the transmission replaced by a local ford dealership. I am not sure whether the old transmission is available.

After regular tire rotation at 28,000 miles, the car started to pull to the right (the side where the defective tires were on), the steering was jerky and an audible thrumming could be heard. It was noticeable as slow as 10 MPH and grew increasingly worse as the vehicle sped up. When we had the vehicle inspected at three different locations, they all concluded that tire separation was the cause and was the possible cause of the car being out of alignment. We corrected the alignment and purchased four new tires (yokohama) and the problems are gone.( dot number: w2b0 tire size: 215/50r16 )

I was driving down an interstate road on the morning of july 3rd 2000. A considerable amount of rain had fallen on the road and it was still raining slightly the section of the road that I was on was completely straight. I was in the left lane doing about 55mph on the 65mph road when I felt the car lurch and begin to turn toward the left. I looked down at my instrument panel and noticed that my tachometer was on zero and my warning lights were all on. The car started to spin counterclockwise very quickly and crossed over three lanes of traffic where it finally crashed into a guardrail on the right side of the road. I was facing oncoming traffic when the car finally settled.
