Most recent owner complaints, unedited.
Consumer states during highway driving vehicle completely shut down and would not restart. Thick film ignition moudle had to be replaced.
I was proceeding home in evening rush hour traffic when the car engine quit instantaneously. I was forced to stop in the right lane of traffic. Although in the right lane I could not pull off of the road because there was a barrier with no shoulder for me to pull onto. Fortunately I was not hit by another car although I was sitting where traffic had to stop abruptly and swerve to avoid hitting me. The car was sitting in traffic until a tow truck arrived approximately one hour later. The vehicle traffic where I was stalled routinely moves at over 50 miles per hour which luckily for me did not result in a major accident.
Vehicle was driven approximately one mile and parked. Upon exiting the vehicle, the operator noticed smoke coming from under the hood. After opening the hood, the operator identified the source of the smoke as the alternator. Operator continued to observe the vehicle and noted that the volume of smoke was increasing. After approximately two minutes, the alternator burst into flames. Arcing was seen and heard within the alternator. The alternator had been previously replaced by fette ford in wayne, nj in sept 1999 and, upon subsequent failure, again in approximately jan 2000. Fette ford stated that rebuilt ford alternators were used in both cases.
Wiring harness shorted out, causing all lights inside vehicle, as well as tail lights and park lights to stay on. In addition, fuse burned and melted. Repairs made at owner's expense.
