What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Diane, my wife and passenger testified that when the engine surged, she put both feet on the brake pedal to stop the car. After no avail, she applied the emergency brake. This caused the vehicle to spin into a heavily traveled intersection. As the vehicle spun, my wife tried to put the vehicle into ?park?.
While my wife was driving my cougar she made a 5-10 mph left hand turn the driver side tie rod snapped and my wife lost all steering. She side swiped one car and hit head on with another vehicle . I had only had the car for about 9 months when this happened .
While backing out of a parking space the vehicle suddenly and uncontrollably accelerated into a brick wall. The vehicle has been totalled. Consumer was injured in accident. Tp sensor replaced due to stalling.
Vehicle experienced unexpected and unintended acceleration from apark position. Independent engineer identified the problem as a cruise control cable holding the throttle opened, ea90-009.
Vehicle stalls when starting from a complete stop or a rolling stop, recall 96v071 was completed on vehicle, but the problem still exists possibly due to an engine failure.
While driving about any speed vehicle will shut down, but all electrical parts will still be working, like headlights/ radio/ power window, and air conditioner. But not cold and motor will still be working; ignition module had been replaced four times, and now has to be replaced again.
Seat belt failure reported both to galpin lincoln-mercury and ford motor corp. Because of no documented recall, they refused to repair it. I have been driving ever since without shoulder belt protection.
The upper layer of the firestone tire on the front left was completely separated from the rest of the tire. This was at a speed of about 60 mph. The tire was in good condition with no damage.
