The car de-powers and will not go above 20-25 mph. The anti lock brake lights come on. They will stay on for awhile and go off and on by themselves. This happens in traffic and is very dangerous. My daughter nearly got plowed over trying to get off the road. She called my scared to death. This happens intermittently. No wet or slick pavement, on a dry sunny day.

2003 Ford Thunderbird had spark plugs replaced four times. Vehicle slowed down to 5 mph without warning and would not pick up speed, and numerous engine problems. Water leaked inside the vehicle, the dealer found cracks and a tear around the weather strip and seal. The A/C control head assembly was replaced. The radio had to be sent out for repairs. The alarm would sound on its own. The light located on the rear view mirror would not go out. The ignition coils were replaced.

A couple of months after the car was purchased the battery light comes on and when it does no other electrical parts will operate. For instance if you have a window down you can't roll it up or the heater won't work. This has been an ongoing problem since the car was purchased. We've had the car to the dealer 3 times and they have replaced the alternator as well as overlaying electrical wires and none of this has fixed the problem. On one occasion they had the car for a month, put approximately 200 miles on it and still couldn't find and fix the problem. Our concern is that when the battery light comes on and nothing else electrical works what if you needed, say, the defroster to come on and it wouldn't it could pose a serious safety problem! the date in the incident box is just an approximation this has been ongoing since we've owned the car. Thank you.
