Too funny! Have had two Taurus'-both 94's. Brake problems with both-shimmy-no one can find anything wrong. My husband and my BIL both wrecked my wagon-I know better-don't tailgate anyone and don't hit the brakes hard. There is a gremlin in the windshield wiper control-sometimes they work and sometimes they don't. If you use the emergency flashers, the steering column makes a buzzing noise. Temp gauge bobs erratically if you don't keep the resevoir overfull. Current Taurus has close to 200,000. Going to drive it until it croaks.
Had this exact same problem wih a 94 GL wagon. A wierd, strong vibration appears between 65-70 mph, and has since the get-go. Despite many visits to the dealer, it was never fixed. The head gasket went out 1 month Before they issued the recall/repair notice. Other than that, it's been ok, though it's been driven lightly. It barely has 100,000 miles.
We gave it to our teenage daughter,and it is the perfect teenage car; being too embarrassing to cruise in, and the vibration keeps her from going very fast, or far.
