Throttle body problem. All of a sudden I had no power and barely made it home. I had to be towed to ramey Ford in princeton, wv they replaced throttle body but I had to pay $100 deductible. This car was part of a customer service arrangement worked out with NHTSA but the VIN was not included and I was told it was not covered for cost of replacement. This was a very dangerous situation and could have resulted in an accident. I feel the part should have been replaced without any charge since other vehicles in this class had the same problem. There was no offer to reimburse me for my tow since the vehicle was totally disabled. This was a problem that Ford and the NHTSA were aware of and my vehicle had the same problem as others. I feel that I should not have to pay for labor or tow to correct a defect.

Vehicle loses all ability to control the throttle both while at highway speed and when pulling away from a stop. "wrench" fault indicator on the dashboard illuminates. Restarting the vehicle restores normal operating conditions until the issue reappears. There is no fault code on obdii reader after restarting the engine.

My car, on 4-5 occasions now, has lost all power while traveling on the freeway at about 80 miles per hour. I called Ford because of the electronic throttle body customer satisfaction program and my vehicle does not qualify because of the assembly plant that the car was built at. I can attest that my vehicle is doing the same exact thing that is described in the accounts of the problem with the throttle - without question. I urge you to expand the program that Ford is being required to do for this massive (over 1 million vehicle) problem. This appears to me to go beyond a plant issue to an engineering issue with the part itself.
