Twice in 113,214 miles the throttle body has failed at speed. this is a sudden loss of power anywhere, anytime day or night--just out of power and scrambling for a safe place to stop. the first failure was with 36,366 miles in a snow storm. the second failure was in traffic on the freeway. no notification from ford that this is a known problem has been forthcoming. the replacement part ford installed the first time was also bad and has failed at 113,214 miles. this is a dangerous failure, going from 65 mph to 5 mph in moments. there's confusion, panic to get the emergency lights on, and a struggle to get out of the way.
