NHTSA Complaint #10522497 — 2010 FORD FUSION

WHILE DRIVING ON INTERSTATE HIGHWAY @ 70 MPH WITH CRUISE CONTROL ENGAGED, WITHOUT WARNING, THE CRUISE CONTROL DISENGAGED, THE ENGINE DECELERATED SUDDENLY, AND THE 'WRENCH' WARNING LIGHT ON THE INSTRUMENT PANEL ILLUMINATED. I COASTED TO THE SHOULDER OF THE ROAD. THE ENGINE WAS RUNNING AT VERY LOW RPM (500 - 600 RPM). THE CAR SHUDDERED WHILE THE A/T WAS IN DRIVE - THE SHUDDER STOPPED WHEN THE A/T WAS SHIFTED TO N OR PARK. THE ENGINE SPEED DID NOT RESPOND TO PRESSING THE ACCELERATOR. CUT OFF ENGINE AND SHUT OFF ALL ELECTRIC ACCESSORIES. CAR RESTARTED AND RAN THE REMAINDER OF THE DAY. INCIDENT REPEATED ITSELF THE FOLLOWING DAY AT EXACTLY THE SAME LOCATION (AND THUS UNDER NEARLY IDENTICAL DRIVING CONDITIONS - THROTTLE, TORQUE, SPEED, ENGINE RPM, ETC). I REPLACED ELECTRONIC THROTTLE BODY (ETB) BASED ON RECOMMENDATIONS FROM MECHANIC, FORD DEALER SERVICE DESK, AND NUMEROUS ANECDOTAL ACCOUNTS FOUND ON SEARCH OF INTERNET OF NEARLY IDENTICAL EPISODES WITH OTHER FUSION OWNERS. THE ETB I REMOVED FROM THE CAR HAD A UNIFORM LAYER OF DARK COMBUSTION DEPOSITS ON THE BUTTERFLY. *TR
