NHTSA Complaint #11010189 — 2010 FORD FUSION

IN LOWER GEARS / BELOW 3500 RPM, I WILL OCCASIONALLY EXPERIENCE A SUDDEN DECELERATION, AND THEN AN ABRUPT ACCELERATION AS THE VEHICLE ATTEMPTS TO MAKE IT TO THE COMMANDED SPEED. THIS ONLY OCCURS WHEN THE VEHICLE IS ALREADY IN MOTION, MOST OFTEN CITY STREETS, OCCASIONALLY WHILE ACCELERATING ONTO A HIGHWAY. I BELIEVE THIS CREATES A POTENTIALLY DANGEROUS SITUATION, AS A DRIVER MAY NOT HAVE THE FULL, CONSISTENT ACCELERATION THAT HE EXPECTS TO HAVE. THIS ISSUE BEGAN SHORTLY AFTER RECEIVING "CHECK FUEL FILTER" CODES, DUE TO A POORLY DESIGNED INNER GAS CAP GASKET, WHICH ALLOWS FOR CONTAMINATION TO OBSTRUCT THE EASY FILL SYSTEM'S INNER SEAL. I BELIEVE THIS MAY ALSO BE RELATED TO AN ISSUE WITH A THROTTLE BODY CONTROLLER, SIMILAR TO THE MANY FORD PRODUCTS AND CUSTOMERS WHOM HAVE SUBMITTED PRIOR COMPLAINTS. NOT SURE WHY THOSE THROTTLE BODY CONTROLLERS DIDN'T GET A RECALL, THE PROBLEM IS COMMON ENOUGH AND THE POTENTIAL DAMAGE SUBSTANTIAL.
