Owner report 10547840 · 2013-10-14 (October 14, 2013)
THERE IS A MANUFACTURING FAULT WITH THE POSITION OF THE BRAKE AND THE GAS PEDAL. IT IS VERY EASY TO MOVE THE RIGHT FOOT FROM THE GAS TO THE BRAKE AND LEAVE ENOUGH OF THE FOOT ON THE GAS AT THE SAME TIME. IT ALLOWS THE BRAKE TO BE PRESSED BUT ALSO APPLIES GAS TO GIVE A VEHICLE A SURGE WHILE BRAKING. HAD THE SAME SITUATION WITH A 2001 FORD TAURUS AND FORD ISSUED A RECALL NOTICE TO HAVE THE PLACEMENT OF PEDALS CHANGED. *TR

Recall history
1 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
10V161000 · Seats:Front Assembly:Recliner
Reported: 2010-04-20 (April 20, 2010)
FORD IS RECALLING CERTAIN MODEL YEAR 2010 FUSION, EXPLORER, EXPLORER SPORT TRAC, AND MERCURY MILAN AND MOUNTAINEER VEHICLES MANUFACTURED BETWEEN DECEMBER 15, 2009 THROUGH FEBRUARY 3, 2010 EQUIPPED WITH FRONT SEAT MANUAL RECLINERS. THESE VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 202, "HEAD RESTRAINT." THE RECLINER GEAR PLATE TEETH MAY BE OUT OF DIMENSION SPECIFICATION WHICH COULD RESULT IN LIMITED PAWL TO GEAR PLATE TOOTH ENGAGEMENT.
Consequence: IN THE EVENT OF A CRASH, THE SEATBACK AND HEAD RESTRAINT MAY MOVE REARWARD, INCREASING THE RISK OF INJURY.
Remedy: DEALERS WILL REPLACE THE MANUAL RECLINERS FOR BOTH POWER AND MANUAL SEATS FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE APRIL 30, 2010. OWNERS MAY CONTACT FORD AT 1-866-436-7332.
