NHTSA Complaint #10559219 — 2012 FORD F-250

I WAS SAFELY OPERATING MY FORD F 250 ON A CONCRETE BRIDGE IN PINE ISLAND FLORIDA . I WAS TRAVELING @ 63 MPH AND WAS MAKING A SLIGHT LEFT BEND . THE TRUCK CROSSED AN EXPANSION JOINT AND WENT INTO UNCONTROLLABLE VIOLENT OSCILLATION OF SUSPENSION AND STEERING . THE OSCILLATION WAS SUCH THAT THE STEERING WHEEL WAS DIFFICULT TO HOLD ON TO AND MY FIRST THOUGHT WAS MULTIPLE FLAT TIRES OR A WHEEL CAME OFF THE VEHICLE . HARD BRAKING TO UNDER 30 MPH WAS WHAT WAS REQUIRED TO STABILIZE STEERING TO "NORMAL" . THAT WAS THE FIRST TIME THIS OCCURRED AND I DISCUSSED WITH MY SERVICE ADVISER AT THE FORD DEALERSHIP THAT I PURCHASED THE TRUCK FROM. I INSPECTED VEHICLE AND COULD SEE NO DAMAGE OF OBVIOUS PROBLEMS . I MONITOR TIRE PRESSURE REGULARLY , HAVE NO MODIFICATIONS TO SUSPENSION OR STEERING ON VEHICLE . THE NEXT TIME THIS OCCURRED 12/26/13, I WAS TRAVELING APPROX. 65 MPH AND AGAIN WAS IN A SLIGHT LEFT HAND TURN AND CROSSED AN EXPANSION JOINT NEAR BIRMINGHAM ALABAMA ON HIGHWAY 65. I WAS SURROUNDED BY DENSE 65 MPH TRAFFIC AND THE TRUCK WAS UNCONTROLLABLE. THIS TIME THERE WAS A NEAR ACCIDENT AS I HAS A SEMI TRACTOR TRAILER BOTH CLOSE BEHIND ME AND TO THE RIGHT SIDE OF ME . ONCE AGAIN I HAD TO BRAKE RAPIDLY TO AVOID CROSSING LANES PUTTING MY FAMILY AT RISK OF SERIOUS ACCIDENT . THIS IS A HAZARDOUS CONDITION AND THE DEALER HAS NO EXPLANATION. THE FORCE IS VIOLENT ENOUGH THAT IT COULD EASILY DAMAGE PARTS OF THE TRUCK . AS A SIDE NOTE , THE FUEL PUMP CAME APART AND SLUNG METAL FRAGMENTS THROUGHOUT THE FUEL SYSTEM IN TRUCK WITHIN ONE HOUR OF THE VIOLENT OSCILLATION. *TR
