NHTSA Complaint #10550503 — 2011 FORD F-250 SD

AS I WAS DRIVING ON A ROAD AT A SPEED THAT WAS GREATER THAN 50 MPH I HIT A BUMP IN THE ROAD. THE FRONT END OF THE TRUCK AND THE STEERING WHEEL BEGAN TO SHAKE SO VIOLENTLY THAT I THOUGHT THEY WERE GOING TO FALL OFF. THIS HAD HAPPENED BEGINNING AROUND LATE NOVEMBER EARLY DECEMBER OF 2012. IT DID IT SEVERAL MORE TIMES AND I CONTACTED THE DEALER ABOUT THIS PROBLEM. THE TRUCK WAS SERVICED AND NOTHING IN THE FRONT END WAS FOUND TO BE DAMAGED AND IT WAS RECOMMENDED THAT I REPLACE THE TIRES ON THE TRUCK. THE TIRES WERE REPLACED AND THE TRUCK HAS BEEN FINE FOR THE PAST YEAR. ON 10/30/13 I AGAIN WAS DRIVING THE TRUCK AT A SPEED GREATER THAN 50 MPH AND HIT A BUMP IN THE ROAD AND THE FRONT END AGAIN BEGAN TO SHAKE VIOLENTLY. I HAVE BEEN PIN THIS SHAKING DOWN TO THE FOLLOWING CONDITIONS. IT WILL SHAKE IF YOU ARE DRIVING AT HIGHWAY SPEEDS, YOU HIT A BUMP IN THE ROAD (THIS BUMP DOES NOT HAVE TO BE BIG IT COULD BE AS SIMPLE AS DRIVING FROM THE ROADWAY ONTO A BRIDGE DECK) THE FRONT END WILL BEGIN TO SHAKE AND VERY QUICKLY GET VIOLENT. THE ONLY WAY TO STOP IT FROM SHAKING IS TO SLOW THE VEHICLE DOWN TO A SPEED THAT IS LESS THAN HIGHWAY SPEED WHICH WILL CAUSE THE VIBRATION TO STOP AND YOU CAN THEN RETURN TO HIGHWAY SPEEDS. THIS HAS HAPPENED SEVERAL TIMES AND I DO NOT HAVE THE EXACT DATES THAT IT OCCURRED PRIOR TO CHANGING THE TIRES. HOWEVER IT IS BEGINNING AGAIN AND THE FIRST TIME WAS ON THE 30TH OF OCTOBER 2013. *TR
