NHTSA Complaint #11408660 — 2014 FORD F-250

AT SPEEDS OVER 50 MPH SEVERE SHAKING OCCURS AND THE TRUCK BECOMES UNCONTROLLABLE UNTIL SPEED IS REDUCED TO BELOW 45 MPH. THE TRUCK'S STEERING DOES NOT RESPOND AND CANNOT CONTROL THE TRUCK. AT THIS POINT I CAN ONLY DRIVE THE TRUCK AT SPEEDS AT OR BELOW 45 MPH. THE ISSUE OCCURRED ON A HIGHWAY DURING THE DAY. AMBIENT TEMPERATURE WAS 52 DEGREES AND THERE WAS NO RAIN. THE ROAD AREA I WAS TRAVELING THROUGH WAS KNOWN FOR UNEVEN ROAD SURFACE AND COULD CAUSE SOME SHAKING IN THIS TRUCK AND IN OTHER VEHICLES I'VE DRIVEN BUT NEVER TO THIS EXTREME. THE SEVERE SHAKING STARTED WHILE THE TRUCK WAS AT 65 MPH (70 MPH ZONE) AND BRAKING ALSO BECAME DIFFICULT. I HAD TO KEEP OFF THE GAS AND LET THE TRUCK SLOW ITSELF TO A STABLE SPEED THEN I EXITED THE HIGHWAY. THE TRUCK IS A 2014 FORD F-250 WITH APPROXIMATELY 109400 MILES ON IT. THE AUTO SHOP I WILL TAKE IT TO TOMORROW SAID THAT THIS IS A COMMON PROBLEM WITH THESE TRUCKS AND THAT I SHOULD REPORT IT.
