NHTSA Complaint #8012099 — 2001 FORD F-150

FROM ACCELERATION OF 25-50 MPH, A SEVERE VIBRATION WOULD OCCUR IN FRONT OF VEHICLE. AT 70 MPH OR MORE REAR END WOULD VIBRATE SEVERELY ALONG WITH A ROARING AND GRINDING SOUND. VEHICLE BEEN TO THE DEALER FOUR TIMES, DEALER WAS UNABLE TO LOCATE CAUSE OF PROBLEM. *AK THE VIBRATION IS EXTREME TO THE POINT THAT CONSUMER IS AFRAID TO RIDE IN THE VEHICLE. THE POPPING SOUND IN THE DRIVERS SEAT FEELS LIKE THE SEAT IS TRYING TO MOVE FORWARD OUT OF THE LOCKED POSITION. WHEN CONSUMER PURCHASED THE VEHICLE THE VEHICLE HAD A NOISE UNDERNEATH. IT WAS TOLD TO CONSUMER THAT IT WAS BEING REPAIRED WITH A NEW MUFFLER THAT HAD BEEN ORDERED. AT THE TIME THE MUFFLER WAS BEING REPAIRED THE VIBRATION ALSO WAS WORKED ON. THE WORK DID NOT CORRECT THE VIBRATION PROBLEM. A SERVICE MAN TEST DROVE THE VEHICLE WITH THE CONSUMER AND AGAIN THE VIBRATION PRESENTED ITSELF. FOUR NEW TIRES WERE INSTALLED BUT THIS DIDN'T SOLVE THE PROBLEM. *JG
