2013 FORD F-350 Electronic Stability Control Esc Problems

WOBBLE VIOLENT SHAKING

TL* THE CONTACT OWNS A 2013 FORD F-350. UPON STARTING THE VEHICLE, THE SERVICE ADVANCE TRAC AND HILL DESCENT FAULT WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO MALL OF GEORGIA FORD (4525 NELSON BROGDON BLVD NE, BUFORD, GA 30518, (678) 515-9339) WHERE IT WAS DIAGNOSED THAT THE RESTRAINT CONTROL MODULE NEEDED REPLACEMENT. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND REFERRED THE CONTACT TO NHTSA. THE FAILURE MILEAGE WAS 95,650.

WHILE OUR TRUCK ON A NORMAL HIGHWAY WITH MINOR IRREGULARITIES AND SOME ROUGH SURFACES AT A SPEED OF 60 TO 70 MPH, THE TRUCK WILL START TO OSCILLATE TO THE POINT OF INDUCING A VIOLENTLY STEERING WHEEL SHIMMY AND AN UNCONTROLLABLE BOUNCE OF THE FRONT WHEELS. THIS HAS HAPPENED TWICE IN THE PAST 2-MONTHS WHEN I HAVE TAKEN THE TRUCK ON THE HIGHWAY. THE TRUCK IS PRIMARILY DRIVEN IN TOWN, I AM NOW SCARED TO GO ON THE ROAD WITH THE TRUCK AS THE CONDITION SEEMS TO BE GETTING WORSE. I HAVE TO BRAKE QUICKLY AND STEER THE TRUCK TO THE SIDE OF THE ROAD TO STOP THE OSCILLATION. THE SHAKING IS HAS ALMOST CAUSED AN ACCIDENT BOTH TIMES WITH THE VEHICLE BEING VERY DIFFICULT TO CONTROL. ONLY AFTER SLOWING TO APPROXIMATELY 30 MPH DOES THE OSCILLATION STOP. UPON RESEARCHING THIS PROBLEM, I AM PERPLEXED WHY FORD OR THE NTHSA...
