NHTSA Complaint #11296812 — 2015 FORD F-350

I OWN A 2015 F350 SUPERDUTY. I HAVE NOTICED HIGHWAY DRIVING AT 50 MPH OR HIGHER WHEN CROSSING OVER A TRANSITION IN THE ROAD THE FRONT END SUSPENSION/STEERING CAN GO INTO A VIOLENT SHIMMING THAT CAN ONLY BE OVERCOME BY A RAPID DEACCELERATION TO LESS ~30MPH. THERE HAVE BEEN TIMES THAT THE SHIMMING IS SO VIOLENT ITS HAD TO CONTROL THE VEHICLE. YESTERDAY, CROSSING OVER A BRIDE ON RT 222 SOUTH IN LANCASTER CO PENNA, THE TRUCK CROSSED A TRANSITION A THE END OF A BRIDGE. IT WAS ALL I COULD DO TO REGAIN CONTROL OF THE VEHICLE WHILE OTHER CARS HAD TO SWERVE TO MISS HITTING ME AS MY TRUCK WAS IN THIS RESONANCE UNTIL I COULD GET IT UNDER CONTROL. THIS ONLY OCCURS SO FAR ABOVE 50MPH, BUT, IT IS MUCH MORE COMMON AT 65-70MPH. I AM TAKING THE TRUCK BACK TO THE DEALER AGAIN FOR ANOTHER EVALUATION. THIS SITUATION DEVELOPED AT ~ 76,000 MILES. THE TRUCK HAS 92,000 MILES NOW. UPON FURTHER INVESTIGATION INTO THE EVENT ONLINE I WAS ABLE TO DETERMINE THAT THIS HAS BEEN IDENTIFIED AS THE "FORD SUPERDUTY DEATH WOBBLE." I ASKED THE DEALER ABOUT THIS TERM AND THEY SAID THAT THEY HAVE HAD THIS SITUATION ON QUITE A FEW FORD F250-F350 VEHICLES. I NO LONGER FEEL VERY SAFE DRIVING A $72,000 VEHICLE THAT IS KNOWN TO HAVE A DEATH WOBBLE, WHICH AS AN ENGINEER, WOULD APPEAR TO BE A DIRECT RESULT OF AN INADEQUATE DESIGN BY THE OEM. I BELIEVE WE NEED THE GOVERNMENTS HELP RESOLVING THIS SITUATION SINCE FORD DENIES THE EXISTENCE OF THIS COMMON SITUATION.
