NHTSA Complaint #11308784 — 2018 FORD F-350

WHILE DRIVING THE SPEED LIMIT ON THE FREEWAY AND HITTING A "ROUGH" PATCH, THE TRUCK'S WHEELS THEN BEGIN SHAKING, CAUSING THE WHOLE TRUCK TO VIOLENTLY SHAKE. THERE IS A SIGNIFICANT LOST OF CONTROL OF THE VEHICLE. THE SHAKING WON'T SUBSIDE TO REGAIN CONTROL UNTIL THE SPEED DROPS BELOW 50 MPH OR LOWER. THE VEHICLE HAS VERY LIMITED RESPONSE TO TURNING WHEN THE SHAKING IS HAPPENING. THIS SEEMS TO BE SIMILAR TO WHAT I'VE HEARD DESCRIBED AS A "DEATH WOBBLE". THIS HAPPENS WHILE DRIVING STRAIGHT AND MAINTAINING SPEED (I.E. NOT TURNING OR ACCELERATING OR DECELERATING). THIS HAS HAPPENED PERIODICALLY, BUT ALWAYS AFTER A CHANGE IN SURFACE (EXPANSION JOINT, POTHOLE, UNEVEN SURFACE). I HAVE DRIVEN OVER THE SAME SPOT WITH OTHER VEHICLES, INCLUDING A FORD EXCURSION, AND CANNOT REPLICATE IT. IT SEEMS TO BE SPECIFIC TO THIS GENERATION OF THE SUPER DUTY.
