NHTSA Complaint #11566823 — 2015 FORD F-350

Front end suspension has on several occasions began to violently shake. It appears that the driver side front wheel begins to bounce rapidly after hitting large or small defects within the road surface. This occurs only when driving on highway type roads where posted speeds typically exceed 55. (Texas has some posted speeds of 80 mph and I drive this area often) Numerous times during this occurrence I have had little to no control of my truck's direction of travel. The only solution to date that has worked is to slow down to a near stop while still in the middle of high speed traffic. When this "death wobble" occurs, I have zero control of my vehicle as far as steering is concerned. We no longer allow our children to ride in the truck with us as this has become a dangerous driving environment. Additionally the violence of this wobble aggravates an pre-existing medical issue within my neck and head. (Veteran with (2) TBI's and severe nerve damage in my neck) The dealership has confirmed the issue and suggested I replace the front suspension and my tires. (My tires still had 20K+ miles left on them) The vehicle has been taken to a dealer for the vast majority of it's service and maintenance. I have mentioned the "death wobble" on several occasions' and even agreed to have the entire front end suspension along with all four tires be replaced. This seemed to have fixed the issue in the short term, but it has returned with considerably more violent shaking than before. I asked the dealer to repair again, but they refused without additional payments, as the repair is now more than 90 days old. No warnings are given prior to this violent shaking other than the initial jolt. Even with a warning, traveling at 60-75 mph along with confined traffic the chances of becoming involved in a possible life-threatening accident become extremely high.
