NHTSA Complaint #11472154 — 2012 FORD F-350

While traveling on the highway at 70~75 mph the vehicle went over a small highway joint. This caused the truck to shake violently with little to no control. Only after dropping speeds less than 45mph did the violent shaking stop. The sudden slow down in the middle of the highway, the violent shaking and the lack of steering control was extremely dangerous and caused an immediate life safety issue to myself , my family and other vehicles and motorists near mine. The vehicle was inspected by a mechanic. The tires have been balanced and rotated are not worn. The shocks on all four tires were replaced. The steering stabilizer shock was replaced and joints inspected. The problem persists and only is replicable during highway speeds. The event comes without any warning and the vehicle is uncontrollable.
