NHTSA Complaint #11495220 — 2014 FORD F-350

I have experienced an extremely violent vibration/wobbling of the vehicle at freeway speeds on several occasions. During these times, it is very difficult to control breaking, steering the vehicle, making it nearly impossible. I felt very unsafe not only for myself, but also other vehicles around me as I was driving a heavy-duty vehicle on the freeway at a high speed with essentially no control. Although I was shaken up, I was able to regain control of the vehicle and continue on my way. There have been no reports or inspections at this time. Prior to this happening, there were no warnings or messages. This happens twice in 2 days while driving on a long trip. Both times this occurred while driving at 65-70 mph and driving over a small bump in road.
