NHTSA Complaint #11531856 — 2016 FORD F-250

I have difficulty maintaining control of my 2016 Ford F-250 (purchased in 2019) after hitting any bumps going highway speeds, and is notably worse if this happens during any non-straight sections of highway. Commonly referred to as the "death wobble," it does truly feel like the front end of my truck no longer has traction with the road and I am unable to steer the truck safely until the "wobble" resolves, typically once I reduce my vehicle speed under 40mph. There have been instances when I have hit a bump on the highway while the highway is curving to the left or right and my truck will skitter into the next outside lane without my control and have luckily avoided crash/injury. When I am towing my camper (31' 5th wheel), the issue seems to be deflected back to the trailer so I hit a bump and the front end movement gets transferred to the back so I have my trailer whipping back and forth until I reduce my travel speed. I have brought this issue to the attention of more than one Ford dealership and have had my vehicle inspected. I have had the steering damper replaced twice without resolution. One dealership noted a tire arm with "some play" which I chose to have replaced without any significant change in this issue. This dealership did acknowledge there was some steering/control issues with the truck prior to the part being replaced. They also recommended I replace my tires to reduce this issue, which I did, and have not noticed a change either. I maintenance my vehicle as recommended and this issue has been ongoing since 2021. At no point has any warning lamps, messages, or other symptoms appeared for this issue. My traction control light doesn't even illuminate when I have lost control of my vehicle and moved into another lane involuntarily.
