NHTSA Complaint #11538442 — 2019 FORD F-250

While driving on the interstate in South Dakota I may have driven over a small bump in the road. I was in the passing lane. The truck immediately started shaking and I felt like I was going to lose control of the truck. Weather conditions were perfect, sunny and the road was completely dry. I immediately started braking thinking perhaps I had blown out a tire but the truck continued to shake violently while I tried to move back into the driving lane and on to the shoulder of the road. The truck did not quit shaking until I had stopped the vehicle on the shoulder. There was a lot of traffic on the interstate as the Sturgis motorcycle rally had just ended and I had a cyclist behind me as I pulled back into the drivers lane however he had enough space and time to allow me over. I checked my tires and all were fine so I slowly tried pulling back onto the interstate and the truck performed as it should. I drove at a much slower speed making sure it did not happen again. I did some research online and found what is called "the death wobble on Ford trucks" and feel this is exactly what I encountered. I feel this is a very unsafe condition that should be reported and felt necessary to issue this report.
