NHTSA Complaint #11456628 — 2018 FORD F-250

I have experienced at least 6 incidents with my truck in which it starts violently shaking at highway speeds. In order to stop the shaking, I have had to either slow way down or pull over and stop completely to get the truck to stop shaking. In the most recent incident, there was a semi truck directly behind me and I was barely able to get to the side of the road to avoid being struck from behind and I nearly went into the ditch. After the first incident, I took my truck to the local Ford dealership and they told me there wasn't a problem when they drove it even though I provided them information about the "death wobble" from sources on the internet. The problem continued, so I took it back and they put "stabilizers" on it. I had no problem for almost a year until it happened twice yesterday. The first incident occurred on 12-25-18.
