NHTSA Complaint #11467981 — 2016 FORD F-250

On approximately 26 May 2022 I was driving down an entrance ramp to I-77 and the front end of the truck started shaking very severely -- violently. This was without any warning and I had never experienced anything like this before on this vehicle, or any other vehicle I had ever driven. I took my foot off the gas and pretty much coasted to the side of the road to a stop. I caught my breath, suspected there was an issue with the shock absorber, and slowly accelerated again and merged onto the interstate and drove the rest of the way home. There were no more similar instances like this for several days. When I got back to my RV I check the shock and could see no problems. On 5 June I went to a local Firestone Service Center for an alignment check and to see if they could find a problem. They made minor corrections to the alignment; told me they could find not problems, even though they told me the tech said there was a lot of vibration at about 55 MPH when he took it for a test drive; and then advised me to take it to a Ford dealer for review. On my drive back to my RV I experienced about 4 more instances of very severe and violent front end shaking of the truck, typically when I was at 55 MPH or faster. In each case the shaking would not stop until I pulled over and came to a stop. On Monday, 6 June I visited two Ford dealerships and one independent repair shop to try and get an analysis and fix. I have been able to make an appointment for 8 June. During the drive back to my RV on the 6th I experienced 3 more vibration events. One of these was as I was decelerating and exiting the interstate and was traveling at about 45 MPH. This front end vibration shakes the front end of the truck and steering wheels extremely bad. I was able to maintain control but it would not take much to send the truck into a sideways skid. From what the Firestone tech told me I believe they were able to confirm the vibration issue, but they did not communicate the severity very well.
