NHTSA Complaint #11503891 — 2018 FORD F-350

I have a 2018 F350 with about 60k miles, otherwise excellent condition. Problem started about 2 months ago (around Nov 2022) or about 1 month after the last shop maintenance visit. Description: Coming home from work with driving speed around 50-60 mph the front end started shaking strongly. Had to slow down quite a bit to get it under control or stop shaking. The incident has been repeated on other roads. The stimulus that starts it all is when some roughness of the road is encountered. This shaking has become violent at times and have had to take evasive maneuvering to avoid an accident or damage to the truck. No warning lamps have come on nor have any other indicators. The problem has progressed to where it may be unsafe to take it on the freeway for any trips. I do fear for my safety and have to be vigilant at all times. The dealer will be notified on 27 Jan 2023 so a record can be made. Have gone on-line to find out that over a thousand other similar reports are out there and video footage. I have seen this happen on other Ford chassis specifically the 2004 Thor motorhome built on a Ford F53 chassis.
