NHTSA Complaint #11452897 — 2018 FORD F-250

When driving above 50mph we experience a problem that our Ford service department originally called the Death Wobble, it is now called High Speed Oscillation. The steering wheel and entire front end of the truck shakes violently and I have to slow to almost a complete stop in order to regain control of the vehicle. We have have the steering damper replaced twice (the tech today said about every 20,000 miles) and the truck is in the dealer for the third time addressing this issue. This third time the work that is also being done involves a large nut that requires 450#'s of torque to adjust. We had to replace tires that wore out prematurely. This last time the impact of the violent shaking caused the other vehicles on the road to move away from us because they could see something was wrong as well. I don't scare easily, but these events are terrifying. The problem has been confirmed by a Ford Service department multiple times. This has not had third party inspections, but I will ask for the worn out part when I pick up my vehicle from the current servicing. There were not any warning lights or messages that gave alerts to the incidents. The incidents would occur on macadam, concrete, going downhill and uphill, on transitions between road surfaces and on roads that have rough surfaces from heavy use.
