Two problems related to vehicle shudder have been reported for the 2019 Ford F-250. The most recently reported issues are listed below.
Vehicle mileage was ~23,500. While towing a gooseneck trailer that I had previously towed several times, on I-74 on wet pavement, speed 70 mph the steering wheel and vehicle began to shake violently after driving over a bump in the road. The vibration frequency was probably something like 4 hz. I gradually slowed the vehicle with sustained vibrations occurring until speed was approximately 35 mph. I stopped the vehicle and inspected all truck and trailer tires and the steering linkage but I could not find anything abnormal. I contacted the local dealership and was told the truck was still safe to drive. This phenomenon reoccurred several times over the next 15 miles. This was easily the most violent shaking and frightening experience due to a vehicle malfunction I have ever encountered. In winter driving conditions, I suspect I would have lost control of the vehicle. I completed the trip at speeds under 60 mph and the vibrations did not return. Once I unhooked from the trailer, the vibrations returned driving down a township road at 55 mph. Each time this occurs, it is started by driving over a bump in the road. The frequency and amplitude of the vibrations are constant while decreasing vehicle speed until the vibrations stop, typically around 30-40 mph. To date I have received no notifications of recalls related to this phenomenon. The dealership I purchased this truck from stated that they had "heard of this problem in some 2017 models, but never in a 2019 model. " this truck is primarily highway driven. It is completely unacceptable that any suspension components should wear enough to cause a potential safety issue in less than 25,000 miles. Ford should be held responsible for fixing this issue.
Vehicle shakes uncontrollably from the front end at 70mph. Usually occurs after hitting a bump or uneven lanes on the highway. Steering wheel shakes so hard that anything on the dash or center console falls to the floor board, chances of items landing behind brake pedal or gas pedal.
