when the vehicle approaches 45-50 mph on the highway, the car begins to shake violently, where it feels like the body/frame of the vehicle is going to separate from the car. the only way to resolve/reset this is to bring the vehicle to an almost complete stop and then re-accelerate. when this happens on the highway everyone violently shakes in the vehicle, and it is difficult to quickly bring the car to a halt as other cars are traveling at highway speeds behind the vehicle. this has been taken to the dealership multiple times over the years with no resolution.
