@Evil XR6T, Hi Evil XR6T, Sounds similar to a problem I was having with my BA XR6T. And like you, I want to put my experience out there in case anyone else is having similar problems. The problem started 2 years ago with a light vibration through the steering wheel at highway speed. I blamed the road but it didn't always do it in the same spots. I then blamed cruise control because it always happened when cruise was on. I would brake, get my speed down to under 80 then accelerate again and all was good. Ford inspected my car replaced 4 coils and advised I had buckled rims. But why didn't it shake all the time if it was buckled rims. I sought help from the auto electrician, I was still blaming cruise control, he replaced the other 2 coils but next highway drive it got way worse. The light vibration turned into a violent shudder. My husband starting blaming the brakes. Long story short, the ABS was sticking after being applied to cancel cruise control. As long as I didn't use the brakes, rather used the + & - or turned cruise off, I didn't have a problem. Solution: The Brake Booster has been replaced and my baby is a pleasure to drive again. Oh and, Ralph Wiggum, it may be a common and well know issue now, but I wish Ford had known about it 2 years ago. And Ford told me they have only just recently received a service bulletin and instruction about this fault.
