The issue for mine ended up being a steering rack that had been over torqued in the factory. Once the car was warmed up and at highway speeds, the "stiction" problem would rear its ugly head. At speed, the amount of electric assist drops off (as it should for better steering feel). It's when that assist drops off that there is not enough umph to overcome the slightly too tight situation in the rack.
It may take Ford a little while to own up, but they will. Just be patient and take your new gem into the dealer.

Oh, and ...
Great description, and makes sense that the assistance drops off at speed, so if there is mechanical resistance you would notice it more. I wonder if this resistance will reduce once I get more miles on the clock?
