I don't recall anyone reporting OBDC codes, so the lack of those isn't significant.
Print this thread and associated ones and take it with you to the dealer (or email it to them, if they're up to that). More information about the problem might help, and it will demonstrate that it's not just you, whether or not Ford lists it as a known issue yet.
In my case, the dealer was not driving it far enough or fast enough. I informed them that the problem arose after 40-45 minutes at 55+ mph. They took it on a few trips around town the first day and said they couldn't detect the fault. I once again informed them that it is a problem that manifests on the highway, not in town, so they said they would drive it again. They told me they drove it on a 120 mile round trip on the highway, plus another 45 mile round trip, plus 40 miles around town. The problem was the odometer showed only 88 miles, so they never took it on the highway long enough. It was really frustrating being lied to.
I informed them of the other people in this thread experiencing the same problem, but all I heard back was that Ford hadn't heard of it and that I probably wasn't accustomed to driving a car with a sporty suspension.
