Pathetic service on Ford's part. By this time a district service engineer should have gotten involved and offered her a buyback or a replacement vehicle. I'm a little surprised that the dealer wasn't able to nail it by now, as it sounds like an isolated case and thus a problem with this particular vehicle and not a platform problem, but either way if I were the customer I would not be comfortable getting a vehicle back that has failed so early and so greatly.
Perhaps the media attention might provide some motivation for them...
