First, if you don't like how the dealer is treating you, ask to speak to the GM. Tell them what you're unhappy with, how you want it resolved and that you'll be complaining to Ford if your problem can't be resolved satisfactorily. If you call Ford's marketing department, they'll be happy to help you formally complain about the dealer.
Second, the mirror thing smells like an engineering problem, not a service problem. I haven't taken mine to the dealer yet for service, because Ford's engineers haven't told the techs how to fix the problem. So there's nothing they can do other than make sure the truck's put together correctly (which it probably is, since it's a common problem). It would appear that, on startup, the mirror memory/drive system is not able to sense the true position of the mirror (alternate: it starts driving it in the wrong direction and can never achieve the correct position because it's moving the wrong way. But I don't know the details of the position sensing/control system, so these are merely my best guesses.) Ford is likely now aware of the problem and they'll send some jr engineer to figure it out, which will probably take 8-12 weeks. Then begins the long and arduous journey of figuring out the best fix for production and how to roll it out to the already produced vehicles. My guess would be 2nd half of next year we might see a TSB for the mirrors.
