I took delivery of my Model S last Friday, and my Tesla App still isn't working (shows "No Vehicles Linked to This My Tesla Account"). After calling my Service ("call your DS"), DS ("call tech support"), and finally Tech Support ("wait a few days") - I'm starting to wonder who can actually get this to work? Each call to Tech Support has been them telling me to wait another day. The car still shows as "production complete" on the MyTesla site. Does anyone know who I can turn to in order to get the app working? I wonder if something is hung up because it was a demo/inventory car?
