I am now a solid month into the same wait. I escalated yesterday via the Model S owner user account, and got an emailed response within a few hours that was frankly a bummer. Same story as
@bonnie got and posted above, which is the same story I was given by the Tesla phone rep two weeks ago after I waited 53 minutes on hold. Patently ridiculous. I'll be absolutely stunned if the 'executive escalation' actually does anything. Based on the posts above, it sounds like I should have mine moved by Wednesday of this week, otherwise what Tesla is currently saying is to email the CEO and the squeaky wheel will get the grease. Insane. Love my car, but this situation should have been built into the configuration/ordering web interface that was oh so easy. I shudder to think of the Model S and X owners who are currently having the same hassles with routine title transfers, just because a bunch of Model 3 owners have now shown up and clogged the manual gears. (How on earth was this activity manual even prior to Model 3's arrival?)
