Nov 2016 - supposedly this is a "new" thing. My car got damaged while waiting for service (sounds like this happens a lot, WTF?), and since there was an open ticket for repair, even though I did get possession of my car back until the service and repair could be completed, remote access had been disabled by Tesla. Unfortunately they DID NOT INFORM ME of this, I was going nuts deleting, reinstalling, resetting, etc. By reading this thread I see that it is maybe not a new thing, yet another fib told to the customer.
Just wondering how they are going to handle things once the tide swells with Model 3 owners in a few years. If not for this site we would all be in the absolute dark instead of just wearing very dirty glasses.
