Nothing major, just noticed that the air conditioning wasn't working....I'm happy to have the Model S P100D loaner overnight, but I really want my car instead! I've put about 150 miles on the Model S loaner and I'm in love with the screen behind the steering wheel. I am really hoping that I don't miss it on my 3. BTW, "Ludicrous Mode" is bonkers. If you haven't experienced it....you need to find a way to do so.
