I have been waiting for an update to fix this, but a ~quick~ search shows no one has made this complaint yet. So how could it get fixed? I often return to the Model 3 before my spouse and the infotainment and climate turn on when I open the passengers side door, but when I sit down and close the door it all turns off. The seat sensor works, if I unbuckle with the car rolling the seat belt nag kicks in. If I stay in the passengers seat after my wife parks and leaves there is no issue. I can use the app to turn the climate back on, but cannot get the infotainment to come back unless I open the door. I know, first world problems, eh?
