Reading through the S's owners manual it says: +++++ Hold down the rear trunk button on the key for 1-2 seconds (applicable only if Model S is equipped with a motorized charge port). Note: If you do not insert the charge cable into the charge port within a few minutes after opening the charge port door, the latch closes. +++++ Holding down the trunk button always opens the door. Going by the above that would seem to indicate the door is motorized. But once open, no matter how long I leave the port door open it never closes on it's own. So, is it motorized and I'm missing something? Or not motorized?
