FYI: This is what happened to me today: Yesterday the charge port started misbehaving; showing that it was open while I was driving, though it wasn't. When I arrived home the charge port was reluctant to open, but finally did and I plugged in the charge cable. Today (after a full charge overnight) the charge port was still showing open on the dash even though it wasn't. Worse yet, when I returned home the charge port wouldn't open at all. Call to Tesla Technical Support, who told me that pushing in on the rear of the charge port would force it open (it has a magnetic catch). Problem is, even after I get the port open the car won't accept the charge cable! No white/blue light, and can't insert the plug. I'm freaking out (nearest Service Center is 120 miles away) and Tesla tech support is puzzled. The solution: Reboot the Model X. Tesla tech support says to power down the car, wait a bit, and power up again. And everything is fixed; charge port door, dashboard indicator, and most importantly the charge cable is now accepted. I'm reminded again that the Tesla is actually a PC on wheels.
