The butt sensor also complicated attempts to open the charge-port door. When the supplied mobile charge cord is already plugged into the wall on the other end, holding it near the charge-port door pops the door open. No problem. But a Level 2 charger doesn't do this; you must release the door from the touch-screen. If you don't do so ahead of time, there's no release on the key fob, like the Chevrolet Volt has. You can't reach in and press a button on the door, or even pull a crude lever like the 2011 and 2012 Nissan Leaf have. You have to sit in the driver's seat, wait for the car to turn on and then press the appropriate button on the center touch-screen. Sometimes it opens on the first try, sometimes it doesn't. Likewise for the neat exterior door handles: They remain flush against the body but motor out when you tap them. Usually. Tesla says an option will make these handles emerge automatically, or "present," if you step close with a key fob on you. This feature, once again, is coming.
