My charge port door rarely opens on command, even though I can clearly hear a click indicating that it's trying to open. The first time it happened was at home, and I just waited a couple hours and tried again, and it worked fine. When it happened again just before a road trip, I called Tesla, and they gave me a workaround - hit the back edge of the charge port door with the bottom of your fist repeatedly and with increasing force. That works well enough to get the door open. Tesla told me to clean the magnets, since this is usually caused by some sticky gunk getting on there, but cleaning it didn't fix the problem for me, and there is no gunk whatsoever. This has been happening now for about 3 months, on a 4 month old car. Eventually I'll take it in for service to fix it, but so far I'm getting by with the workaround so it isn't a top priority.
