I have a relatively early car, VIN 2350 and about 2500 miles on it now. This has happened to me a couple of times and I haven't found a thread on it yet so thought I'd post my first thread. At night I'll frequently put the car on a 110V 20A circuit just to charge a few handful of miles overnight and so it's easy to warm it up in the morning. Twice now I've reached the charge limit I've set and when I go to unlock the charge port, I can't. I'm stuck, unable to remove the charge plug (the mobile one Tesla furnishes). If I have to stop charging BEFORE I reach my charge limit, I simply stop charging and unlock the port and all is well. There are ways around it but it seems I should be able to simply unlock the charge port once the car is "fully charged" Am I missing something? Oh, software update on the car is still at 50.12.
