I am not sure if this has happed to anyone. It was about -5 C. My model 3 has completed its charge cycle. I am ready to leave. My car is unlocked. I press the button on the charge cable, I can hear the cable lock mechanism click trying to unlock but it does not and I was unable to remove the cable. I tried to unlock using the phone up, the clicking sound continued. There were messages on screen saying it may be frozen or there is a malfunction. I took a hair dryer to the charge port for about 5 minutes and then it finally unlocked. Has this happened to folks. What to do if this happens again and I do not have a hair dryer close by. Is this a problem that I should report or bad design? Im 3 weeks into owning my Model 3 and appreciate any advise that comes my way.
