    Hello,
    Since I took delivery of the car last Thursday, I always have scheduled a charge for 3am. Using a Tesla's HP Wall Connector - but for some reason, when I woke up this morning to preheat - the car was not charged. I went to the car, and it was making some sort of Clicking noise.....by the charge port.
    I opened the front driver side door, and the car began to charge... i didn't do anything else....
    What could be the issue???

    Hmm. almost sounds like the HV battery contactor wasn't closing from the charge request but did from the door request. Very strange. Have you tried charging again since?

    Well the contactor closes (makes contact) when you open the door on Teslas and it's supposed to close when you initiate charging as well. Perhaps whatever gives the signal to close the contactor when charging isn't sending the signal on your car? Does this happen consistently or just the one time? If consistent, did you try a different charging station? Perhaps something is wrong with your EVSA or connector on it.

    The older UMCs often developed a clicking issue. I think it was the button on the charge-cable-end making partial contact when not being pressed.
    I haven't heard/read about the issue in a long time, and I don't remember hearing about it with a wall connector, but it's one possibility.
    Doesn't explain the door event though.

    clicking like maybe the locking mechanism for the charge handle. the opening of the door allowed it to lock onto the charger okaying the charging to start?
