Anyone else have this issue? Most nights it takes one-two minutes twisting the mobile connector (MC) within the charge port to get the car to recognize the connection and start recharging. Twice during the four weeks I've had my Model S I couldn't get it to work at all, and went a night without charging. But it worked the next day. I've confirmed that I can use public J1772, so I suspect a flaky MC. But I'd like some confirmation before contacting support.
