    I'm having an issue charging at home. Charging is very erratic, from working fine to not at all.

    I had solar city install a NEMA 14-50 outlet and at first it was working fine, would charge up to 40 amps, 20-25 miles per hour. Over the last month the charging has been stopping and when i go to see what is happening I see multiple different messages ranging from 9.6V battery issue, cable error to "car needs service." I never have any issues charging at my workplace (where granted the electricity is much more powerful than at home, its a warehouse where we are set up to charge multiple forklifts simultaneously) or at super chargers or public parking lots.

    The first time Solar city changed the breaker, that worked for 1 day. The second time they said its a car issue and not an outlet issue and got in touch with Tesla and i followed up with Tesla directly. Tesla gave me a new charging cable but that did not work either. I got a friend with a Tesla to come by and see if his car would charge and it wouldn't so i know its an issue with my house and not the car but when Solar city look at it everything looks fine on their end.

    This is the last email i have from Solar city: "Coincidently, I was at another customer's home yesterday who is having the very same issue. I am investigating the issue with LADWP and SCE, as well as Tesla. This is definitely perplexing. Please let me have a few days to gather some information and I will get back to you."

    Has anyone encountered anything similar?

    I found a similar local issue with another Tesla owner where the receptacle used did not have a steady ground. Traced it to a loose terminal inside the receptacle that didn't permit a steady ground. I opened the receptacle, closed the ground clip just a bit, then it has been steady since.

    One other thing to look at is the LED status on the UMC and the LED status on the car.
