Just received delivery of my performance S 2020. This would be my 3rd model S - and the “raven” is a HUGE improvement in all aspects. However, I have a problem charging at home with my level 2 charger (Juice Box), which has been working fine with my 2015 P85D. After plugging in the car displays “maximum AC charge rate reduced” message and then “AC charging interrupted” message - and the car stops charging. Tesla tech isn’t aware of firmware changes that would interrupt such simple charging operation. I tested the charger again today with the older S and it worked flawlessly. Anyone with similar experiences? Suggestions? Thanks much!
