Arrived at a supercharger yesterday & plugged in to charge. After about 25 minutes of charging, charging stops, I get a message saying that car unable to charge, unplug & try again. Went to the charge port & saw a red ring. I unplugged then plugged in again. Charging starts up like normal for about a minute & I get the same message again. I tried again & again with the same problem. I decided to move to a different stall & all is fine. Anyone here experienced this problem before?
