I got a notification yesterday morning that a new firmware upgrade was available. I loaded it at 6:30 am yesterday. Within three hours, I lost 3 miles of charge. The car automatically started recharging and recharged to 247 miles of range. I just received a notice, right at 26 hours from yesterday's full charge, that the car was recharging with 233 miles. That is 14 miles in 26 hours. The car has not been driven and is plugged in. It is a 2015 85D with 5K miles. Ordinarily I had seen between 2 - 3 miles per day loss.
