New Tesla S 90D delivered December 2016. After every firmware update, the battery charge level drops significantly about 20-30% compared to before the update while the car is parked and plugged in. An hour or 2 later, the charge level gradually goes back up to baseline. If the car is plugged in, it overrides the charge limit and end up at 100% even if it was set to max out at 80 or 90%. If the car is not plugged in, charge level eventually goes back to what it was before the update.
Service center does not know what's going on. They called Tesla engineers and states that this is a normal behavior with the car trying the re-read battery capacity.
Has anyone experienced a similar issue?
Thank.
