So we picked up a Model 3 Performance in December. Since we bought it something weird has happened maybe 5-7 times when charging at home. I charge to 90% every day at home, when I get the charge complete message from the Tesla App I unplug it because we also have to charge our Model S. The weird part is Model 3 continues to charge and the percentage/miles increase even though it is already unplugged!!
The increase has ranged anywhere from 3 miles to 10 miles. I can't replicate it and don't see any particular pattern when it happens. My charging set up at home is a 14-50 outlet with my UMC plugged into it. This behavior has occurred using our UMC 1 from our Model S charging at 40A and also our UMC 2 from the Model 3 charging at 32A. Its happened on various software versions too. No error messages in the car or error lights on either the UMC1 or UMC2. This has only happened when charging at home, has never happened when using a Supercharger.
This happen to anyone else? Can anyone explain why this happens? Should I have Tesla check it?
Car is great other than my 90% dropping from 264 miles new to 253 miles now.
