Maximum Percentage Charge Fluctuating


Sep 20, 2021
NW Ohio
Took a short trip this afternoon and plugged our 2021 S into the Tesla Wall Connector when er arrived home. We have always kept the maximum set at 84% and it has worked just fine. Today as soon as I plugged it in the message on the screen said the charge was at 72% and it was stopping the charge since the set point had been reached. I reset it and it then charged to the set point (85%) and stopped. While I was sitting in the car trying to become more familiar with the computer it started charging again and went up to 87% before I readjusted the shut off point again. Any thoughts?

My Tesla Phone app (or the car) has a bug where it sets the charging set point and the charge rate differently from what is in the car, and it changes itself from one login of the app to another. Nothing too serious, but how do they program something to behave so erratically. Check your phone.
