Was idling in a parking lot and the warning triangle appeared with a BMS_a035 error. Drove home, battery started to make popping sounds as if it was supercharging, said it could not sustain the load so was shutting off unnecessary things, and several other errors appeared then disappeared quickly before I could get a picture (though guessing they logged). Checked the energy consumption screen and there was a period when it was well in excess of 900 Wh/mi (attached) valid at the time I was idling in that lot, then returned to normal. Scheduled a service appointment but first one was Oct 1. Any thoughts on how to proceed?
