After being on the charger and sleeping for days, my 2021 Model 3 will eventually get itself into a mode where it continually runs repeated charging cycles and will never go to sleep. I figured out before that if I unplug the charger and plug it back in, it'll go to sleep after a few minutes... until the next time. I am using a J1772 charger with the adapter. Don't know if that has anything to do with it. Anyone have any ideas? This is just the most recent incident. The one before: it stayed draining about 1kW every few hours and then recharging and continued doing that for 3 days before I had the idea to unplug it and plug it back in. Before that, no sleep cycles in 3 days but as soon as I unplugged the charger and plugged it back in, it went to sleep within 15 minutes and stayed sleeping for a day or two, until the next time I drove it.
