GM has to fix it but it still matters in the meantime. It would be nice to know if there are any mitigation strategies. I haven't had the issue since having the battery replaced seven months ago. Is it my behavior or could there be some difference in hardware/software even within the 2019 model year? We don't have info on build dates, EVSE brands, etc. Maybe there's a pattern. All that said, we also don't have a good idea how common this actually is.2017-2018 are likely the same.
There were changes to 2019 for setting charge level and who knows what so they’re not the same. It doesn’t matter anyway because GM has to fix it, not us.
