Have the exact same issue with 28.2Ugh, I actually had 26.2 and had this happen all the time. Car kept starting and stopping charging like every minute when it hit the max charge I set it at. Called support and they saw the same so they forced an update to the car... 28.2. Looks like the update didn’t fix the issue. let us know if you hear anything else! I’ll post back if .2 fixes it.
