So magically ESS started working this morning for the first time in weeks and my voltage reading fell from 14.5 ish all the way down to 12.5 - 13 with no change in driving habits. Weird. Maybe the new main battery charged the aux and is working after a few days of drivingMy dealership last week replaced the main battery due to this issue and of course, days later with a good amount of highway driving has not fixed the issue. ESS still has not worked in several weeks. They also mentioned TSB 19-108-19 which I can not find any details on. Needless to say I'll be going back to hopefully get the aux battery replaced which is probably the real issue. It sucks.
