Anybody have any thoughts out there?
To me, it's clear that the car is not sleeping properly (or waking up repeatedly) throughout the night due to a faulty module or something. Unfortunately, it's hard to troubleshoot this as a DIY. Not sure what good dealerships there are in Harrisburg but hopefully you have a good one who is capable of learning what module is failing instead of hiding behind the "unfavorable driving profile" excuse...

have had a high battery drain and reset clock warning intermittently the last 4 months. Finally had a CEL last week along with the high battery drain warning + reset clock 3x in one day (usually only once a day prior to this day). Techs kept it for 2 days for diagnosis, said they found nothing and just replaced the battery....fingers crossed...
