I'm not aware of any vehicle that logs which circuits are active, especially when "off". How old was the battery? Even ones maintained well have a limited lifespan, and I expect the majority of the damage to occur on dealer lots as people open doors and leave them open without driving the vehicle long enough to top up the battery.

I certainly wouldn't take a car to a dealership over a 12v battery issue. Plenty of battery shops will load test it for free (I bought a load tester on sale for like $15), and will offer better pricing for a replacement.

Good work going straight to the problem!
