This was and is a real issue on the old Tesla roadster. And to some extent on the early model Ss..... on the newer cars they have a tighter DC-DC converter/charger system which has mostly eliminated this problem to a pure service item at the annual service.... but sometimes there are bad 12V batteries that do fail..... if this is any “consolation” in your search for a possible reason.......
