Consumer Description
Car battery dies after the vehicle sits for longer periods (approximately 2 weeks or more?). Roadside assistance has tested battery twice after jumping the vehicle and stated the battery is still healthy. Various Subara owners report similar situations in online forums, and the culprit seems to be a design flaw where the DCM module is trying to connect with the obsolete 3G cellular network, causing a parasitic battery drain.
