Subaru Battery Drain due to shutdown of 3G net

Recommended Posts

Later models of Subaru has the Starlink system using the 3G and possibly also the 2G nets by the telecom operators and it will start to drain the battery when those networks are unavailable. The offending module is the so called DCM (Data Communication Module) that's taking care of the telematics.

I actually got that info from here.
