I'm retired. and my 2017
I'm retired. and my 2017 Outback now (April 2021) has only 10,750 miles ---- I have had the battery replaced twice. -=- both times by AAA's mobile service. The AAA person was not surprised by the battery failure. I'd guess that there is some sort of continual drain on the battery from the vehicle's electronics. Is there an aftermarket battery condition meter available?
