I have a 2017 Outback 3.6R.
I have a 2017 Outback 3.6R. OEM battery started to become less reliable early 2020 and needed multiple jump starts. Even after a long drive, just a few days without driving was enough to make the battery too weak to start the car. I got an aftermarket battery since I don't trust the OEM now. However, I'm concerned by the offline fuel pump test. I've caught it running way more often than should be needed. Daily tests? Multiple days in a row when I haven't driven? Why? Could this be part of the phantom drain?
