A snap-shot to the above Torque News piece.
Article quote:
"Can I disable my Auto Stop-Start?"
..."The Auto Stop-Start can be disabled on your new 2020 Subaru Outback, Forester, Legacy, and Crosstrek. It’s different for each model, and the problem is, on some models like Forester, you cannot permanently disable it. The system will always default to an ON position once you turn the car OFF. So every time you get back in your car, you have to manually disable the system again"...
The article goes on to say [sAE] the stop/Start feature fuel savings are real .. Oh well, that's progress .. Have a read.
