Alarm system mysteriously went off.
I have a 2016 Subaru Outback, 3.6 L. Last night the car was in the garage
(had been there many hours, unlocked) and the horn started honking and the
lights flashed as thought the alarm had been activated. By the time I found my
fob and got to the garage, it was just finishing its tirade and stopped. It
otherwise operates normally. Does anyone have a clue as to what happened?
