My 2015 Forester lost its power steering for 24 hours, then it came back (that was 24 hours ago). The dealer checked it out and concluded car needs a ps module. $570 if I have it installed. The thing is...they sounded really uncertain. Has anyone experienced on again/off again powee steering in the models with electrically powered steering? If it matters, it was a very hot day when it went out...not that that's ever been a problem.
