Refreshed facia S60D delivered 9/17/16. Kept in a heated garage. Always plugged in when garaged. It has never overnighted without being plugged in. Updated to 75D a month ago. Last night I couldn't summon the car out of the garage, and when I got in the 12V warning was on. I understood that after some trouble in 2013 these issues were under control. Now I've got a 220 mile round trip drive to get a replacement. (Not complaining about the drive, I knew where the service center was when I bought the car.) I haven't seen reports after this short a period of time. Is this normal?
