Nothing electrical has been added. The service advisor said when the car was towed in last night, the rear hatch was not fully closed. I did open it to get the towing hook out and may have not closed it all the way. They think I could possibly not be closing the hatch all the way causing the interior light to stay on all night and draining my battery. Maybe i'm just a du-mass...
