Hi all. New guy here. Question for you...Our 2013 Equinox was driven to store working fine, came out and would not start. Dash lights working but nothing from turning key. No starter clicks etc. Tried jump start, nothing changed. Took it to a general service place. They said the battery had a steady drain and battery had a dead cell, 10.8 amps. Since it was old anyway OK'd putting in new battery. Still no change, same symptoms. Guy checked every fuse, relay and could not find the source of battery draw. Suggested Body Control Module and to bring it to a dealer. Dealer has had it for several days and can't answer why it is drawing . Said it is not the BCM however. Has anyone experienced such a sudden, mysterious no start issue?? Thanks!
