Had not closed trunk completely and found battery dead 2days later. Tried to jump battery and it wouldn't take. Had car towed to dealership and was told the B+ cable was bad and had drained battery cells (battery was purchased June, 2012) and I would have to have both battery and B+cable replaced. Battery: $190.00. Cable: $165.00.
dash lights abs,anti traction,light lights up , I guess due to faulty battery cable
