While on vacation, my 2006 Lucerne sat for a couple weeks. When I tried to start it, the battery was DEAD. My dealer''s service mgr tells me, because of all the electronics (On Star, etc.) I need to run the car every 2-3 days to keep the battery up. I find this hard to believe. Hard to believe the battery can not hold a charge for two weeks.No mention of this in the owners manual. Anyone have experienced this? I welcome any comments.
THANKS
