I just heard about a recall on several models of Subarus, including Outbacks. I think it was for model years 2005-2009, and had to do with the brake lines deteriorating. I know a lot of CampInn owners have Subarus, so if you don't already know about this, it would be a good idea to contact a dealer for the fix.
EDIT: More than just those model years. See here - Subaru Recall info
