While at my service today, I mentioned to the service manager about the slight rattle I'm beginning to notice (Kitty Paul, I DON'T want to hear your bitchin'). I stated it sounded like the cargo cover. They took off the cargo cover on their tests-they stated it still rattled and don't believe it has to do with the cargo cover, although they do admit it's making a slight rattle. He said they couldn't determine the cause/source of the rattle, but said they would be happy to pursue it further at my request, especially if I notice it getting worse. He thought it may have something to do with the rear suspension/bushings(?)
