The rattle may not just be coming from the cargo cover....thats what I thought, so I removed it....still had the same rattle. I've taken it in once to get it fixed (same time as the "other" rattle in the door/window area). The cargo area rattle is turning out to be the toughest to deal with. They tightened down some of the panels back there....it worked...for a day! I'll be taking it back in on Monday for a second attempt at the "cargo rattle"! When I told the SM that the cargo rattle was still there, even "he" said, "Yeah, thats going to be a tough one....just bring it back in..."
