Ok, I think I know the issue making the rattle. I dropped mine off at the dealer today to have a new roofline installed which they said "could" "possibly" "maybe" fix the problem. After they took the roof liner down to install the new one they discovered a weld that cracked! they did not exactly say where but said it was a bracket from the frame to the vista roof. So the cracked weld could not be fix there they have to send my edge out to body shop so they can re weld the crack. The thing that really gets me is that the first time i dropped it off they said they would drop the roof liner and I'm guessing they never did otherwise they would have found it the first time i brought it in. Im just gad they found a problem, and hopefully it fixed for good. They will have my edge for about a week.
