There is a very simple solution to the squeaks and rattles. Go to your local craft store...hobby lobby, michaels...ect. Buy some felt, colored to match your interior of course. Fold it up long ways, and stuff it down in between you dash and windows, from dash speaker, to dash speaker. Stuff it down until you cant see it. Use a scewdriver, with the tip taped up so you dont scratch anything. This will solve all the rattles.
I had the same issues with mine, and this took all the rattles out. Completly silent now. Mine took 5 sheets of the felt and it costed me $1.95 for the felt......lot less than having the dealer do the exact same.
Even if you are still under warranty, this took me less than 5 minutes and less than the amount of gas to take it to the dealer....
Hope this helps.....
