pretty common rattle, i have it too. its because there are 2 wheels in the door regulator assembly, one is nylon and one is metal, and the metal one gets lose and starts making noise. if youre under warranty take it in and tell them youll drive and replicate it, and they should pull out the window regulator and fix the issue.
