airbag rattle

unfortunately my mazda 3 on 2k miles has a new and very annoying rattle. its a rattle of high frequency (like a cell phone vibration). after some searching and careful listening i figured out that its a passenger airbag rattle (or something very close to it). does anyone else have the same problem? is something else rattling in that area? my concern is: if its the airbag, can the dealer fix it correctly? after such a fix will the airbag function properly?
