Hey guys, just wanted to know if anyone else is experiencing rattling from the left and right defogger vents. It typically rattles on a cold start, low RPM, and rough road. It especially happens when it is cold outside and it seems to go away when it is hot. I'm assuming the plastic is expanding and contracting. In brought it to the dealer and they said that they can't fix a problem that comes and goes. I'm currently waiting for a "field engineer" to visit my dealership.
