NHTSA's summary

This bulletin announces a design change to the air vent grille located in the lower portion of the trunk (or cargo) area. The shutters of the vent grille are designed to open briefly and relieve cabin pressure when the doors are shut with the windows fully closed. The vent grilles have rubber ?shutters? which occasionally, may catch on the frame (case) portion and not close properly allowing outside air / odor to enter the cabin.
