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.
