The customer may experience a knocking sound from the instrument panel area near the A-pillar.
An audible buzz, squeak, or rattle (BSR) or knocking sound may appear to be coming from the instrument panel (I/P) area at or near the front leading edge of the A-pillar. The noise may actually be caused by an improperly adjusted hood hinge. The hood hinge can be checked in the closed position by grasping the hood near the rear corners at the hinge and lifting up and down. If excessive motion and/or a knocking sound is produced or the customer describes the symptom, perform the Repair Procedure.
