I've been hearing a metal scraping noise when I turn left coming from the rear passenger side tire area. Today I notice a thin piece of metal (flat metal, 1/4 of inch wide, 6 inches long) hanging down and look under the car and it has poked through a plastic covering right in front of the tire. Any thoughts on what might have broken? Have pushed down on both sides of the car and notice no noise from the movement. Just want some direction and to make sure it's ok to drive in to a dealer.
