The third row seat can experience rust at the seat anchor mechanism mounted to each rear wheel well. As a result, the seat may not fully latch into its seating position. If the vehicle is hit from the rear, an unlatched seat may increase the risk of injury. Dealers will install new third row seat latch striker mounting brackets to correct this concern.
