On certain vehicles, the bush installed on the outer handle for the rear door was reused when the handle was dismantled at a dealer to adjust the door opening, due to insufficient information on the adjustment of the left and right rear doors opening. If the vehicle continues to be driven with such reused bush, the bush may be damaged, causing the rod connecting the outer handle and the door lock assembly to come off, in which case the window wound down during driving could push the rod, resulting in the door opening.
