16048 -Service Update. Certain vehicles may have a condition in which the over-mold polymer material on the seat belt latch plate of the rear outboard seat belts may not allow the latch plate to be properly inserted into the buckle, or may require excessive force for the buckle to latch. The customer may be unable to buckle the seat belt. Dealers will inspect, and if necessary, replace one or both rear outboard seat belt assemblies.
