Certain vehicles do not comply with the requirements of CMVSS 209 - Seat Belt Assemblies, and CMVSS 210 - Seat Belt Assembly Anchorages. On some of these vehicles, the passenger-side rear safety belt may have been installed with an incorrect nut and bolt that may not withstand the loads required by the two standards. In a severe crash, the upper seat belt anchorage may separate. The effectiveness of the seat belt could then be reduced and the occupant could receive greater injuries. Correction: Dealers will remove the required interior trim pieces and replace the incorrect passenger-side rear seat belt retractor attachment hardware.
