Official summary
Some customers may complain that the clip on the rear end of the rear beltline molding is loose and the molding is slightly lifted up. Due to the poor shape of the clip claws, the fitting force to the door body may decrease while in use. To eliminate this concern, the clip has been enlarged in the horizontal direction to improve the fitting force against the door body.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
