General Motors is recalling 131 2016 model-year Cadillac CT6 sedans because of a problem with the front-passenger seat belt, the National Highway Traffic Safety Administration reported.

The recall covers vehicles manufactured July 21-22 of this year. In these cars, the bolt that connects the front passenger seat belt webbing to the seat’s anchor plate may be missing, NHTSA said.

Without the bolt, the seat belt webbing may detach from the seat anchor. If this occurs, the seat belt “may not properly restrain the front seat passenger in the event of a crash, increasing the risk of injury,” NHTSA warned on its website.

To resolve the issue, Cadillac dealers will replace the existing front-passenger seat belt webbing anchor bolt — or install a bolt if it’s missing — free of charge. NHTSA recommends that occupants not sit in the front passenger seat until the recall remedy has been performed.

Vehicle owners can reach Cadillac customer service at (800) 458-8006. GM’s number for this recall is 16035.
