Defect: Bentley Motors, Inc. (Bentley) is recalling certain 2012-2018 Bentley Mulsanne vehicles. In the event of a crash, the rear seat belt anchor may detach from the vehicle. As such, these vehicles fail to comply to Federal Motor Vehicle Safety Standard (FMVSS) number 210, "Seat Belt Assembly Anchorages."
Risk: In the event of a crash, if the rear seat belt buckle detaches, the seat occupant would have an increased risk of injury.
Fix: Bentley will notify owners, and dealers will improve the strength of the rear seat belt mounting by adding an additional reinforcement panel to the body structure, free of charge. The recall began March 7, 2019. Owners may contact Bentley Customer Service at 1-800-777-6923. Bentley's number for this recall is RE 19/01.
