Seat Belt Buckle Stuck in the Locked Position
If the seat belt cannot be latched, the bus may be operated without the seat belt being used, increasing the risk of injury in the event of a crash.
Adient will notify the bus manufacturers that purchased the seats with the defective seat belt buckles and will replace the buckle housings, free of charge. The recall began on August 15, 2017. Owners may contact Adient at 1-734-254-5000.
