Some 2015-2023 Transit vehicles may exhibit front seat safety belts that do not extend or retract properly or may exhibit an abnormal noise. Verify if the vehicle has been modified, in particular if a bulkhead partition between the front seats and cargo area has been added to the vehicle. Fasteners or holes in the lower b-pillar are indicators that the seat belt retractor mechanism could have been compromised. If diagnostics lead to retractor replacement, inspect for drill or screw holes in the retractor housing. Damage to the seat belt retractor caused by a vehicle modifier is not warrantable.
