Affected Units:: 6,591
The involved vehicles do not conform to federal motor vehicle safety standard no. 209, "seatbelt assemblies". Although the seatbelts in question performed marginally with respect to the 5000 lb. Load requirement, additional testing confirmed that the anchor could fail, allowing either the anchor to slip over the hold-down nut or the anchor to separate into two pieces.
Dealer will inspect and, if necessary, replace seat belt assemblies without charge to owner.
Vehicle description: trucks. System: interior; seat belt anchorage assembly. Consequences of defect: in the event of an accident, these seat belts may notadequately restrain passengers and serious injuries may result.
