Service bulletin 23KWK

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

In a severe collision, the ICP bar may fail allowing the seatbelt to slip, increasing the risk of injury. This bulletin will be updated when repair parts and procedures become available.
