Service bulletin B111216

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.

NHTSA's summary

The crankcase ventilation hoses may become brittle and break when they come in contact with hot engine components. One or more of the crankcase ventilation hoses are not FPM (fluoroelastomer) rubber material. The FPM rubber material is engine heat resistant. Or The plastic corrugated hoses are not fitted with the self-locking spacers. The self-locking spacers maintain an air gap between the hoses and the hot engine components.
