## 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.
