Service bulletin PIB 495

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

Daimler Trucks North America LLC, on behalf of its wholly-owned subsidiary, Freightliner Custom Chassis Corporation, has issued field service campaign SF546AB. In response, Newmar is publishing PIB 495. Issue: On certain coaches, a check valve is missing on the auxiliary air tank, causing the tag axle steer tires to remain in a turned position when stopping the vehicle during a turn and shifting into reverse. In addition, some of these vehicles also require an air line retrofit.
