Service bulletin RSB484

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

Spartan Motors has decided that a defect relating to motor vehicle safety exists in specific motorhomes built on Spartan chassis. In response, Newmar is issuing recall NHTSA # 17v 413. Issue: On certain motorhomes, the drive gear on the fuel pump may spin loose on the drive shaft, resulting in loss of pumping function. If this occurs, the engine may stall without warning and cannot be restarted. An unexpected engine stall without the ability to restart may increase the risk of a crash.
