Service bulletin 21V372

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 Shyft Group Inc. (Spartan Chassis) has decided that a defect relating to motor vehicle safety exists in specific motorhomes built on Spartan chassis (NHTSA #21V 319) based on Cummins recall (NHTSA # 21E 032). In response, Newmar Corporation is issuing recall NHTSA # 21V 372 and TC # 2021-303. On certain motorhomes, as described in Cummins recall 21E-032, the fuel rail assembly on the engine may develop leaks, which may result in an undetected prolonged diesel fuel spray. A leak involving spraying/misting fuel in the presence of an ignition source may increase the risk of fire.
