## 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.
