Service bulletin RSB 474

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 USA, Inc. has decided that a defect relating to motor vehicle safety exists in specific motor homes built on Spartan chassis. In response, Newmar Corporation is publishing a recall: NHTSA #16V 810 TC #2016-543. On certain motorhomes, wires in the throttle circuit were not shielded properly during manufacturing. This could result in an incorrect throttle setting above or below the commanded throttle setting/input, which may result in a loss of throttle or inadvertent acceleration of the throttle. This condition, depending on the driver's reaction and traffic conditions, may increase the risk of a crash and/or property damage.
