Service bulletin TSB 427

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 Chassis, Inc. has decided a defect which relates to motor vehicle safety exists in certain motor home chassis. Newmar has provided the list of coaches affected by this Spartan Recall. NHTSA # 15V 492 TC# 2015-345. The control module for the air suspension may experience a loss of power resulting in the air suspension not being able to achieve ride height. If the ride height of the suspension is less than specified ride height, negative impact to roll steer could occur. This could cause the vehicle to be difficult to control and increase the risk of a crash. This could occur without warning.
