NHTSA campaign 97V135000 · Part 573 safety recall report

Spartan Motors, Inc.: Suspension › Front › Springs › Air Suspension System

Spartan Motors, Inc. reported this defect to federal regulators on Aug 18, 1997 and put the number of vehicles at risk at 262. The repair is free for as long as the recall stands.

The defect

VEHICLE DESCRIPTION: CLASS A MOTOR HOME CHASSIS EQUIPPED WITH INDEPENDENT FRONT SUSPSION, WHICH UTILIZES A NORGREN VALVE AND NEWAY PILOT AIR CONTROL VALVES. THE PURPOSE OF THE NORGREN VALVE IS TO EXHAUST THE AIR SUSPENSION WHEN THE DRIVER ACTIVATES THE VEHICLE JACKS USED TO LEVEL THE VEHICLE FOR OVERNIGHT PARKING. THE NEWAY PILOT VALVE IS USED TO SPEED UP THE TIMING OF THE AIR EXHAUST. WHEN THE VEHICLE IS IN A DYNAMIC CONDITION, THE AIR SYSTEM PRESSURE CAN SEND SPIKES OF UP TO 230 PSI. THIS EXCEEDS THE PRESSURE RATING OF THE NEWAY PILOT VALVE CAUSING THE VALVE TO FAIL AND ALLOW THE AIR SYSTEM PRESSURE TO EXHAUST UNCONTROLLABILITY.

The risk

IF THERE IS AN AIR SUSPENSION FAILURE, IT COULD LEAD TO VEHICLE HANDLING PROBLEMS AND A LOSS OF VEHICLE CONTROL.

The remedy

DEALERS WILL MODIFY THE AIR PLUMBING TO REMOVE THE THREE (3) NEWAY PILOT VALVES (TWO FRONT SUSPENSION/ONE REAR SUSPENSION) FROM THE AIR SYSTEM. THE NORGREN VALVE WILL BE FULLY UTILIZED TO REPLACE THE VALVES IN THE FRONT SUSPENSION AND A MIDLAND VALVE WILL BE USED IN THE REAR SUSPENSION.

What this page is, and what to do next

A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.

This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 97V135000.
