Spartan Motors, Inc. (Spartan) is recalling certain model year 2013-2015 Gladiator, DR, K2, K3, MetroStar, MM, and NVS vehicles manufactured December 14, 2011, to October 21, 2014, equipped with certain Wabco Quick Release Valves with Double Check. In the affected valves, the rubber diaphragm may be damaged by sharp edges on the valve seat ribs, reducing the available air pressure in the air tanks.
The reduced air pressure levels may reduce braking performance and/or the parking brakes could reapply, increasing the risk of a crash.
Spartan will notify owners, and dealers will inspect and replace the valve, free of charge. The recall began January 22, 2015. Owners may contact Spartan customer service at 1-517-543-6400. Spartan's number for this recall is 14021.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
