Gillig LLC (Gillig) is recalling certain 2015-2016 Low Floor transit buses equipped with Norgren-brand suspension kneeling modules. The suspension kneeling modules on these vehicles have snap rings on the solenoid valve pistons which may not have been fully inserted and seated during assembly, potentially affecting the suspension air bag pressure and the vehicle's suspension height.
An unexpected loss of suspension air bag pressure while driving would result in an abrupt reduction in suspension height, potentially increasing the risk of a crash. A loss of suspension air bag pressure could also occur during vehicle servicing, increasing the risk of injury to maintenance personnel.
Gillig will notify owners and pay fleets to inspect the front and rear kneeling modules. A snap ring reset tool will be provided free of charge to permanently seat the snap ring in the intended groove. The recall began on June 2, 2017. Owners may contact Gillig customer service at 1-800-735-1500.
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.
