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.

Risk: 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.

SERVICE BRAKES, AIR:SUPPLY:HOSES, LINES/PIPING, AND FITTINGS

Gillig LLC (Gillig) is recalling certain model year 2014-2016 Gillig 29-foot Low Floor transit buses manufactured November 20, 2014, to February 11, 2016. These buses, equipped with disc brakes, have rear brake hoses that can rub chassis components and fray.

Risk: A frayed hose may leak air, causing the rear brake(s) to lock up unexpectedly, or fail to operate when the brakes are applied. Either scenario increases the risk of a crash.

EXTERIOR LIGHTING:BRAKE LIGHTS

Gillig LLC (Gillig) is recalling certain model year 2012-2016 Lowfloor diesel-electric hybrid vehicles manufactured March 6, 2012, to June 7, 2016.
