Gillig LOW Floor Recall 17V263: Suspension Air Loss Can Cause Sudden Bus Drop

NHTSA campaign 17V263, reported April 19, 2017, 2,604 vehicles potentially affected.

What this recall means for you

Certain 2015-2016 Gillig Low Floor transit buses have suspension kneeling modules where snap rings on the solenoid valve pistons may not have been fully seated during assembly. This can affect suspension air bag pressure and vehicle height.

If air pressure is lost while driving, the suspension can drop abruptly, which raises the risk of a crash. Air pressure can also be lost during servicing, creating a 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 correct groove. The repair is free at an authorized dealer. Owners can contact Gillig customer service at 1-800-735-1500, and you should check your VIN for open recalls.
