What's wrong?
On 2015-2019 Ic Bus Cesb and Casb school buses, the wheelchair lift uses a positioning input cam to control where the platform stops as it rises. The lift is meant to bring a passenger from ground level to the bus floor height, then hold the platform at the correct level for boarding.
On affected buses with Ricon S-Series and K-Series Titanium wheelchair lifts, that cam can break while the lift is in use. The recalled cam is injection molded plastic, while the remedy cam is machined aluminum. Navistar reported that the exact cause of the cam break was not determined, but a broken cam lets the platform travel higher than the vehicle floor height.
There is no warning sign before failure. A driver, attendant, or passenger will not have a reliable cue that the cam is about to break before the lift platform moves past the intended stop point.

- Keep passengers off the wheelchair lift until the cam replacement is complete.
