The defect
Collins Bus Corporation (Collins Bus) is recalling certain 2012-2018 School Buses, equipped with Ricon S-Series and K-Series Titanium Wheelchair Lifts. The wheelchair lift positioning input cam may fail while the lift is in use, allowing the platform to travel higher than the vehicle floor height.
The risk
If the wheelchair lift platform stops above the vehicle floor, the wheelchair user can tip inwards toward the vehicle when exiting the lift, increasing their risk of injury.
