The defect
Daimler Trucks North America LLC (DTNA) is recalling certain 2015-2019 Thomas Built Buses Saf-T-Liner C2 and Saf-T-Liner HDX school buses, equipped with certain S-Series and K-Series Titanium Wheelchair Lifts, models K200, K201, K550, K551, S200, S2201, S550 and S551. The wheelchair lift positioning input cam may fail while the lift is in use, allowing the platform to travel higher than the vehicle's 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.
