Thomas Built Buses Saf-T-Liner HDX Recall 22V510: Bus Seat Frames May Crack and Fail to Secure Riders

NHTSA campaign 22V510, reported July 19, 2022, 1,806 vehicles potentially affected.

What this recall means for you

Certain Thomas Built school buses equipped with 39-inch S3C seat frames and 3-point flex seatbelts may develop cracks in the passenger seat frames from fatigue. The frames can also rotate, so the seats may not stay properly in place.

If a seat frame cracks and rotates, it may not adequately secure passengers in a crash, which increases the risk of injury. Owners should contact Daimler Trucks North America's customer service at 1-800-547-0712 and reference recall FL946.

The repair is free: dealers will secure the seat frames with brackets at no charge. Owner notification letters were mailed December 4, 2023. You can also check your vehicle's VIN for open recalls.
