NHTSA campaign 22V510000 · 1,806 units potentially affected · filed Jul 19, 2022

What's wrong

Daimler Trucks North America, LLC (DTNA) is recalling certain 2014-23 Thomas Built Buses HDX and 2014-22 EFX school buses equipped with 39-inch S3C seat frames and 3-point flex seatbelts. The passenger seat frames may crack and rotate from fatigue.

Why it matters

Cracked passenger seat frames may not adequately secure passengers in the event of a crash, increasing the risk of injury.

The fix

Dealers will secure the seat frames with brackets, free of charge. Owner notification letters were mail December 4, 2023. Owners may contact DTNA's customer service at 1-800-547-0712. DTNA's number for this recall is FL946.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
