NHTSA's recall notice
As NHTSA's recall record states it for campaign 26V388000.
Defect description
Daimler Trucks North America, LLC (DTNA) is recalling certain 2027 Thomas Built SAF-T-LINER HDX2 school buses. Front and mid-body interior joints may have been manufactured incorrectly, resulting in insufficient joint strength. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 221, "School Bus Body Joint Strength."
Safety consequence
A school bus with insufficient joint strength may not adequately protect passengers in a crash, increasing the risk of injury.
Manufacturer remedy
Dealers will add fasteners to secure the joints, free of charge. Interim notification letters, notifying owners of the safety risk, are expected to be mailed July 2, 2026. Additional letters will be sent once the final remedy is available, anticipated in August 2026. Owners may contact DTNA customer service at 1-800-574-0712. DTNA's number for this recall is F1034.
