Problem
Daimler Trucks North America, LLC (DTNA) is recalling certain Thomas Built Buses 2023-2026 Saf-T-Liner EFX and Saf-T-Liner HDX school buses. The heater hose clamps may not have been tightened properly, causing the hose to disconnect and leak heating coolant inside the passenger compartment.
