2023–2025 Thomas Built SAF‑T‑LINER HDX and SAF‑T‑LINER EFX school buses are affected; owners can recognize them by those model names and model years. The heater hose clamps may not have been tightened properly, allowing a heater hose to disconnect and coolant to leak into the bus, which could cause a burn injury. Daimler Truck North America will notify owners by mail and advise taking the bus to a DTNA authorized service facility to inspect and, if necessary, tighten or replace the heater hose clamps.
