IC Bus Cesb Recall 17V257: Unfused heater pump circuit can cause fire risk

NHTSA campaign 17V257, reported April 18, 2017, 336 vehicles potentially affected.

What this recall means for you

The power circuit for the heater booster pump in certain school buses may be unfused, meaning it lacks the circuit protection that normally shuts off electricity during a fault. If the heater booster pump suffers an electrical failure, the lack of protection can increase the risk of a fire.

The remedy is free. Authorized dealers will relocate the circuit to a fused section of the power distribution center. Owners will be notified by mail. You can also contact Navistar customer service at 1-331-332-1590, referencing recall number 17503. Check your vehicle identification number (VIN) for open recalls to confirm whether your bus is affected.
