NHTSA campaign 20V220, reported April 17, 2020, 23,299 vehicles potentially affected.

What this recall means for you

Certain IC school buses with Cummins B6.7 diesel engines may have an electric fuel heater in the fuel module that can overheat. The plastic in the heater can melt and potentially catch fire, and the engine may stall.

A fire increases the risk of injury, and an engine stall can increase the risk of a crash. Owners should take this recall seriously and have the work done as soon as possible. The repair is free at an authorized dealer: the fuel heater will be disabled by installing a plug in its place or otherwise making it non-operable, the fuse supplying power to the heater will be removed, and a cover will be installed over the wire harness connector. Cummins customer service can be reached at 1-800-286-6467. Check your vehicle's VIN for open recalls to confirm whether your bus is affected.
