Issued by Navistar, Inc. · Reported Apr 17, 2020 · 23,299 vehicles affected

What's wrong

Navistar, Inc. (Navistar) is recalling certain 2017-2021 IC CE School Buses equipped with Cummins B6.7 diesel engines with fuel module option number FS90301 or FS90453. The electric fuel heater within the fuel module may overheat and cause plastic in the fuel heater to melt and potentially catch fire. It may also lead to engine stalling.

Consequence

A fire increases the risk of injury. An engine stall can increase the risk of a crash.

Remedy

Cummins will notify the affected Navistar customers and dealers will disable the fuel heater by either installing a plug in place of the heater or otherwise rendering the fuel heater non-operable and remove the fuse supplying electrical power to the fuel heater and install a cover over the wire harness connector, free of charge. The recall began May 28, 2020. Owners may contact Cummins customer service at 1-800-286-6467.
