Cummins Recalls Engine Heaters after 7 Navistar Truck Fires

April 30, 2019 by Alan Adler, @AlanAdler

Cummins Inc. is recalling medium-duty diesel engines used in Navistar International Corp. trucks, buses and emergency vehicles because of seven fires related to overheating of the electric fuel heater.

Internal electrical arcing within the fuel heater may cause plastic in the fuel heater to melt and catch fire, Cummins said. It also may cause an engine stall.

An undetected and uncontained fire could lead to injury, the National Highway Traffic Safety Administration said. A stalled engine could increase the possibility of a crash.

Cummins knows of no injuries or accidents from the fires, all of which were contained in the vehicles’ fuel heaters.

Cummins began looking into warranty claims in July 2018. By February this year, 123 claims had been filed, and 64 fuel heaters had been returned for analysis.

All the engine heaters were sold to Navistar, which issued recalls 19V-216 and 19V-217 covering 43,264 vehicles. About 1 in 10 vehicles with the B6.7 engine equipped with the fuel module that included an electric fuel heater are suspected to have the issue.

Affected vehicles are certain 2017-2020 International DuraStar and WorkStar; 2018-2020 IC Bus CECB, International HV and MV; 2018-2019 IC Bus 1300 FBC and HCCB; and 2019-2020 IC Bus TCCB.

The NHTSA number for the recall is 19E-020.

Cummins will remove the fuel heater fuse and replace any fuel heater found with damage or a fuel leak with a temporary cavity plug. Cummins will notify Navistar customers when a permanent fix is determined. Cummins began leaving out the fuel heaters in production in February.
