Cummins Inc. and Cummins Westport Inc. are recalling 25,013 natural gas engines that may have a problem that can cause fires in the exhaust pipe.
The recall involves certain Cummins Westport Model ISL G engines manufactured Sept. 12, 2007, through Feb. 2, 2014, and Cummins Westport Model ISX12 G engines manufactured Feb. 19, 2013, through Feb. 2, 2014.
No injuries have been reported, but Cummins Westport has received two reports of flames coming from vehicle exhaust pipes.
The problem is described as condensation in the intake manifold, which may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor. Consequently, improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
Cummins Inc. and Cummins Westport Inc. began notifying manufacturers on Feb. 14. Heavy truck and bus builders are being told that dealers will upload a new ECM calibration, free of charge. The manufacturers have not yet provided a schedule for notifying vehicle owners. For more information, owners can call 800-343-7357.
Cummins’ number for this recall is C1462 (for ISL G engines) or C1461 (for ISX12 G) engines.
