Cummins Westport Recalls 25,000 Nat-Gas Engines
Cummins Inc. and Cummins Westport Inc. are recalling 25,013 natural gas-fueled engines due to a weather sensor problem that could cause flames in the exhaust pipes.
The recall covers 16,746 ISL G 8.9-liter engines that had their engine control modules recalibrated between September 2007 and January 2013, as well as 5,713 ISL G engines produced in 2013 and 2014. It also includes 2,554 ISX12 G 12-liter engines produced in 2013 and 2014, Cummins and Cummins Westport told the National Highway Traffic Safety Administration, which publicized the recalls Feb. 28.
Cummins and Cummins Westport told NHTSA that in cold weather, the temperature and pressure sensor may ice over, causing the engine to take in too much fuel. This could overheat the exhaust and cause fires in the exhaust pipe, as was reported in two cases.
The companies notified owners, who can take their vehicles to service shops and have the engines recalibrated.
Cummins Westport, a joint venture between Cummins and Westport Innovations, learned of the defect Jan. 29 and notified NHTSA Feb. 12. The defect has not caused any injuries, it said.
