Engine maker Cummins Inc. and its joint venture Cummins Westport Inc. are recalling 25,013 engines because cold weather could cause a sensor to fail, resulting in an exhaust fire.
No injuries have been reported but Cummins Westport has received two reports of flames coming from vehicle exhaust pipes.
The engines can be found in a variety of commercial vehicles including school and transit buses as well as fire trucks. Among the companies to which Cummins shipped the engines is school bus manufacturer Blue Bird Corp.
The recall affects Cummins Westport Model ISL G engines made between Sept. 12, 2007 through Feb. 2, 2014 and Cummins Westport Model ISX12 G engines made from Feb. 19, 2013 through Feb. 2, 2014.
The National Highway Traffic Safety Administration said Friday that condensation in the tubes that distribute air coming into the engine may freeze during cold weather. That ice could interfere with the proper operation of the pressure sensor, potentially increasing exhaust temperatures or causing flames from the exhaust pipe, which could burn a person or cause a fire.
