Cummins Inc. (Cummins) and Cummins Westport Inc. are recalling certain Cummins Westport ISL G engines, part number G6LTAA8.9E, manufactured February 26, 2007, to April 14, 2015. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
Cummins has begun the process of notifying the affected vehicle manufacturers and vehicle owners. Dealers will secure the ends of the 90-degree elbow. In addition, the electronic control module (ECM) will be reprogrammed with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact Cummins customer service at 1-800-343-7357. Cummins number for this recall is C1627.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
