New Flyer Industries Ltd. (New Flyer) is recalling certain model year 2009-2012 C35LFR, 2008-2013 C40LF, 2008-2013 C40LFR, 2009 L40LFR, 2009 C35LF, 2013-2014 XN35, 2011-2014 XN40, and 2012-2014 XN60 buses, equipped with certain Cummins Westport ISL G engines. 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 the engine oil comes into contact with hot surfaces, it can increase the risk of a vehicle fire.
Cummins will notify owners on behalf of New Flyer, and Cummins service centers will administer the repairs which include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ECM) 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 25, 2015. Owners may contact New Flyer customer service at (204) 224-6706. New Flyer's number for this recall is R15-007.
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.
