2015 MCI D4500; 2014 MCI D4500; 2011 MCI D4000; 2012 MCI D4000
Check against the official notice below — it lists the full affected range.
Motor Coach Industries is recalling certain 2011-2012 D4000 motorcoaches manufactured between November 12, 2011, and July 11, 2012, and 2014-2015 D4500 motorcoaches manufactured between July 4, 2014, and April 30, 2015. These vehicles may have excessive engine crankcase pressures that can cause a 90-degree elbow on the vent tube assembly to detach from the crankcase ventilation breather, potentially allowing engine oil to contact hot surfaces and increasing the risk of vehicle fire.
MCI will notify owners, and Cummins service centers will perform repairs at no charge. The repairs include securing the ends of the 90-degree elbow and reprogramming the electronic control module with software to adjust engine output under misfire conditions and limit crankcase pressures. The recall began on June 18, 2015. Affected owners should contact MCI customer service at 1-800-241-2947 or Cummins Inc. at 1-800-343-7357, and can reference MCI recall number SB 423.
