Summary

Motor Coach Industries "MCI" is recalling certain model year 2011-2012 D4000 motorcoaches manufactured November 12, 2011, to July 11, 2012, and 2014-2015 D4500 motorcoaches manufactured July 4, 2014, to April 30, 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.

Consequence

If the engine oil comes into contact with a hot surface, it can increase the risk of a vehicle fire.

Remedy

MCI will notify owners, 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 18, 2015. Owners may contact MCI customer service at 1-800-241-2947 or Cummins Inc. at 1-800-343-7357. MCI's number for this recall is SB 423.
