Motor Coach Industries Recalls D4000 and D4500 Coaches Due to Fire Risk
Motor Coach Industries (MCI) is recalling certain model year 2011-2012 D4000 and 2014-2015 D4500 coaches.
Excessive engine crankcase pressures in the affected coaches 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 a hot surface, it can increase the risk of a vehicle fire.
Motor Coach Industries will notify owners of the recalled D4000 and D4500 coaches, 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.
For further information on this recall, call MCI customer service toll-free at 1-800-241-2947 or Cummins Inc. at 1-800-343-7357.
MCI's reference number for this recall is SB 423.
