MCI D4000 and D4500 Motorcoaches Recalled for Engine Fire Risk

Motor Coach Industries is recalling 2011-2012 D4000 and 2014-2015 D4500 motorcoaches because a vent tube defect may allow engine oil to contact hot surfaces, increasing fire risk.

What this means for you

Our assessment, not the agency’s: severity 3/5 (High).

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: The recall addresses a risk-of-harm product (vehicle fire) where injury has not yet been reported, which aligns with the 'High' severity criteria in the rubric.

Plain-English summary

Motor Coach Industries (MCI) is recalling certain model year 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. The recall involves a defect in the engine and engine cooling system where excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather.

This detachment may allow engine oil to come into contact with hot surfaces. If engine oil contacts a hot surface, it can increase the risk of a vehicle fire. The source text does not report any specific incidents of fire or injury associated with this defect.

MCI will notify owners, and Cummins service centers will administer the repairs free of charge. The repairs include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ECM) with software that adjusts engine output under misfire conditions to limit crankcase pressures. 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.
