Motor Coach Industries (MCI) is recalling certain 2011-2012 MCI D4000, D4005, D4500 and D4505 coaches equipped with Cummins ISX 12 liter engines. The vehicles may have an incorrectly installed exhaust bellow pipe, resulting in a bend in the pipe which can cause its premature failure.

Risk: If the pipe fails and a diesel regeneration cycle occurs, the hot exhaust gases will increase the risk of a fire.

SEATS

Motor Coach Industries (MCI) is recalling certain model year 2011-2013 and 2015 J4500 coaches manufactured November 18, 2011, to July 10, 2015, 2011-2012 and 2014-2015 D4000 coaches manufactured manufactured September 24, 2010, to September 5, 2015, 2011-2013 and 2015-2016 D4005 coaches manufactured January 17, 2011, to November 23, 2015, 2012-2014 and 2016 D4000ISTV coaches manufactured July 18, 2012, to December 2, 2015, 2010-2016 D4500 coaches manufactured April 15, 2010, to December 18, 2015 and 2011-2016 D4505 coaches manufactured December 15, 2010, to December 4, 2015. The affected buses are equipped with certain Recaro Ergo-M Commercial Bus Driver Seats that have J-Brackets that may be missing welds which could allow the seat belt anchorage assembly to separate from the J-Bracket.

Risk: If the seatbelt anchorage assembly separates from the J-Bracket, the bus driver may not be properly restrained in the event of a crash increasing their risk of injury.

ENGINE AND ENGINE COOLING:ENGINE

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.

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

ENGINE AND ENGINE COOLING:ENGINE

Motor Coach Industries, Inc. (MCI) is recalling certain model year 2011-2012 D4000 motorcoaches manufactured March 2011 through July 2012 and equipped with certain Cummins Westport model ISL G. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.

Risk: The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.

ELECTRICAL SYSTEM:WIRING:FUSES AND CIRCUIT BREAKERS

Motor Coach Industries, Inc (MCI) is recalling certain model year 2009-2011 D4000 and D4500 and 2010 D4505 motor coaches equipped with LED lights interior lights powered by either a Vansco or IO multiplex system. Due to the excessive power draw of the LED lights, heat may build up at the fuse block and connector, causing the components to melt.

Risk: If this occurs, the surrounding material may be damaged and will burn, increasing the risk of a fire.

ELECTRICAL SYSTEM

Motor Coach Industries (MCI) is recalling certain model year 2000-2012 D, E, G and J series coaches manufactured January 2000 through June 2011 and equipped with Sure Power battery equalizers containing a particular epoxy sealing, aka 'potting', compound. The specific potting compound used in the subject products for insulation was found to be capable of conducting electricity after being exposed to heat.

Risk: Once electrically conductive, the material is capable of melting and burning, increasing the risk of a fire.

INTERIOR LIGHTING

MOTOR COACH INDUSTRIES, INC (MCI) IS RECALLING CERTAIN MODEL YEAR 2009-2011 D4000, D4500 AND 2010 D4505 MOTOR COACHES EQUIPPED WITH LED LIGHTS INTERIOR LIGHTS AND POWERED BY EITHER A VANSCO OR IO MULTIPLEX SYSTEM. DUE TO EXCESSIVE POWER DRAW OF THE LED LIGHTS, HEAT MAY BUILD UP AT THE FUSE BLOCK AND CONNECTOR, CAUSING COMPONENTS TO MELT.

Risk: IF THIS OCCURS, SURROUNDING MATERIAL MAY BE DAMAGED AND WILL BURN, INCREASING THE RISK OF A FIRE.

ELECTRONIC STABILITY CONTROL (ESC)

MOTOR COACH INDUSTRIES (MCI) IS RECALLING CERTAIN MODEL YEAR 2003, AND 2007-2012 E AND J MODELS ALONG WITH MODEL YEAR 2007-2012 D4000, D4005, D4500, D4505, D4000ISTV MOTOR COACHES EQUIPPED WITH MERITOR WABCO ELECTRONIC STABILITY CONTROL (ESC) MODULES, MANUFACTURED FROM OCTOBER 2002, THROUGH OCTOBER 2011. UNDER CERTAIN ROAD AND DRIVING CONDITIONS, VEHICLE BODY ROLL AND ROAD INCLINATION CHARACTERISTICS MAY ADVERSELY AFFECT THE SLIP ANGLE CALCULATION OF THE ELECTRONIC STABILITY CONTROL (ESC) SYSTEM. THIS MIGHT CAUSE THE ESC TO PERCEIVE AN OVER STEERING SITUATION AND THEREFORE APPLY THE OUTER WHEEL BRAKE ON THE FRONT AXLE UNTIL THE VEHICLE IS PERCEIVED TO BE STABLE.

Risk: IF THE DRIVER IS SLOW TO REACT DURING THIS ESC INTERVENTION, THE VEHICLE MAY DEVIATE FROM THE INTENDED LINE OF TRAVEL, INCREASING THE RISK OF A CRASH.
