2011 MCI D4505

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

Motor Coach Industries (MCI) is recalling certain 2011-2016 D4500, D4505, D4000, D4005, and D4000 ISTV motor coaches equipped with ISX engines. Due to vibrations, the exhaust bellow pipes develop a hole.

Risk: If the pipe develops a hole, during a regeneration cycle, hot exhaust gases may leak out, increasing the risk of a fire.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

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.

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.

ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR

MOTOR COACH INDUSTRIES (MCI) IS RECALLING CERTAIN MODEL YEAR 2010-2011 D4505 MOTOR COACHES MANUFACTURED FROM MAY 1, 2010, THROUGH SEPTEMBER 30, 2011. THESE VEHICLES WERE EQUIPPED WITH PENNTEX ALTERNATORS THAT, AS INSTALLED, MAY COLLECT MOISTURE AT THE POWER STUD. THIS MOISTURE MAY RESULT IN CORROSION BUILDUP AT AND AROUND THE POWER STUD BASE.

Risk: THIS CORROSION MAY CREATE A SHORT CIRCUIT BETWEEN THE POWER STUD AND THE ALTERNATOR BODY, WHICH IN TURN COULD RESULT IN BURNING OF THE POWER STUD OR THE POWER CABLE END. THIS COULD INCREASE THE RISK OF A FIRE. ADDITIONALLY, THE VEHICLE BATTERY COULD DISCHARGE WHICH COULD CAUSE THE VEHICLE TO STALL.

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.
