08- Electrical#2020276
111 units affected
Issue: On certain buses, a build-up of corrosion on the alternator connection could cause it to malfunction. If this happens, the alternator voltage output may increase. As a result, the control module may switch off the engine and cause a vehicle shutdown. Safety Risk: A sudden loss of engine power and vehicle shutdown could increase the risk of a crash. Corrective Actions: Motor Coach Industries (MCI) will notify owners by mail and instruct you to take your bus to an authorized repair facility to update the software in the Vehicle Multiplexing Module (VMM). MCI also recommends periodically inspecting, cleaning and re-applying corrosion inhibitor to the alternator.
- Engine#2018256
138 units affected
On certain motor coaches, the exhaust bellows pipe may fail prematurely and cause a leak. An exhaust leak during a regeneration event could allow the leakage of hot gases and could increase the risk of fire, causing property damage and/or personal injury. Correction: Dealers will install a new exhaust pipe assembly.
- Engine#2017280
35 units affected
On certain vehicles, the bellows pipe (a component of the exhaust system) may have been installed incorrectly and could fail. As a result, combustion from a Diesel Particulate Filter regeneration event could exit the failed bellows pipe instead of being completely contained within the exhaust system. If this occurs, the hot combustion gases could cause a fire which may result in property damage and/or personal injury. Correction: Authorized MCI service facilities will inspect and, if necessary, replace the bellows pipe. Note: This is an expansion of recall 2013-121.
- Electrical#2014236
85 units affected
Certain coaches previously repaired as part of recall 2012173 may require additional modifications. The power draw from the LED interior lights may exceed the design limits of the fuse block terminal and power splice connector installed as part of the previous recall. As a result, these components could overheat, potentially resulting in a vehicle fire causing property damage and/or personal injury. Correction: MCI authorized facilities will install a revised fuse holder for the LED interior lights.
- Engine#2013121
18 units affected
On certain vehicles, the bellows pipe (a component of the exhaust system) may have been installed incorrectly and could fail. As a result, combustion from a Diesel Particulate Filter regeneration event could exit the failed bellows pipe instead of being completely contained within the exhaust system. If this occurs, the hot combustion gases could cause a fire which may result in property damage and/or personal injury. Correction: Authorized MCI service facilities will inspect and, if necessary, replace the bellows pipe.
- Electrical#2012173
85 units affected
On certain coaches, the power draw from the LED interior lights may exceed the design limits of the electrical circuit. This could allow certain components to overheat, which could result in a vehicle fire causing property damage and/or personal injury. Correction: MCI authorized facilities will modify the electrical circuit for the LED interior lights.
- Other#2011377
245 units affected
On certain vehicles, specific operating conditions (such as tight, successive, highly banked curves in opposite directions), could trigger unintended Electronic Stability Control (ESC) system intervention. As a result, the ESC may unnecessarily apply one of the front brakes in order to correct the perceived oversteer condition. This may cause the vehicle to deviate from the intended path, thereby increasing the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the ESC module.
- Wheels#2010153
22 units affected
On certain coaches, the front and/or tag axle assemblies may have been installed with improper torque applied to the hub/rotor/wheel adapter bolts. Reduced bolt torque could lead to vibration loosening of the bolt, and could result in a wheel off condition. This could result in a crash causing property damage, personal injury or death. Correction: Dealers will verify the torque of the affected hub/rotor/wheel adapter plate bolts and replace the bolts as necessary.
