Defect

Nova Bus (Nova) is recalling certain model year 2009-2010 LFS transit buses manufactured January 1, 2009, to December 31, 2010 with ZFAV132 rear axles. The affected vehicles may have been produced with rear axle half shafts that received an inadequate surface treatment which may result in axle shaft failure.

Defect

Due to a programming error in the vehicle control unit, the ABS malfunction light may not illuminate if the ABS control unit loses power. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 121, "Air Brake Systems."

Consequence

If the ABS malfunction light does not illuminate if the ABS control unit loses power, the driver would not be aware that the ABS is not functional and that the brakes may unexpectedly lock up under certain conditions when the brakes are applied, increasing the risk of crash.

Remedy

Nova Bus will notify owners, and dealers will update the software for the instrument cluster, free of charge. The recall is expected to begin in late August 2014. Owners may contact Nova Bus customer service at 1-450-472-6410. Nova Bus' number for this recall is CR3200.

Defect

Nova Bus is recalling certain model year 2010-2014 LFS transit buses manufactured June 2010 to June 2014. In the affected vehicles, the terminal on the postive alternator cable may fracture causing the cable to arc to other components.

Consequence

Arcing of the alternator cable may result in an engine compartment fire.

Remedy

Nova Bus will notify owners, and dealers will inspect the terminal and replace it if it is damaged, free of charge. The recall began August 29, 2014. Owners may contact Nova Bus customer service at 1-450-472-6410. Nova Bus' number for this recall is CR3201.

Defect

Nova Bus is recalling certain 2009-2012 model year LFS and LFS HEV transit buses equipped with Sure Power DC-DC converters 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.

Consequence

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

Remedy

Nova Bus will notify owners and dealers will inspect and replace the converters, as necessary, free of charge. The recall is expected to begin in January 2014. Owners may contact Nova Bus at 1-450-472-6410.

Defect

Nova Bus is recalling certain model year 2010 LFS transit buses manufactured June 10, 2010, through November 11, 2010; and equipped with flush mounted windows and Ricon 3-Minute Urban Transit Bus egress window sets. The composition of the material used to cast the handles is incorrect resulting in embrittlement of the handle and a reduction in material strength. The handle(s) on the emergency egress passenger windows may break before the window latch is released.

Consequence

In the event the egress window fails during an emergency situation, passengers may be trapped in the bus placing them at risk of injury.

Remedy

Nova Bus will notify owners, and dealers will replace the egress handles free of charge. Ricon will supply the replacement handles. The recall began on December 10, 2012. Owners may contact Nova Bus at 1-877-999-8808.

NOVA BUS IS RECALLING CERTAIN MODEL YEAR 2010 LFS BUSES MANUFACTURED FROM SEPTEMBER 1, 2010, THROUGH DECEMBER 31, 2010, EQUIPPED WITH A CUMMINS ISB, ISX, ISC OR ISL DIESEL ENGINE. THE V-BAND CLAMP ASSEMBLY, PART NUMBERS Q187684, Q187685, AND Q187686, USED TO CONNECT THE INLET AND OUTLET CONE SECTIONS TO THE DIESEL OXIDATION CATALYST (DOC)/DIESEL PARTICULATE FILTER (DPF) INCLUDE A T-BOLT WHICH CAN FRACTURE AND FAIL WHEN SUBJECTED TO STRESS OR LOAD. A FRACTURE OR FAILURE OF THE T-BOLT MAY CAUSE THE CLAMP TO LOOSEN AND THE INLET OR OUTLET SECTIONS ATTACHED TO THE DOC/DPF HOUSING TO DISCONNECT.

Consequence

IF THE INLET OR OUTLET SECTIONS DISCONNECT, HOT EXHAUST GASES CAN VENT PRIOR TO EXITING THE TAILPIPE, CREATING THE RISK OF COMBUSTION AND A FIRE. IF BOTH CLAMPS FAIL, THERE IS A RISK IN SOME APPLICATIONS THAT THE DOC/DPF HOUSING MAY DETACH COMPLETELY, CREATING A ROAD HAZARD.
