2007 NOVA BUS NOVA LFS

ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES

Nova Bus (Nova) is recalling certain model year 2007-2009 LFS transit buses manufactured January 1, 2007, to December 31, 2009. A power feed cable in the battery compartment may have been incorrectly routed and clipped. As a result, the battery cable may prematurely wear and short to ground.

Risk: A battery cable that shorts to ground increases the risk of a fire.

SERVICE BRAKES, AIR:ANTILOCK

Nova Bus (Nova) is recalling certain model year 2007 LFS transit buses manufactured January 1, 2007, to December 31, 2007. Two wires in the antilock brake system (ABS) connector may be reversed, and the ABS may be disabled.

Risk: Without a functioning antilock brake system, there is an increased risk of a crash.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

Nova Bus (Nova) is recalling certain model year 2007 LFS transit buses manufactured January 1, 2007, to December 31, 2007. In the affected vehicles, the band clamp on the flex pipe between the turbocharger and the diesel particulate filter may be incorrectly located allowing the exhaust pipe to leak hot exhaust gases onto nearby components.

Risk: If the components are exposed to hot exhaust gases, there is an increased risk of a fire.

ELECTRICAL SYSTEM

Nova Bus (Nova) is recalling certain model year 2006-2007 LFS transit buses manufactured January 1, 2006, to December 31, 2007. In the affected vehicles, the rear exit door controls may not function properly.

Risk: If the rear exit door does not open and close as expected, there is an increased risk of injury to bus occupants.

SERVICE BRAKES, AIR:ANTILOCK:ABS WARNING LIGHT

Nova Bus is recalling certain model year 2004 and 2006-2013 LFS transit buses. 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."

Risk: 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.

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:WHEEL SPEED SENSOR/TONE RING

NOVA BUS IS RECALLING CERTAIN MODEL YEAR 2007-2010 TRANSIT BUSES EQUIPPED WITH ATC (AUTOMATIC TRACTION CONTROL) SYSTEM AND V-BEA MULTIPLEXING SYSTEM MANUFACTURED FROM APRIL 2, 2007 THROUGH JUNE 30, 2010. THE ATC SYSTEM MAY INADVERTENTLY ACTIVATE WHENEVER THE PARKING BRAKE OR THE BRAKE INTERLOCK IS APPLIED, SINCE THE VEHICLE'S MULTIPLEX PROGRAM DID NOT CORRECTLY SEND THE PARKING BRAKE OR INTERLOCK SIGNAL TO THE ATC SYSTEM. THE ATC SYSTEM COULD MISINTERPRET THIS SITUATION AS WHEEL SPIN, SUBSEQUENTLY APPLYING AND RELEASING THE APPLIED BRAKES. THE VEHICLE COULD THEN MOVE UNEXPECTEDLY.

Risk: THE VEHICLE MAY MOVE INADVERTENTLY EVEN WHEN THE PARKING BRAKE IS APPLIED INCREASING THE RISK OF A CRASH.
