2008 PIERCE QUANTUM

ELECTRICAL SYSTEM:SOFTWARE

Pierce Manufacturing (Pierce) is recalling certain 2004-2018 Arrow XT, Dash, Enforcer, Impel, Quantum and Velocity aerial vehicles. The aerial device may unexpectedly rotate to the right when the ladder is being extended.

Risk: If the aerial device moves in an unexpected direction, the ladder may contact an object, such as a building or an electrical wire, increasing the risk of injury.

STRUCTURE

Pierce Manufacturing (Pierce) is recalling certain 2007-2017 Pierce Velocity, Impel, Arrow-XT, Quantum, and Enforcer emergency response vehicles equipped with 75ft aerial devices with a 21 inch or 28 inch limited retraction bracket. The bracket on the aerial device may detach from the aerial and fall to the ground.

Risk: If the bracket falls, it could strike a person below.

POWER TRAIN:AXLE ASSEMBLY:AXLE SHAFT

Pierce Manufacturing (Pierce) is recalling certain 1999-2013 Arrow XT, Dash, Enforcer, Quantum and Velocity fire trucks equipped with the electric All-steer rear steering option. The affected vehicles have rear steer axle shafts that were not properly heat treated.

Risk: Axle shafts that are not properly heat treated may break and potentially disable the vehicle, increasing the risk of a crash.

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL

Pierce Manufacturing (Pierce) is recalling certain model year 2008-2011 Quantum fire apparatus manufactured February 21, 2008, to April 25, 2011. The mechanical springs used to return the accelerator pedal to idle after the driver lifts their foot off the pedal may break.

Risk: If the springs break, the pedal may not return to idle once the driver lifts their foot off the pedal. This unintended acceleration increases the risk of a crash.

ELECTRONIC STABILITY CONTROL (ESC)

PIERCE MANUFACTURING (PIERCE) IS RECALLING CERTAIN MODEL YEAR 2007-2011 ARROW XTAND VELOCITY, MODEL YEAR 2008-2011 CUSTOM CONTENDER, IMPEL, QUANTUM AND MODEL YEAR 2009-2011 SABER EMERGENCY TRUCKS, EQUIPPED WITH MERITOR WABCO ELECTRONIC STABILITY CONTROL (ESC) MODULES, MANUFACTURED FROM DECEMBER 19, 2007, THROUGH OCTOBER 7, 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.

ENGINE AND ENGINE COOLING

PIERCE IS RECALLING CERTAIN MODEL YEAR 2006 THROUGH 2010 ARROW XT, DASH, LANCE, QUANTUM, AND VELOCITY EMERGENCY VEHICLES MANUFACTURED FROM DECEMBER 20, 2006, THROUGH FEBRUARY 1, 2010, EQUIPPED WITH DETROIT DIESEL SERIES 60 ENGINES. THE ENGINE MAY SHUT DOWN UNEXPECTEDLY WHEN A DIESEL PARTICULATE FILTER OVER TEMPERATURE CONDITION IS DETECTED.

Risk: UNEXPECTED EMERGENCY VEHICLE ENGINE SHUTDOWN UNDER CERTAIN CONDITIONS COULD HAMPER RESCUE OPERATIONS AND PLACE THE PUBLIC AT RISK.
