2011 VOLVO VHD

EXTERIOR LIGHTING

Volvo Trucks North America (Volvo) is recalling certain 2004-2019 Volvo VHD trucks equipped with snow plow lamp preparation kits. The snow plow headlights can be turned on without other exterior lights, and high beam indicator will not work when the snow plow high beams are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: The driver may operate the vehicle with the snow plow headlights on but the marker and tail lamps off, reducing the vehicle's visibility and increasing the risk of a crash.

SUSPENSION:FRONT:CONTROL ARM:UPPER BALL JOINT

Volvo Trucks North America (Volvo) is recalling certain model year 2009-2016 VHD trucks manufactured from April 7, 2008, through December 9, 2015, equipped with USK non-greasable drag links. The ball joint seals may be compromised, which can allow water and other contaminants to enter the ball joints.

Risk: If water and contaminants enter the ball joint, corrosion can occur and lead to accelerated wear, which over time can result in failure of the ball joint, possibly resulting in complete loss of steering, increasing the risk of a crash.

POWER TRAIN:CLUTCH ASSEMBLY

Volvo Trucks North America (Volvo) is recalling certain model year 2007-2014 VAH, VHD, VNL, VNM, and VT models. The affected vehicles were built without a redundant clutch disengagement switch. Without a redundant switch, a loss of signal from the brake air pressure switch can prevent the clutch from automatically disengaging when the brake is applied.

Risk: Without a signal to disengage the clutch when the brakes are applied, the distance required to stop the truck may lengthen, increasing the risk of a crash.

VISIBILITY/WIPER

Volvo Trucks North America (Volvo) is recalling certain model year 2011-2012 VAH, VHD, VNL, and VNM trucks manufactured February 1, 2010, through September 30, 2010 and June 1, 2011, through November 30, 2011. The windshield wiper motor may fail.

Risk: Inoperable wipers may result in poor driver visibility, increasing the risk of a crash.

PARKING BRAKE:CONVENTIONAL:AIR

Volvo Trucks North America (Volvo) is recalling certain model year 2011-2013 VHD and VNL vehicles manufactured December 13, 2010, through July 17, 2012. These vehicles are equipped with an MGM Type 24 J-series piston parking brake chamber. The brake chambers may leak pressure allowing the parking brake to drag when it is supposed to be released. Brake dragging could lead to overheated brake components.

Risk: Overheated brake components could result in a fire.

SEAT BELTS

Volvo is recalling certain model year 2002-2013 VHD and VN trucks, manufactured from August 4, 2000, through June 22, 2012, and equipped with bench passenger seats. The seat belt d-ring weld may not be sufficient enough to meet the seat belt pull test. Therefore, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 210, "Seat Belt Assembly Anchorages."

Risk: In the event of a crash, an insufficient seat belt weld may prevent the seat belt from properly restraining the occupant. This increases the risk of injury to the seat occupant.

SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE

VOLVO IS RECALLING CERTAIN MODEL YEAR 2011-2012 VHD AND MODEL YEAR 2011-2013 VNL AND VNM VEHICLES, MANUFACTURED FROM DECEMBER 2, 2010, THROUGH JANUARY 18, 2012, AND EQUIPPED WITH BENDIX ATR-6 TRACTION RELAY VALVES. IN EXTREMELY COLD CONDITIONS, THESE BENDIX RELAY VALVES MAY POTENTIALLY DEVELOP INTERNAL LEAKAGE. INTERNAL LEAKAGE CAN LEAD TO AIR PRESSURE BEING DELIVERED TO AFFECTED PRIMARY OR SECONDARY BRAKE CAUSING CONTINUOUS BRAKE APPLICATION.

Risk: INADVERTENT BRAKE APPLICATION CAN CAUSE THE BRAKES TO OVERHEAT AND LEAD TO A FIRE. INADVERTENT BRAKE APPLICATION CAN CAUSE THE WHEELS TO LOCK-UP LEADING THE DRIVER TO LOSE CONTROL OF THE VEHICLE, INCREASING THE RISK OF A CRASH.

SERVICE BRAKES, AIR:SLACK ADJUSTERS

VOLVO TRUCKS IS RECALLING CERTAIN MODEL YEAR 2011-2012 VHD, VNL, AND MODEL YEAR 2012 VNM TRUCKS MANUFACTURED FROM OCTOBER 15, 2010, THROUGH JANUARY 31, 2011, AND EQUIPPED WITH GUNITE AUTOMATIC SLACK ADJUSTERS. DUE TO AN INCOMPLETE "KNITTING" OF THE IRON AT THE TIME OF CASTING, INADEQUATE STRUCTURAL INTEGRITY OF THE SLACK ADJUSTER HOUSING CAN OCCUR, WHICH COULD CAUSE THE HOUSING TO BREAK AT THE HANDLE UNDER NORMAL OPERATING LOADS.

Risk: SLACK ADJUSTERS WITH THIS FLOW NOTCH COULD CRACK UNDER NORMAL BRAKING CONDITIONS CAUSING LOSS OF BRAKING WHICH COULD RESULT IN A VEHICLE CRASH.
