2013 KENWORTH T680

SERVICE BRAKES, AIR:ANTILOCK:ABS WARNING LIGHT

PACCAR Incorporated (PACCAR) is recalling certain 2008-2019 Peterbilt 330, 335, 337, 340, 348, 365, 367, 384, 386, 387, 388, 389, 567, 579 and 587 vehicles and 2008-2020 Kenworth T170, T270, T370, T660, T680, T800, T880, and W900 vehicles equipped with NAMUX Software. In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems," and 136, "Electronic Stability Control System on Heavy Vehicles."

Risk: If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.

EXTERIOR LIGHTING

PACCAR Incorporated (PACCAR) is recalling certain 2013-2019 Kenworth T680 and T880 and Peterbilt 579 trucks, greater than 30 feet long and equipped with side extender mounted intermediate marker lamp/turn signals that do not include a reflex reflector. Since both intermediate side marker lamps and reflex reflectors are required, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: Missing reflex reflectors can reduce the vehicle's visibility to other drivers, increasing the risk of a crash.

ELECTRICAL SYSTEM:WIRING:FUSES AND CIRCUIT BREAKERS

PACCAR Incorporated (PACCAR) is recalling certain 2013-2017 Peterbilt 567 and 579 Kenworth T680 and T880 trucks equipped with optional spotlights. The spotlight circuit may not be adequately protected in the event of a short.

Risk: A short in the spotlight circuitry may increase the risk of a fire at the cab fuse block.

EXTERIOR LIGHTING:HEADLIGHTS

PACCAR Incorporated (PACCAR) is recalling certain model year 2011-2016 Kenworth T440, T470, T660, T680, and T880 trucks manufactured January 14, 2010, to May 22, 2015, and equipped with HID Headlamps and the option for Daytime Running Lamps (DRL). The DRLs are required to deactivate when the hazard warning lights are activated, however, the DRLs on these vehicles override the hazard flashing functionality after the brake pedal is pushed for more than two seconds. Normal hazard flashing functionality returns once the service brake is released. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: If the hazard warning lamps are overridden by the DRL, oncoming vehicles may fail to be warned, increasing the risk of a crash.

LATCHES/LOCKS/LINKAGES

PACCAR Inc. is recalling certain model year 2013-2014 Kenworth T680 chassis manufactured January 1, 2012, through October 14, 2013, and Peterbilt 567 and 579 chassis manufactured January 20, 2012, through October 11, 2013, and equipped with Inteva-brand door latch assemblies. In the affected vehicles, the doors may lock permanently while closed or may be opened from the outside even after they have been locked.

Risk: If the door latch assembly becomes permanently locked while closed occupants could be prevented from exiting the vehicle in the event of a crash or fire, increasing the risk of injury.

PARKING BRAKE

PACCAR Incorporated (PACCAR)is recalling certain model year 2013-2014 T660, and T680 vehicles manufactured from December 4, 2012, through September 17, 2013 and configured as a dead axle tandem with air disc brakes and spring brake delete options. The affected vehicles have the parking brake incorrectly placed on the non-driven rear axle.

Risk: If the parking brake is on the non-driven axle the vehicle could roll away when the parking brakes are set, resulting in an increased risk of a crash.

ELECTRICAL SYSTEM

PACCAR is recalling certain model year 2013-2014 Kenworth T680 and T880 trucks, manufactured from January 18, 2012, through February 1, 2013; and model year 2013-2014 Peterbilt 579 and 567 vehicles, manufactured from January 20, 2012, through January 31, 2013. The Exterior Lights Self-Test switch is intended to be used when the vehicle is parked. If the switch is pressed while the vehicle is in motion, the Exterior Lights Self-Test switch will cause all exterior lighting to be extinguished.

Risk: An unexpected loss of lighting during vehicle operation may reduce the driver's ability to see other vehicles, pedestrians, or objects, as well as reduce the truck's visibility to other drivers or pedestrians, increasing the risk of crash.

SEAT BELTS

PACCAR is recalling certain model year 2013-2014 Kenworth T680 and T880 trucks and model year 2013-2014 Peterbilt 567, 579 and 587 trucks equipped with air ride seats. The cables for anchoring the seat belt buckles of both the driver and passenger seat may fray.

These vehicles were equipped with the air suspension dump valve option. New software may cause the rear air suspension to re-inflate without warning when the operator turns the ignition key to the "off" position.

Risk: An unexpected re-inflation of the suspension could result in personal injury to a person near the rear suspension.

EQUIPMENT:OTHER:LABELS

Paccar is recalling certain model year 2013 Kenworth T680 vehicles, manufactured from January 19, 2012, through May 15, 2012. The warning label located on the front of the upper bunk may deform after installation, making the text unreadable.
