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.

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.

SERVICE BRAKES, AIR:ANTILOCK:ABS WARNING LIGHT

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.

FUEL SYSTEM, OTHER:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS

PACCAR Incorporated (PACCAR) is recalling certain 2015-2018 Kenworth K370, T680, T880 and 2017-2018 Peterbilt 567 and 579 trucks. The plastic fuel tee fittings on these trucks may leak fuel.

Risk: A fuel leak in the presence of an ignition source can increase the risk of a fire.

POWER TRAIN:DRIVELINE:DRIVESHAFT

PACCAR Incorporated (PACCAR) is recalling certain model year 2014 and 2015 Kenworth T660, T680, and T800 trucks manufactured January 29, 2013, to April 2, 2014, and 2013 Peterbilt 587 trucks manufactured on August 8, 2012. The affected trucks are built with a driveshaft that may not transmit power to the wheels due to weld failure from corrosion.

Risk: If the weld fails causing a loss of power to the rear wheels, the vehicle operator may be unable to move the vehicle, or may experience deceleration if the vehicle is in motion, increasing the risk of a vehicle crash.

POWER TRAIN:AXLE ASSEMBLY

PACCAR Incorporated (PACCAR) is recalling certain model year 2015-2016 Kenworth T680 and T880 trucks manufactured November 17, 2014, to January 5, 2015. The affected vehicles are equipped with Meritor MT-40-14X rear drive axles that may circulate an inadequate amount of lubricant to the wheel end hub assembly.

Risk: Without adequate lubrication to the wheel end hub assembly, the bearings may fail prematurely, increasing the risk of a wheel-end fire or crash.

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.

ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR

The affected trucks, equipped with PACCAR MX-13 engines and Delco-Remy 40SI alternators, have alternator charge cables that may chafe against a formed metal freon discharge line.

Risk: If the alternator cable rubs through its insulation, an electrical short may occur, increasing the risk of a fire.
