   Service Brakes, Air / Antilock / ABS Warning Light

   Defect, in the NHTSA record

   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."

   Consequence, in the NHTSA record

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

   Remedy, in the NHTSA record

   PACCAR will notify owners, and dealers will update the NAMUX software within the cab control module, free of charge. PACCAR issued owners an interim notification on June 4, 2020. The recall began May 26, 2020. Owners may contact Kenworth customer service at 1-425-828-5888 or Peterbilt customer service at 1-940-591-4220. PACCAR's number for this recall is 20pbc AND 20KWB.

   Electrical System / Wiring

   Defect, in the NHTSA record

   PACCAR Incorporated (PACCAR) is recalling certain 2016-2019 Kenworth C500, T660, T800, and W900 vehicles, equipped with 1.9M ISX15 engines. The engine harnesses may have been manufactured without check engine light (CEL) and stop engine light (SEL) circuits, preventing the driver from being warned of a serious engine problem.

   Consequence, in the NHTSA record

   If the driver is not warned of a serious engine problem, the engine may unexpectedly fail, increasing the risk of a crash.

   Remedy, in the NHTSA record

The affected vehicles are equipped with an SR-7 spring brake valve assembly that may have had the primary and secondary service brake applications installed in reverse. In the event of a failure in the primary or secondary circuit, the redundant circuit would not provide adequate service brake functionality. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."

   Consequence, in the NHTSA record

   A loss of braking ability would increase the risk of a crash.

   Remedy, in the NHTSA record

   Report filed by PACCAR Incorporated. Manufacturer campaign number 15KWK. Owner notification date in the NHTSA record: 16 Sep 2015.

7. 15V458000Received 22 Jul 2015. 12,551 units.

   Exterior Lighting / Hazard Flashing Warning Lights

   Defect, in the NHTSA record

   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."

   Consequence, in the NHTSA record

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

   Remedy, in the NHTSA record

   Kenworth will notify owners, and dealers will update the cab controller software, free of charge. The recall began on September 167, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. Kenworth's number for this recall is 15KWL.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 15KWL. Owner notification date in the NHTSA record: 16 Sep 2015.

During assembly, the affected vehicles did not undergo the rear wheel mounting torque verification process, and thus the rear wheels may be loose.

   Consequence, in the NHTSA record

   If the rear wheel lug nuts are undertorqued, the wheels may separate from the vehicle, increasing the risk of a crash.

   Remedy, in the NHTSA record

   Kenworth will notify owners, and dealers will verify that the rear wheel lug nuts are correctly tightened, free of charge. The recall began on July 1, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. Kenworth's number for this recall is 15KWG.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 15KWG. Owner notification date in the NHTSA record: 1 Jul 2015.

   Consequence, in the NHTSA record

   As water leaks in, the wiper may cease to function on the 'intermittent' setting, reducing the driver's visibility and increasing the risk of a crash. Additionally, the water may cause corrosion which, over time, may result in an electrical short, increasing the risk of a fire.

   Remedy, in the NHTSA record

   PACCAR is still developing and testing a remedy. The recall is expected to begin in July 2015. An interim letter was sent to owners on July 2, 2015. The recall began on September 2, 1015. Owners may contact Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is 15KWF.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 15KWF. Owner notification date in the NHTSA record: 2 Sep 2015.

    Electrical System / Alternator/Generator/Regulator

    Defect, in the NHTSA record

    PACCAR Incorporated (PACCAR) is recalling certain model year 2014-2016 Kenworth T660, T680, T880 trucks manufactured February 18, 2013, to April 10, 2015, and 2011-2016 Peterbilt 386, 389, 567, 579, and 587 trucks manufactured December 13, 2010, to April 20, 2015. 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.

    Consequence, in the NHTSA record

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

    Remedy, in the NHTSA record

    PACCAR will notify owners, and dealers will reroute the alternator charge cable away from the metal freon line, free of charge. PACCAR issued an interim notification to owners on July 10, 2015. The recall began on September 16, 2015. Owners may contact Kenworth customer service at 1-425-828-5000 or Peterbilt customer service at 1-940-591-4000. PACCAR's numbers for this recall are 15KWE and 515-F.
