    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.

    Defect, in the NHTSA record
    PACCAR Incorporated (PACCAR) is recalling certain 2012-2018 Kenworth T800 and T880 vehicles equipped with Neway ADZ tridem rear suspensions. The brake control airline may be the incorrect size, resulting in an imbalance in the service brake application timing. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air brake systems."
    Consequence, in the NHTSA record
    An incorrectly sized airline may lengthen the distance needed to stop the vehicle, increasing the risk of a crash.
    Remedy, in the NHTSA record
    Kenworth will notify owners, and dealers will modify the air brake system with updated brake piping, free of charge. The recall began on June 21, 2017. Owners may contact Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is 17KWB.

    Engine and Engine Cooling / Engine

    Defect, in the NHTSA record
    PACCAR Incorporated (PACCAR) is recalling certain model year 2010-2016 Kenworth T440, T800, and W900 trucks manufactured August 31, 2009, to April 20, 2015, and 2008-2015 Peterbilt 320, 337, 348, 365, 382, and 384 trucks manufactured July 27, 2007, to April 28, 2015, and equipped with certain Cummins Westport ISL G engines. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
    Consequence, in the NHTSA record
    If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
    Remedy, in the NHTSA record
    Cummins will notify owners on behalf of PACCAR, and Cummins service centers will administer the repairs which include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ECM) with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact Kenworth customer service at 1-425-828-5000, Peterbilt customer service at 1-940-591-4000 or Cummins Inc. at 1-800-343-7357. PACCAR's number for this recall is 15KWH and 515-G.

    Visibility / Windshield Wiper/Washer / Motor

    Defect, in the NHTSA record
    PACCAR Incorporated (PACCAR) is recalling certain model year 2011-2016 Kenworth T270, T370, T440, T470, C500, C540, C550, T660, T800, W900, and 963 trucks manufactured November 1, 2010, to April 6, 2015. In the affected trucks, water may leak into the wiper motor.
    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.

  6. 13V573000Received . 18 units.

    Service Brakes

    Defect, in the NHTSA record
    PACCAR is recalling certain model year 2007-2014 Kenworth T800 and W900 trucks manufactured March 22, 2006, through July 15, 2013 and equipped with Primaax tridem rear suspensions and a pusher and/or tag axle. The affected trucks have brake chambers that take longer to apply or release the brakes than the required time limit. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."
    Consequence, in the NHTSA record
    Brakes that take longer to apply may lengthen the distance needed to stop the truck, increasing the risk of a crash.
    Remedy, in the NHTSA record
    PACCAR will notify owners, and dealers will modify the air brake system, free of charge. The recall began on January 15, 2014. Owners may contact PACCAR at 1-425-468-7400. Kenworth's recall number is 13KWL.

  7. 12V026000Received . 15,932 units.

    Service Brakes, Air / Supply / Check Valve

    Defect, in the NHTSA record
    Paccar is recalling certain model year 2012-2013 kenworth t170, t270, t370, t440, t470, t660, t700, t800, w900, and peterbilt 320, 330, 337, 348, 365, 367, 382, 384, 386, 388, 389, and 587 vehicles, manufactured from january 31, 2011, through january 19, 2012, and equipped with bendix atr-6 antilock 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.
    Consequence, in the NHTSA record
    Unexpected continuous brake application can cause the brakes to overheat and lead to a fire. Unexpected continuous brake application can cause the driver to lose control of the vehicle, increasing the risk of a crash. Also, the brakes may be applied without illuminating the brake lights, failing to give proper warning to other drivers.
    Remedy, in the NHTSA record
    Paccar will notify owners, and provide a temporary repair until bendix develops a permanent remedy. This service will be performed free of charge. The safety recall began on february 10, 2012. Owner may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 12KWA/0112-A. Owner notification date in the NHTSA record: .

  8. 11V380000Received . 211 units.

    Electrical System / Software

    Defect, in the NHTSA record
    Paccar is recalling certain model year 2011-2012 kenworth t660, t700, and t800 vehicles manufactured from april 19, 2010, through may 13, 2011, and model year 2008, 2010, and 2011 peterbilt 365, 367, 384, 386, 387, 388 and 587 vehicles manufactured from april 20, 2010, through june 11, 2011, and equipped with paccar mx engines and eaton ultrashift dm or allison automatic transmissions (without auto-neutral). The fast idle control may be activated by the operator while the transmission is in gear.
    Consequence, in the NHTSA record
    If the fast idle control function is engaged with the transmission in gear, the vehicle could unexpectedly accelerate and override the parking brake and , creating a risk of a crash and damage to other vehicles or property and the potential for injury to nearby pedestrians.
    Remedy, in the NHTSA record
    Kenworth and peterbilt dealers will update the engine software for the affected chassis. This service will be performed free of charge. The safety recall began on august 22, 2011. Owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number E038R. Owner notification date in the NHTSA record: .

  9. 11V157000Received . 280 units.

    Service Brakes, Air / Slack Adjusters

    Defect, in the NHTSA record
    Paccar is recalling certain model year 2011-2012 kenworth t270/370, t440/t470, t800, t660, w900 and c500 vehicles manufactured between october 18, 2010, and january 28, 2011. Certain cast iron slack adjuster housings, which transmit braking force from the brake chamber push rod to the brake cam tube, may include a flow notch in the handle portion of the housing due to an error during the casting process. A flow notch in the handle portion may reduce the effective cross section structure and cause the slack adjuster housing to fracture.
    Consequence, in the NHTSA record
    If the slack adjuster housing were to fracture, the wheel brake to which the slack adjuster housing is attached would no longer function, which could increase vehicle stopping distances, and if mounted on the steer axle, could cause the vehicle to pull to one side during braking, increasing the risk of a crash.
    Remedy, in the NHTSA record
    Dealers will inspect and replace the slack adjuster housing as necessary. This service will be performed free of charge. The safety recall began on march 30, 2011. Owners may contact kenworth at 425-828-5440.

    Report filed by PACCAR INCORPORATED. Manufacturer campaign number 11KWA. Owner notification date in the NHTSA record: .

  10. 11V127000Received . 4,664 units.

    Fuel System, Other / Storage / Tank Assembly

    Defect, in the NHTSA record
    Paccar is recalling certain model year 2008-2012 kenworth t2000, t660, t700, t800, and w900, as well as model year 2009-2012 peterbilt 365, 367, 384, 386, 387, 388, 389, and 587 trucks equipped with paccar mx engines. The oil module centrifugal spinner filter cap in the paccar mx engine may become loose, possibly allowing the cap to come off and engine oil to partially discharge from the oil module onto exhaust components.
    Consequence, in the NHTSA record
    The discharge of engine oil onto exhaust components which are hot, such as when the engine is under significant load, may cause a fire.
    Remedy, in the NHTSA record
    Dealers will re-torque the oil module filter cap and install a secondary retention device on the secondary centrifugal spinner filter cap. This service will be performed free of charge. The safety recall is expected to begin during march 2011. Owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.
