   Service Brakes, Air / Supply / Reservoir/Tank

   Defect, in the NHTSA record

   PACCAR Incorporated (PACCAR) is recalling certain 2009-2021 Kenworth C500, 2012-2021 Kenworth T440, 2009-2015 Kenworth T660, 2015-2024 Kenworth T680, 2009-2024 Kenworth T800, 2009-2020 Kenworth T370, 2014-2023 Kenworth T880, 2011-2016 Kenworth T470, 2023 Kenworth T480, and 2009-2019 Kenworth W900 vehicles. The air tanks have an insufficient volume of air for the brake system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

   Consequence, in the NHTSA record

   Insufficient air volume can reduce braking performance and increase the risk of a crash.

   Remedy, in the NHTSA record

   Dealers will install the correct volume air tanks, free of charge. Owner notification letters were mailed August 12, 2024. Additional owner notification letters were mailed October 27, 2025. Owners may contact PACCAR customer service at 1-425-828-5888. PACCAR's number for this recall is 24KWD.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 24KWD. Owner notification date in the NHTSA record: 12 Aug 2024.

2. 20V199000Received 6 Apr 2020. 460,515 units.

   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.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 20pbc AND 20KWB. Owner notification date in the NHTSA record: 26 May 2020.

3. 15V309000Received 26 May 2015. 4,823 units.

   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.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 15KWH and 515-G. Owner notification date in the NHTSA record: 12 Jun 2015.

4. 15V271000Received 8 May 2015. 104,807 units.

   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.

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

5. 13V573000Received 18 Nov 2013. 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.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 13KWL. Owner notification date in the NHTSA record: 15 Jan 2014.

6. 11V157000Received 7 Mar 2011. 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: 30 Mar 2011.

7. 11V127000Received 23 Feb 2011. 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.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number E026R. Owner notification date in the NHTSA record: 4 Mar 2011.

8. 10V535000Received 27 Oct 2010. 417 units.

   Service Brakes, Air / Disc / Caliper

   Defect, in the NHTSA record

   Paccar is recalling certain model year kenworth t660, t700, t800 and w900 vehicles manufactured from december 22, 2008, through august 2, 2010, and equipped with ag400l air disc brakes. The air disc brake caliper could be installed on the wrong side of the drive axle potentially causing interference with the suspension bracket and the rear suspension as the outermost brake pads wear and the floating caliper moves inboard.

   Consequence, in the NHTSA record

   As this interference gets larger, this could eventually lead to reduced braking performance, increasing the risk of a crash.

   Remedy, in the NHTSA record

   Dealers will verify the correct orientation of the brake caliper and perform the necessary repair free of charge. The safety recall began on november 24, 2010. Owners may contact kenworth at 425-828-5440.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number 10KWH. Owner notification date in the NHTSA record: 24 Nov 2010.

9. 10V453000Received 1 Oct 2010. 384 units.

   Engine and Engine Cooling / Exhaust System / Emission Control / Gas Recirculation Valve (Egr Valve)

   Defect, in the NHTSA record

   Paccar is recalling certain model year kenworth and peterbilt vehicles. A manufacturing defect in the seal supplied by a component manufacturer installed on the output shaft of the exhaust gas recirculation (egr) valve actuator may cause eventual delamination of the seal. Delamination of the seal may allow engine oil to leak from the egr valve onto exhaust components.

   Consequence, in the NHTSA record

   The leaking of engine oil onto hot exhaust components, such as when the engine is under significant load, may create the possibility of a fire.

   Remedy, in the NHTSA record

   Dealers will replace the egr valve assembly on the subject vehicles equipped with the paccar mx engine. This service will be performed free of charge. The safety recall began on october 29, 2010. Owners may contact kenworth at 425-828-5440 and peterbilt at 940-591-4196.

   Report filed by PACCAR INCORPORATED. Manufacturer campaign number E008R. Owner notification date in the NHTSA record: 29 Oct 2010.

10. 10V452000Received 29 Sep 2010. 3,040 units.

    Exterior Lighting

    Defect, in the NHTSA record

    Kenworth is recalling certain model year 2011 t660, t800, w900, c500, t440, and t470 vehicles manufactured from april 1, 2009, through august 30, 2010. One of the four harness spade terminal connections to the chassis load center may become completely unseated. A completely unseated connection may result in a power loss to a portion of the vehicle's exterior lighting.

    Consequence, in the NHTSA record

    Power loss of the vehicle's exterior lighting may reduce the visibility of the vehicle to other drivers increasing the risk of a crash with the vehicle.

    Remedy, in the NHTSA record

    Dealers will inspect the harness and re-seating the female connectors on the male spade terminals. This service will be performed free of charge. The safety recall began on october 29, 2010. Owners may contact kenworth at 1-425-828-5440.
