   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. 14V086000Received 18 Feb 2014. 2,019 units.

   Engine and Engine Cooling / Engine

   Defect, in the NHTSA record

   PACCAR Inc, is recalling certain model year 2014-2015 Kenworth T440, T660, T800, and W900 tractor trailers manufactured January 23, 2013, through February 4, 2014, and certain model year 2014-2015 Peterbilt 320, 365, 382, 384 tractor trailers manufactured January 21, 2013, through February 5, 2014, and equipped with certain Cummins Westport Model ISL G and ISX12 G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.

   Consequence, in the NHTSA record

   The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.

   Remedy, in the NHTSA record

   PACCAR will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall began on April 12, 2014. Customers may contact PACCAR at 1-425-468-7400. Paccar's recall numbers associated with this campaign are 14KWG (Kenworth), and 214-C (Peterbilt).

   Report filed by PACCAR Incorporated. Manufacturer campaign number 14KWG/214-C. Owner notification date in the NHTSA record: 12 Apr 2014.

6. 14V013000Received 24 Jan 2014. 10,414 units.

   Seat Belts

   Defect, in the NHTSA record

   PACCAR Incorporated (PACCAR) is recalling certain model year 2014 Kenworth T660, T680, T700,T800, T880, W900, T440, T470, T370, T270, T170, C500, and C550 chassis manufactured between August 7, 2013, and October 31, 2013, and Peterbilt 320, 325, 330, 337, 348, 365, 367, 382, 384, 386, 388, 389, and 587 chassis manufactured between August 7, 2013, and November 3, 2013, and equipped with IMMI-brand L9 seat belt buckles. When the button is pressed to release the seat belt, the latch plate can become partially engaged with the buckle, making the seat belt difficult to unlatch. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 209, "Seat Belt Assemblies."

   Consequence, in the NHTSA record

   If the latch plate remains partially engaged after the button is pressed, egress from the vehicle could be hindered which would increase the risk of injury in the event of an emergency.

   Remedy, in the NHTSA record

   PACCAR will notify owners, and dealers will inspect and replace the seat belt buckles, as necessary, free of charge. The recall began on March 31, 2014. Owners may contact PACCAR at 1-425-468-7400. Kenworth's number for this campaign is 14KWC. Peterbilt's number for this campaign is 114-B.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 14KWC/PB114-B. Owner notification date in the NHTSA record: 31 Mar 2014.

7. 13V612000Received 5 Dec 2013. 5,087 units.

   Exterior Lighting / Tail Lights

   Defect, in the NHTSA record

   PACCAR Incorporated (Paccar) is recalling certain model year 2014 Kenworth T170, T270, T370, T440, T470, T660, T680, T700, T800, T880, C500 and W900 trucks manufactured July 1, 2013 through September 17, 2013. In the affected vehicles, the plastic housing of the Stop/Tail/Turn (STT) lamp can shrink and allow the light bulb to fall out of the mounted retention ring. As such, the Stop/Tail/Turn light would not be illuminated, and the vehicles do not conform to Federal Motor Vehicle Safety Standard (FMVSS) No. 108 "Lamps, Reflective Devices, and Associated Equipment."

   Consequence, in the NHTSA record

   If the stop/tail/turn light is not illuminated, the driver's intentions would not be communicated, which increases the risk of a crash.

   Remedy, in the NHTSA record

   Kenworth will notify owners, and dealers will replace the defective STT lamps with new lamps. The recall began on February 4, 2014. Customers may contact Paccar at 1-425-468-7400. Kenworth's number for this recall is 13KWM.

   Report filed by PACCAR Incorporated. Manufacturer campaign number 13KWN. Owner notification date in the NHTSA record: 4 Feb 2014.

8. 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.

9. 13V222000Received 28 May 2013. 1,773 units.

   Electrical System / Ignition / Switch

   Defect, in the NHTSA record

   PACCAR is recalling certain model year 2014 Kenworth T170, T270, T370, T470, T660, T680, T800, T880, and W900 trucks manufactured May 6, 2013, through May 17, 2013; and model year 2014 Peterbilt 330, 337, 348, 365, 367, 382, 384, 386, 388, 389, 389K, 567, 579 and 587 trucks manufactured May 1, 2013 through May 17, 2013. An internal defect in the ignition switch causes the starter to engage when a key is partially inserted, before the key is turned.

   Consequence, in the NHTSA record

   Unintended engine startup could cause injury to a person working in the engine compartment. Vehicles with standard transmissions may experience unexpected movement, which may result in personal injury or a crash.

   Remedy, in the NHTSA record

   PACCAR will notify owners, and dealers will replace affected ignition switches, free of charge. The recall began on June 14, 2013. Owners may contact Kenworth at 1-425-828-5000 or Peterbilt at 1-940-591-4000. Kenworth's recall campaign number is 13KWF. Peterbilt's recall campaign number is 0513-E.
