Defect description

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."

Safety risk

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

Manufacturer remedy

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 description

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."

Safety risk

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

Manufacturer remedy

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.

Defect description

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.

Safety 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.

Manufacturer remedy

PACCAR will notify owners, and dealers will replace the defective driveshafts, free of charge. The recall began on July 15, 2015. Owners may contact Kenworth customer service at 1-425-828-5000, or Peterbilt customer service at 1-940-591-4000. PACCAR's number for this recall is 15KWJ and 515-H.

Defect description

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.

Safety risk

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.

Manufacturer remedy

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.

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.

Safety risk

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

Manufacturer remedy

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.

Defect description

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.

Safety risk

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.

Manufacturer remedy

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).

The affected vehicles have the parking brake incorrectly placed on the non-driven rear axle.

Safety risk

Defect description

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."

Safety risk

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.

Manufacturer remedy

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.

Defect description

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."

Safety risk

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

Manufacturer remedy

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.
