Defect

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

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

Remedy

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.

Defect

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

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

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.

Defect

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

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

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

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

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

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.
