Electronic stability control (ESC)

Summary: 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: If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.
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.
Components: Electronic stability control (ESC); Service brakes, air › Antilock › ABS warning light

Service brakes, air › Supply › Check valve

Summary: 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: 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: 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.

Service brakes, air › Slack adjusters

Summary: 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: 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: 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.
