Recall campaigns
Defect, as filed: 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.
Filed by PACCAR Incorporated (manufacturer campaign 20pbc AND 20KWB); components: electronic stability control (esc); service brakes, air:antilock:abs warning light.
Defect, as filed: 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.
Filed by PACCAR Incorporated (manufacturer campaign 15KWF).
Defect, as filed: 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.
Filed by PACCAR INCORPORATED (manufacturer campaign 11KWA).
Defect, as filed: Kenworth is recalling certain model year 2011 t270, t370, and t800 trucks manufactured from january 28 through march 19, 2010, equipped with dv-2 air governor containing part number g90-1070-2111111 on the t270/370 model trucks and part number g90-1070-11113111 on the t800 model trucks. The dv-2 air governor was misassembled with a blank plug instead of a breather. Without the breather installed, the air governor may not be able to detect the loss of air pressure in the air system during normal use. This condition may result in the slow activation of the emergency spring brakes.
Consequence: Although the operator is warned of low air pressure by audible and visual low air pressure warning alarms, a vehicle crash or fire is possible if these warnings are not heeded.
Remedy: Kenworth will notify owners and repair the vehicles by replacing the blank plug with a breather and inspect for proper function free of charge. The safety recall began on june 10, 2010. Owners may contact kenworth at 1-425-828-5440.
Filed by PACCAR INCORPORATED (manufacturer campaign 10KWD).
