2012 Kenworth T270 recalls

• Lights And Instruments#2020148April 7, 2020

  65,284 units affected

  Issue: On certain trucks, the warning light for the tractor anti-lock brake system (ABS) may not turn on if the system loses power. If this happens, the driver will not get warning that the ABS is not working properly. Note: This problem would also cause the traction control (TC) and electronic stability control (ESC) lights not to turn on. Safety Risk: If a driver is not warned that the ABS is not working properly, there could be an increased risk of a crash. Corrective Actions: PACCAR will notify owners by mail and instruct you to take your truck to a dealer to update the software for the cab control module (CECU).

  22,815 units affected

  On certain vehicles, water could migrate into wiper motor head and could lead to internal corrosion. This internal corrosion could form a conductive salt bridge which could result in a short circuit, causing the wiper system to fail. Loss of windshield wiping capability, should it occur during a rainy/snowy day, may compromise the driver's ability to see the road and its users, and a short circuit could increase the risk of fire, which could result in injury and/or damage to property. Correction: Dealers will install a shield over the wiper motor to protect it from water intrusions and prevent corrosion.

• Brakes#2012027January 27, 2012

  1,434 units affected

  On certain trucks equipped with Bendix ATR-6 Antilock Traction Relay valves, in extremely cold conditions (at or below -18 degrees Celsius), internal ATR valve leakage can occur. This could cause unintended brake application, which could overheat the affected brakes and cause a fire. Also, in certain low traction conditions, unexpected brake application can cause a loss of vehicle control and a crash. These issues could result in property damage and/or personal injury. Correction: Dealers will update the cover assembly on the ATR valves.

• Brakes#2011105March 7, 2011

  64 units affected

  On certain vehicles, the slack adjuster housings may have been manufactured incorrectly, which could allow the housings to fracture and fail. As a result, the wheel brake to which the slack adjuster is attached would no longer function, which could increase vehicle stopping distances. Should a steer axle slack adjuster fail, it could also cause the vehicle to pull to one side during braking. Either problem could result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the slack adjusters.

• ELECTRONIC STABILITY CONTROL (ESC)#20V199000April 6, 2020

  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."

  Risk: 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.

• VISIBILITY:WINDSHIELD WIPER/WASHER:MOTOR#15V271000May 8, 2015

  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.

  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.

  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.

• SERVICE BRAKES, AIR:SUPPLY:HOSES, LINES/PIPING, AND FITTINGS#12V530000October 12, 2012

  Kenworth is recalling certain model year 2012 and 2013 T270 and T370 medium duty trucks built with Eaton Ultrashift transmissions between December 7, 2011, and April 6, 2012. The air harness from the treadle valve on the affected vehicles was routed in a manner that can cause the air brake lines to be pinched between the cab and the electronic clutch actuator of the Eaton Ultrashift transmission. Significant movement between the cab and transmission can cause progressive wear and an eventual leak in the air lines.

  Risk: Air lines which leak can cause reduced brake function, which may result in a crash.

  Remedy: Kenworth will notify owners, and dealers will repair the vehicles free of charge. The safety recall began on November 30, 2012. Owners may contact Kenworth at 1-425-828-5000.

• SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE#12V026000January 30, 2012

  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.

  Risk: 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.
