2011 Peterbilt 384 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).

• Engine#2015211May 15, 2015

  169 units affected

  On certain vehicles equipped with Cummins Westport ISL-G engines, excessive engine crankcase pressure could cause the vent tube assembly elbow to detach from the breather. This could allow engine oil to come in contact with hot surfaces, increasing the risk of fire resulting in injury and/or damage to property. Correction: Dealers will install clamps at both ends of the elbow of the breather tube assembly and reprogram the Electronic Control Module (ECM) to improve diagnostic capabilities.

• Airbag#2014198May 29, 2014

  4 units affected

  On certain vehicles, a wiring defect could cause the airbag warning lamp to fail to illuminate in the event of a fault with the side curtain airbag system. As a result, a fault could go undetected by the driver, and cause the side airbag to fail to deploy in a crash. This could increase the risk of injury. Correction: Dealers will affect repairs.

• Powertrain#2011263July 21, 2011

  23 units affected

  On certain trucks equipped with a PACCAR MX engine and Eaton Ultrashift DM or Allison automatic transmission (without auto-neutral), the Fast Idle Control (also known as high idle) may be activated by the operator while the transmission is in gear. This could override the parking brake, allowing the vehicle to move unexpectedly. Unintended vehicle movement could result in a crash causing property damage and/or personal injury. Correction: Dealers will update the engine control software.

• Engine#2011087February 25, 2011

  589 units affected

  On certain vehicles equipped with a PACCAR MX engine, the oil module centrifugal spinner filter cap may become loose, possibly allowing the cap to come off and engine oil to partially discharge from the oil module onto nearby exhaust components. The discharge of engine oil onto hot exhaust components could result in a fire causing property damage and/or personal injury. Correction: Dealers will re-torque the oil module filter cap and install a secondary retention device on the secondary centrifugal spinner filter cap.

• Engine#2010329October 4, 2010

  59 units affected

  On certain vehicles, the exhaust gas recirculation (EGR) oil seal installed on the output shaft of the valve actuator may delaminate, possibly allowing engine oil to leak from the EGR valve onto exhaust components. Engine oil leaking onto hot exhaust components, such as when the engine is under significant load, may create the possibility of a fire which can result in personal injury or property damage. Correction: Dealers will replace the EGR valve.

• 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.

• ENGINE AND ENGINE COOLING:ENGINE#15V309000May 26, 2015

  PACCAR Incorporated (PACCAR) is recalling certain model year 2010-2016 Kenworth T440, T800, and W900 trucks manufactured August 31, 2009, to April 20, 2015, and 2008-2015 Peterbilt 320, 337, 348, 365, 382, and 384 trucks manufactured July 27, 2007, to April 28, 2015, and equipped with certain Cummins Westport ISL G engines. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.

  Risk: If engine oil comes into contact with a hot surface, there is an increased risk of a fire.

  Remedy: Cummins will notify owners on behalf of PACCAR, and Cummins service centers will administer the repairs which include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ECM) with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact Kenworth customer service at 1-425-828-5000, Peterbilt customer service at 1-940-591-4000 or Cummins Inc. at 1-800-343-7357. PACCAR's number for this recall is 15KWH and 515-G.

• ELECTRICAL SYSTEM#14V283000May 29, 2014

  PACCAR Incorporated (PACCAR) is recalling certain model year 2010-2015 Peterbilt 579, 388, 384, 367, 365, 348, and 337 trucks manufactured October 30, 2009, through May 21, 2014. In the affected vehicles, if power is interrupted to the seat electronic control unit (ECU), such as when the fuse for that circuit blows, the side air bag would be disabled but there will not be a warning lamp indicator to notify the operator of the malfunction.

  Risk: Without a warning of a problem existing in the side air bag system, the driver may continue to operate the vehicle, increasing the risk of injury from the side air bag not deploying in the event of a rollover.

  Remedy: PACCAR will notify owners, and dealers will install a new electrical harness to correct them problem, free of charge. The recall began in July 2014. Owners may contact Peterbilt customer service at 1-940-591-4220. Paccar's number for this recall is 514-F.
