• Visibility · NHTSA 15V271000

  Aug 5, 2015Visibility:Windshield Wiper/Washer:Motor

  Problem

  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

  Fix

  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.

• Engine and Engine Cooling · NHTSA 15V309000

  May 26, 2015Engine and Engine Cooling:Engine

  Problem

  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.

  Fix

  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.

  Problem

  PACCAR Inc, is recalling certain model year 2014-2015 Kenworth T440, T660, T800, and W900 tractor trailers manufactured January 23, 2013, through February 4, 2014, and certain model year 2014-2015 Peterbilt 320, 365, 382, 384 tractor trailers manufactured January 21, 2013, through February 5, 2014, and equipped with certain Cummins Westport Model ISL G and ISX12 G engines.

• Seat Belts · NHTSA 14V013000

  Jan 24, 2014Seat Belts

  Problem

  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."

  Risk

  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.

  Fix

  May 12, 2013Exterior Lighting:Tail Lights

  Problem

  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.
