2010 Peterbilt 337 problems, complaints & recalls

Defect: 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

Risk: If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.

Fix: 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.

Defect: PACCAR Incorporated (PACCAR) is recalling certain model year 2009-2010 Peterbilt 340, 2010, 2012, and 2015-2016 Peterbilt 337, 2010 Peterbilt 335, 2011-2016 Peterbilt 348, 2009 and 2011-2016 Peterbilt 365, 2009 and 2012-2013 Peterbilt 386, 2009-2015 Peterbilt 388, 2015-2016 Peterbilt 389, and 2015 Peterbilt 567 auto hauler vehicles. The affected trucks are equipped with Michelin 295/60R22.5 XZA-2 front tires that have a speed rating less than the vehicle is governed to.

Risk: Higher vehicle speeds and other factors such as tire load and road temperatures may result in premature tire failure, increasing the risk of a crash.

Fix: Peterbilt will notify owners, and dealers will reprogram the engine's vehicle speed parameters to limit the maximum vehicle speed to the tire speed rating, free of charge. The recall began on January 4, 2016. Owners may contact Peterbilt customer service at 1-940-591-4000. PACCAR's number for this recall is 1115P.

Defect: 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

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

Defect: 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.

Fix: 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.
