2008 Peterbilt 579 Problems, Complaints & Recalls

Problem: 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.

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.

Problem: PACCAR Incorporated (PACCAR) is recalling certain model year 2006-2016 Peterbilt 587, 579, 567, 389, 388, 387, 385, 382, 379, 378, 367, 365 and 357 trucks manufactured July 25, 2005, to February 26, 2016. The affected vehicles may be equipped with Tire and Rim Certification Labels that list a tire pressure below the actual correct amount. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 120, "Tire selection and rims and motor home/recreation vehicle trailer load carrying capacity information for motor vehicles with a GVWR of more than 4,536 kilograms (10,000 pounds)."

Risk: If the tires are underinflated due to the incorrect inflation pressure listed on the label, the truck may not be able to carry the maximum gross vehicle weight rating (GVWR) load listed without experiencing tire failure which would increase the risk of a crash.

Fix: Peterbilt will notify owners and mail them a corrected Tire and Rim certification label, free of charge. The recall began on June 19, 2015. Owners may contact Peterbilt customer service at 1-940-591-4000. PACCAR's number for this recall is 215-D.
