- The problem

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.

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

- The problem
- PACCAR Incorporated (PACCAR) is recalling certain model year 2014-2016 Kenworth T660, T680, T880 trucks manufactured February 18, 2013, to April 10, 2015, and 2011-2016 Peterbilt 386, 389, 567, 579, and 587 trucks manufactured December 13, 2010, to April 20, 2015. The affected trucks, equipped with PACCAR MX-13 engines and Delco-Remy 40SI alternators, have alternator charge cables that may chafe against a formed metal freon discharge line.
- The risk
- If the alternator cable rubs through its insulation, an electrical short may occur, increasing the risk of a fire.
- The fix
- PACCAR will notify owners, and dealers will reroute the alternator charge cable away from the metal freon line, free of charge. PACCAR issued an interim notification to owners on July 10, 2015. The recall began on September 16, 2015. Owners may contact Kenworth customer service at 1-425-828-5000 or Peterbilt customer service at 1-940-591-4000. PACCAR's numbers for this recall are 15KWE and 515-F.
- The 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)."
- The 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.
- The 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.
- The problem
- 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.
- The 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.
- The 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.
