20V199000Electrical SystemApril 6, 2020 · 460,515 units

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 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."

Consequence

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.

Defect

Paccar Incorporated (Paccar) is recalling certain model year 2012-2013 Peterbilt 579 and 587 trucks manufactured February 14, 2011, to December 5, 2012 and 2011 Kenworth T700 trucks manufactured September 21, 2010, to October 1, 2010. The affected trucks are equipped with Fontaine Ultra LT Fifth Wheel connectors, which, due to cumulative damage to the fifth wheel and its locking mechanism, have a locking mechanism that may fail to operate or to properly engage.

Consequence

If the fifth wheel and locking mechanism are sufficiently damaged, the locking mechanism may fail to operate as intended and the trailer may unexpectedly detach from the tractor, increasing the risk of a crash.

Remedy

PACCAR will notify owners, and dealers will replace the fifth wheel with an Ultra NT model fifth wheel, free of charge. The recall began on December 7, 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 15KWP (Kenworth) and 1015M (Peterbilt).

Remedy

15V132000OtherMarch 6, 2015 · 213,230 units

Defect

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)."

Consequence

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.

Remedy

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.

14V283000AirbagsMay 29, 2014 · 1,705 units

Defect

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.

Consequence

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
