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.

The positive battery jumper terminal cable may be too long, allowing it to chafe against the left front suspension spring and result in an electrical short circuit.

Consequence

An electrical short circuit can increase the risk of a fire.

Remedy

PACCAR will notify owners, and dealers will inspect the battery jumper terminal cables, and replace them as necessary, free of charge. The recall began April 30, 2020. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's number for this recall is 20PBA.

18V816000LightingNovember 16, 2018 · 1,619 units

Defect

PACCAR Incorporated (PACCAR) is recalling certain 2013-2019 Kenworth T680 and T880 and Peterbilt 579 trucks, greater than 30 feet long and equipped with side extender mounted intermediate marker lamp/turn signals that do not include a reflex reflector. Since both intermediate side marker lamps and reflex reflectors are required, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Consequence

Missing reflex reflectors can reduce the vehicle's visibility to other drivers, increasing the risk of a crash.

Remedy

PACCAR will notify owners and dealers will install reflex reflective tape, free of charge. The recall began January 15, 2019. Owners may contact PACCAR customer service at 1-918-259-3258. PACCAR's number for this recall is 18KWF, and 18PBC.

Defect

PACCAR Incorporated (PACCAR) is recalling certain 2013-2017 Peterbilt 567 and 579 Kenworth T680 and T880 trucks equipped with optional spotlights. The spotlight circuit may not be adequately protected in the event of a short.

Consequence

A short in the spotlight circuitry may increase the risk of a fire at the cab fuse block.

Remedy

PACCAR will notify owners, and dealers will change the polyfuse switch in the spotlight circuit to a standard fuse, free of charge. The recall began on September 19, 2017. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's number for this recall is 17KWC and 717-B.

15V456000Electrical SystemJuly 22, 2015 · 288 units

Defect

The affected trucks, equipped with extended-body Leece Neville alternators, have alternator charge cables that may chafe against a formed metal freon discharge line.

Consequence

If the alternator cable rubs through its insulation, an electrical short may occur, increasing the risk of a fire.

Remedy

Peterbilt will notify owners, and dealers will reroute the alternator charge cable away from the metal freon line and install a plastic insulator on the cable end, free of charge. The recall began on September 23, 2015. Owners may contact Peterbilt customer service at 1-940-591-4000. Peterbilt's number for this recall is 715-K.

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.

14V810000BrakesDecember 29, 2014 · 1,623 units

Defect

PACCAR Incorporated (PACCAR) is recalling certain model year 2015 Peterbilt 367, 389, 567, 579, and 587 trucks manufactured from May 23, 2014, to February 13, 2015, and 2015 Kenworth T270, T370, T440, T470, T660, T680, T800, T880, and W900 trucks manufactured from May 23, 2014, to February 13, 2015, equipped with certain air brake actuators. The affected vehicles may experience brake drag due to an improperly seated diaphragm in the brake chamber.

Consequence

Brake drag may result in a wheel end fire.

Remedy

Kenworth and Peterbilt will notify owners, and dealers will inspect and replace the brake chamber, as necessary, free of charge. An interim notice was mailed to owners March 3, 2015. The recall began on May 14, 2015. Owners may contact PACCAR customer service at 1-425-828-5000 (Kenworth), or 1-940-591-4000 (Peterbilt).

14V283000AirbagsMay 29, 2014 · 1,705 units

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.

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
