Driver not Warned when ABS Offline/FMVSS 121, 136

NHTSA #20V199000 · Electronic Stability Control (ESC) · NHTSA notice

Reported April 6, 2020 · PACCAR Incorporated

Potentially affected: 460,515 vehicles

Repair completion: 33.98% (latest rate the manufacturer reported to NHTSA; dataset updated November 3, 2026)

Manufacturer campaign 20pbc AND 20KWB · Owners notified May 26, 2020

Defect description

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."

Safety consequence

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

Manufacturer 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.

Reported June 10, 2015 · Rush Truck Centers of Texas, LP

Potentially affected: 37 vehicles

Owners notified July 16, 2015 · Vehicles built March 26, 2010 – March 9, 2015 (per NHTSA)

Defect description

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 210, "Seat Belt Assembly Anchorages."

Safety consequence

If the seat belt anchor pulls away, the seat occupant may not be properly secured in the event of a crash, increasing the risk of occupant injury.

Vent Tube May Detach from Engine Breather

NHTSA #15V309000 · Engine and Engine Cooling — Engine · NHTSA notice

Reported May 26, 2015 · PACCAR Incorporated

Potentially affected: 4,823 vehicles

Manufacturer campaign 15KWH and 515-G · Owners notified June 12, 2015 · Vehicles built July 27, 2007 – April 28, 2015 (per NHTSA)

Defect description

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 to come into contact with hot surfaces.

Safety consequence

If engine oil comes into contact with a hot surface, there is an increased risk of a fire.

Manufacturer remedy

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 1-940-591-4000 or Cummins Inc. at 1-800-343-7357. PACCAR's number for this recall is 15KWH and 515-G.

Lack of Air Bag Fault Telltale Lamp

NHTSA #14V283000 · Electrical System · NHTSA notice

Reported May 29, 2014 · PACCAR Incorporated

Potentially affected: 1,705 vehicles

Repair completion: 22.35% (latest rate the manufacturer reported to NHTSA; dataset updated November 3, 2026)

Manufacturer campaign 514-F · Owners notified August 4, 2014 · Vehicles built October 30, 2009 – May 21, 2014 (per NHTSA)

Defect description

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.

Safety 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.

Manufacturer remedy

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.

Seat Belt may be Difficult to Unlatch/FMVSS 209

NHTSA #14V013000 · Seat Belts · NHTSA notice

Reported January 24, 2014 · PACCAR Incorporated

Potentially affected: 10,414 vehicles

Repair completion: 58.86% (latest rate the manufacturer reported to NHTSA; dataset updated November 3, 2026)

Manufacturer campaign 14KWC/PB114-B · Owners notified March 31, 2014 · Vehicles built August 7, 2013 – November 3, 2013 (per NHTSA)

Defect description

PACCAR Incorporated (PACCAR) is recalling certain model year 2014 Kenworth T660, T680, T700,T800, T880, W900, T440, T470, T370, T270, T170, C500, and C550 chassis manufactured between August 7, 2013, and October 31, 2013, and Peterbilt 320, 325, 330, 337, 348, 365, 367, 382, 384, 386, 388, 389, and 587 chassis manufactured between August 7, 2013, and November 3, 2013, and equipped with IMMI-brand L9 seat belt buckles. When the button is pressed to release the seat belt, the latch plate can become partially engaged with the buckle, making the seat belt difficult to unlatch. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 209, "Seat Belt Assemblies."

Safety consequence

If the latch plate remains partially engaged after the button is pressed, egress from the vehicle could be hindered which would increase the risk of injury in the event of an emergency.

Manufacturer remedy

PACCAR will notify owners, and dealers will inspect and replace the seat belt buckles, as necessary, free of charge. The recall began on March 31, 2014. Owners may contact PACCAR at 1-425-468-7400. Kenworth's number for this campaign is 14KWC. Peterbilt's number for this campaign is 114-B.

Manufacturer campaign 13KWF, 0513-E · Owners notified June 14, 2013 · Vehicles built May 1, 2013 – May 17, 2013 (per NHTSA)

Defect description

PACCAR is recalling certain model year 2014 Kenworth T170, T270, T370, T470, T660, T680, T800, T880, and W900 trucks manufactured May 6, 2013, through May 17, 2013; and model year 2014 Peterbilt 330, 337, 348, 365, 367, 382, 384, 386, 388, 389, 389K, 567, 579 and 587 trucks manufactured May 1, 2013 through May 17, 2013. An internal defect in the ignition switch causes the starter to engage when a key is partially inserted, before the key is turned.

Safety consequence

Unintended engine startup could cause injury to a person working in the engine compartment. Vehicles with standard transmissions may experience unexpected movement, which may result in personal injury or a crash.

Manufacturer remedy

PACCAR will notify owners, and dealers will replace affected ignition switches, free of charge. The recall began on June 14, 2013. Owners may contact Kenworth at 1-425-828-5000 or Peterbilt at 1-940-591-4000. Kenworth's recall campaign number is 13KWF. Peterbilt's recall campaign number is 0513-E.
