Electronic stability control (ESC)

20V199000460,515 vehicles affected

The 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."
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.

Engine and engine cooling: diesel

18V55500011,429 vehicles affected

The problem
PACCAR Incorporated (PACCAR) is recalling certain 2016-2019 Kenworth C500, T660, T800, and W900 vehicles, equipped with 1.9M ISX15 engines. The engine harnesses may have been manufactured without check engine light (CEL) and stop engine light (SEL) circuits, preventing the driver from being warned of a serious engine problem.
The risk
If the driver is not warned of a serious engine problem, the engine may unexpectedly fail, increasing the risk of a crash.
The fix
PACCAR will notify owners, and dealers will inspect or test the ISX15 engine harness, and install an overlay jumper harness to supply the missing CEL and SEL circuits, free of charge. The recall began November 30, 2018. Owners may contact PACCAR customer service at 1-918-259-3258. PACCAR's number for this recall is 18KWE.

Electronic stability control (ESC)

18V36800085,626 vehicles affected

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

Steering: tie rod assembly

17V59300017,737 vehicles affected

The problem
PACCAR Incorporated (PACCAR) is recalling certain 2016 Peterbilt 220, 320, 325, 330, 337, 348, 365, 367, 382, 384, 386, 389, 389G, 567, 579 and 587 trucks and Kenworth K170, T170, T270, T370, T440, T470,T660, T680, T800, T880, and W900 trucks equipped with certain Spicer D or E series steer axles. The castellated nut on the steer axles may not be properly torqued, allowing the tie rod to loosen.
The risk
If the tie rod loosens, it may disconnect from the steering knuckle, causing a complete loss of steering and increasing the risk of a crash.
The fix
PACCAR will notify owners, and dealers will inspect the torque of the castellated nut and tie rod, tightening it as necessary. If the tie rod stud and knuckle on units cannot be sufficiently torqued, the dealer will replace the knuckle and tie rod end assembly, free of charge. The recall began on November 13, 2017.

Electrical system: module

15V597000354 vehicles affected

The problem

Exterior lighting: hazard flashing warning lights

15V45800012,551 vehicles affected

The problem
PACCAR Incorporated (PACCAR) is recalling certain model year 2011-2016 Kenworth T440, T470, T660, T680, and T880 trucks manufactured January 14, 2010, to May 22, 2015, and equipped with HID Headlamps and the option for Daytime Running Lamps (DRL). The DRLs are required to deactivate when the hazard warning lights are activated, however, the DRLs on these vehicles override the hazard flashing functionality after the brake pedal is pushed for more than two seconds. Normal hazard flashing functionality returns once the service brake is released. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, "Lamps, Reflective Devices, and Associated Equipment."
The risk
If the hazard warning lamps are overridden by the DRL, oncoming vehicles may fail to be warned, increasing the risk of a crash.
The fix
Kenworth will notify owners, and dealers will update the cab controller software, free of charge. The recall began on September 167, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. Kenworth's number for this recall is 15KWL.

Service brakes

15V457000334 vehicles affected

The problem
PACCAR Incorporated (PACCAR) is recalling certain model year 2016 Kenworth T440, T470, T660, T680, T800, T880, and W900 trucks manufactured February 16, 2015, to March 9, 2015. The affected vehicles are equipped with an SR-7 spring brake valve assembly that may have had the primary and secondary service brake applications installed in reverse. In the event of a failure in the primary or secondary circuit, the redundant circuit would not provide adequate service brake functionality. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."
The risk
A loss of braking ability would increase the risk of a crash.
The fix
Kenworth will notify owners, and dealers will inspect the vehicles and correct the air line installations as required, free of charge. The recall began on September 16, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is 15KWK.

Wheels: lugs / nuts / bolts / studs

15V27200049 vehicles affected

The problem
PACCAR Incorporated (PACCAR) is recalling certain model year 2016 Kenworth T660, T680, T800, T880, and W900 trucks manufactured February 1, 2015, to April 20, 2015. During assembly, the affected vehicles did not undergo the rear wheel mounting torque verification process, and thus the rear wheels may be loose.
The risk
If the rear wheel lug nuts are undertorqued, the wheels may separate from the vehicle, increasing the risk of a crash.
The fix
Kenworth will notify owners, and dealers will verify that the rear wheel lug nuts are correctly tightened, free of charge. The recall began on July 1, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. Kenworth's number for this recall is 15KWG.

Visibility: motor

15V271000104,807 vehicles affected

The problem
PACCAR Incorporated (PACCAR) is recalling certain model year 2011-2016 Kenworth T270, T370, T440, T470, C500, C540, C550, T660, T800, W900, and 963 trucks manufactured November 1, 2010, to April 6, 2015. In the affected trucks, water may leak into the wiper motor.
The risk
As water leaks in, the wiper may cease to function on the 'intermittent' setting, reducing the driver's visibility and increasing the risk of a crash. Additionally, the water may cause corrosion which, over time, may result in an electrical short, increasing the risk of a fire.
The fix
PACCAR is still developing and testing a remedy. The recall is expected to begin in July 2015. An interim letter was sent to owners on July 2, 2015. The recall began on September 2, 1015. Owners may contact Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is 15KWF.

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.
