Reported: 2015-04-03 (April 3, 2015)

PACCAR Incorporated (PACCAR) is recalling certain model year 2015-2016 Kenworth T680 and T880 trucks manufactured November 17, 2014, to January 5, 2015. The affected vehicles are equipped with Meritor MT-40-14X rear drive axles that may circulate an inadequate amount of lubricant to the wheel end hub assembly.

Consequence: Without adequate lubrication to the wheel end hub assembly, the bearings may fail prematurely, increasing the risk of a wheel-end fire or crash.

Remedy: Kenworth will notify owners, and dealers will replace the defective rear drive axle and inspect the wheel ends for damage, replacing them, as needed, free of charge. The recall began May 29, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is 15KWB.

Reported: 2015-05-08 (May 8, 2015)

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.

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

Remedy: 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.

Reported: 2015-05-11 (May 11, 2015)

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.

Consequence: If the rear wheel lug nuts are undertorqued, the wheels may separate from the vehicle, increasing the risk of a crash.

Remedy: 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.

Reported: 2015-07-22 (July 22, 2015)

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."

Consequence: A loss of braking ability would increase the risk of a crash.

Remedy: 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.

Reported: 2015-07-22 (July 22, 2015)

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."

Consequence: If the hazard warning lamps are overridden by the DRL, oncoming vehicles may fail to be warned, increasing the risk of a crash.

Remedy: 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.

Reported: 2015-09-24 (September 24, 2015)

In the affected vehicles, the Engine Control Module (ECM) may short circuit, causing the engine to stall without warning.

Consequence: An engine that stalls without warning increases the risk of a crash.

Remedy: PACCAR will notify owners, and dealers will replace the defective engine control modules, free of charge. The recall began on October 22, 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 15KWM (Kenworth) and 915-L (Peterbilt).

Reported: 2015-10-09 (October 9, 2015)

Paccar (Paccar Incorporated) is recalling certain 2016 Kenworth T680, T800, and T880 trucks manufactured January 5, 2015, to January 7, 2015 and 2016 Peterbilt 367, 384, 567, and 579 trucks manufactured January 2, 2015, to January 9, 2015 and equipped with Eaton Fuller FR 10-speed manual transmissions. In the affected vehicles, when the transmission shift lever is moved from reverse to neutral, the reverse gear may stay engaged. When the transmission shift lever is moved from reverse to a forward gear position, the transmission may mechanically lock because both the reverse gear and forward gear are simultaneously engaged.

Consequence: Even though the transmission has been shifted out of reverse into neutral, the vehicle may unexpectedly move backwards, increasing the risk of a crash.

Remedy: Paccar will notify the owners, and dealers will inspect and repair the affected transmissions if necessary, free of charge. The recall began on December 4, 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 15KWM (Kenworth) and 1015N (Peterbilt).

Reported: 2017-02-15 (February 15, 2017)

PACCAR Incorporated (PACCAR) is recalling certain 2015-2018 Kenworth K370, T680, T880 and 2017-2018 Peterbilt 567 and 579 trucks. The plastic fuel tee fittings on these trucks may leak fuel.

Consequence: A fuel leak in the presence of an ignition source can increase the risk of a fire.

Remedy: Kenworth and Peterbilt will notify owners, and dealers will replace the suspect fuel tees, free of charge. The recall began on April 13, 2017.

The castellated nut on the steer axles may not be properly torqued, allowing the tie rod to loosen.

Consequence: 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.

Remedy: 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. Owners may contact Peterbilt customer service at 1-940-591-4000 or Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is P817-C.

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.

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.

PACCAR Incorporated (PACCAR) is recalling certain 2016-2021 Kenworth T680 trucks equipped with a 2.1m Cab and WABCO 6S/6M ABS brake system with drum brakes. The brake systems were manufactured with a standard rear-brake ABS modulator valve instead of a quick release valve, which may exceed the intended service-brake release timing. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

Consequence: Longer than expected service-brake release timing may lengthen vehicle stopping distance, increasing the risk of a crash.

Remedy: PACCAR will notify owners, and dealers will replace the standard rear-brake, ABS modulator valve with a quick release valve, free of charge. The recall began November 30, 2020. Owners may contact PACCAR customer service at 1-425-828-5888. PACCAR's number for this recall is 20KWD.
