The work brake (winch brake) may unintentionally disengage the service brakes during winching operations, causing the vehicle to roll.

Service brakes, air:antilock:abs warning light; electronic stability control (esc)
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."
Risk: If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.
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.

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

An internal component in the clutch assembly may fail, possibly resulting in unintended vehicle movement.

Exterior lighting
Problem: 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."
Risk: Missing reflex reflectors can reduce the vehicle's visibility to other drivers, increasing the risk of a crash.
Fix: 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.
Engine and engine cooling:engine:diesel
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2017-2019 Kenworth C500, T600, T660, T680, T800, T880 and W900 trucks, as well as Peterbilt 367, 386, 389, 567, 579 and 587 trucks, equipped with Cummins ISX15 or X15 diesel engines. In certain driving conditions, such as on a long down-hill grade, the fuel line may burst if the fuel pump cooling circuit screen becomes restricted.
Risk: If the fuel line bursts, fuel may leak onto the road resulting in a roadway hazard for other motorists. The engine may also stall without warning, resulting in the vehicle's inability to restart, increasing the risk of a crash.
Fix: Cummins will notify owners, and dealers will replace the suspect fuel pump cooling circuit screen, free of charge. The recall began November 21, 2018. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's number for this recall is 18E081.
