Electronic stability control (ESC)
- What is wrong
- 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.
- 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.

Seat belts
- What is wrong
- 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."
- Risk
- 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.
- 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.

An internal defect in the ignition switch causes the starter to engage when a key is partially inserted, before the key is turned.
- Risk
- 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.
- Remedy
- PACCAR will notify owners, and dealers will replace affected ignition switches, free of charge. The recall began on June 14, 2013.

Defect investigations
Intermittent Loss of Power Steering Assist
On May 1, 2020, the Office of Defects Investigation (ODI) opened PE20006 to investigate complaints of intermittent loss of power steering assist in Daimler Truck North America (DTNA), Volvo Trucks of North America (Volvo) and PACCAR vehicles equipped with a ZF/TRW (TRW) THP60 steering gear. The investigation focused on 2010-2020 DTNA Freightliner Cascadia, M2 and WST; Volvo VN, VAH and VHD and PACCAR 337, 365, 389, 567, 579 model vehicles.Field reports and interviews with fleet drivers allege that high power steering fluid temperatures could result in internal seal and bearing failures causing pressure fluctuation, affecting left and right-hand turns. The inability of the driver to steer the vehicle as intended can increase the risk of a crash and injury. ODI analyzed data provided by TRW, DTNA, Volvo, and PACCAR in response to individual information request letters.ODI found that most failures occurred within the first two years and/or 50,000 miles of service.  The claim rate decreased with time and miles in service and remained less than 0.5%. ODI normalized data from each of the manufacturers and determined that there was not a substantial difference in the failures.Additionally, TRW improved a seal in the steering gear in December 2015.Trucks built on or after 2016 (as 2017 and newer model years) show a decreasing trend of failures. In view of the overall low failure rate, the nature of early-life failure, and failure rate trending downward for model years 2017 and newer, this Preliminary Evaluation (PE) is closed. The closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist.The Agency reserves the right to take additional action if warranted by future circumstances.
