Recalls, owner-reported complaints, investigations and safety data

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
0
Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

SERVICE BRAKES, AIR:SUPPLY:RESERVOIR/TANK

Feb 23, 2024
936 units potentially affected
The defect: PACCAR Incorporated (PACCAR) is recalling certain 2009-2021 Kenworth C500, 2012-2021 Kenworth T440, 2009-2015 Kenworth T660, 2015-2024 Kenworth T680, 2009-2024 Kenworth T800, 2009-2020 Kenworth T370, 2014-2023 Kenworth T880, 2011-2016 Kenworth T470, 2023 Kenworth T480, and 2009-2019 Kenworth W900 vehicles. The air tanks have an insufficient volume of air for the brake system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
The risk: Insufficient air volume can reduce braking performance and increase the risk of a crash.
The remedy: Dealers will install the correct volume air tanks, free of charge. Owner notification letters were mailed August 12, 2024. Additional owner notification letters were mailed October 27, 2025. Owners may contact PACCAR customer service at 1-425-828-5888. PACCAR's number for this recall is 24KWD.

EXTERIOR LIGHTING:HAZARD FLASHING WARNING LIGHTS; EXTERIOR LIGHTING:HEADLIGHTS

Jul 22, 2015
12,551 units potentially affected
The defect: 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 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.

ENGINE AND ENGINE COOLING:ENGINE

May 26, 2015
4,823 units potentially affected
The defect: 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.
The risk: If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
The 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.
