Service Brakes, Hydraulic › Antilock/Traction Control/Electronic Limited Slip › Control Unit/Module (24V915000, 2024-12-09)
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2021-2025 Peterbilt and Kenworth vehicles, equipped with Bendix EC80 Advanced Electronic Control Units (ECU). Please see the recall report for a complete list of models. Electrical noise and low signal to the power line carrier may cause the ECU to incorrectly process commands or stop functioning.
Risk: Safety systems that depend on the ECU (Automatic Traction Control, ABS, Electronic Stability Control, Active Cruise Control, and Collison Mitigation System) may not function properly or at all, increasing the risk of a crash.
Free fix: Dealers will reprogram the ECU software, free of charge. Owner notification letters were mailed February 3, 2025. Owners may contact Kenworth's customer service at 1-425-828-5888 and Peterbilt's customer service at 1-940-591-4220. PACCAR's numbers for this recall are 24KWL and 24PBL.
Seat Belts (23V717000, 2023-10-26)
Problem: PACCAR Incorporated (PACCAR) is recalling certain 2020 Kenworth T660, 2018-2024 Kenworth T800 and W900 vehicles. An additional spacer may have been added to the joint that connects the seat to the seat belt tether and buckle, causing an unsecured connection.
Risk: An unsecured seat belt connection may not properly restrain an occupant during a crash, increasing their risk of injury.
Free fix: Dealers will inspect and remove the additional spacer and replace the bolt, as necessary, free of charge. Owner letters were mailed March 20, 2024. Owners may contact PACCAR's customer service at 1-425-828-5888. PACCAR's number for this recall is 23KWK.

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.

The capscrews that attach the flywheel to the crankshaft may have been improperly torqued, allowing the flywheel to detach.
Risk: A detached flywheel can cause loss of drive power, increasing the risk of a crash. Additionally, driveline pieces may be ejected from the engine compartment, increasing the risk of injury.
Free fix: PACCAR will notify owners, and dealers will properly torque the capscrews and the engine will also be inspected for damage and, if necessary, repaired, free of charge.
