Defect: 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.
Consequence: 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.
Remedy: 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.

The right-hand gear shifter stalk connectors may have been improperly crimped, resulting in a loss of communication.
Consequence: A loss of communication between the gear shifter and the transmission may result in the vehicle becoming disabled after coming to a stop, increasing the risk of a crash.
Remedy: Dealers will inspect and replace the gear shifter assembly as necessary, free of charge. Owner letters were mailed December 15, 2025, then phased after that.

The timing of the trailer brake release may be delayed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
Consequence: A delay in the trailer brake release can create instability to the trailer and increase the risk of a crash.
Remedy: Dealers will replace the fittings and hoses in the affected valves, free of charge. Owner letters were mailed January 15, 2024.

When the brake pedal is fully applied and then released rapidly, the pedal plunger that connects the brake pedal to the brake valve may become disconnected, causing the service brakes to fail.
Consequence: Service brake failure can increase the risk of a crash.
Remedy: Dealers will add a pedal restraint bracket, free of charge. Owner notification letters were mailed April 7, 2023. Owners may contact Kenworth's customer service at 1-425-828-588 and Peterbilt's customer service at 1-940-591-4220. PACCAR's numbers for this recall are 23KWB and 23PBB.
