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.
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.
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.

Risk. Insufficient air volume can reduce braking performance and increase the risk of a crash.

Service Brakes
Filed Mar 15, 2022CA
While driving the factory floor mat can slide under the rear of the brake pedal while it is being applied. Once pedal is released it will still hold brake pressure causing brakes to remain engaged while still allowing vehicle to move down the road in turn causing brakes to heat up and either lockup/ catch fire or once cooled become inoperable. We have heat marks on exterior of front drums and pads were glazed over.
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
