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.

Service Brakes, Air › Disc › Chamber (21V328000, 2021-05-10)

Problem: PACCAR Incorporated (PACCAR) is recalling certain 2021 Peterbilt 348 and 579 vehicles. The spring brake chamber may have been assembled with incorrect springs that were out of specification, which may cause the pressure plate to shift.

Risk: The pressure plate may tear the diaphragm, causing a loss of air pressure and increasing the risk of a crash.

Free fix: Dealers will replace brake chambers, free of charge. Owner notification letters were mailed on July 9, 2021. Owners may contact PACCAR (Peterbilt) customer service at 1-940-591-4220. PACCAR's number for this recall is 21PBE.
