What's wrong

Mack Trucks, Inc. (Mack) is recalling certain 2020-2025 Anthem, Granite, TerraPro and Pinnacle vehicles, equipped with Bendix EC80 Advanced Electronic Control Units (ECU). Electrical noise and low signal to the power line carrier may cause the ECU to incorrectly process commands or stop working.

Consequence

Safety systems that depend on the ECU (Automatic Traction Control, ABS, Electronic Stability Control, Active Cruise Control, and Collison Mitigation System) may have diminished or lost functionality, increasing the risk of a crash.

Remedy

Dealers will reprogram the ECU software, free of charge. Owner notification letters were mailed December 9, 2024. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0472.
