The defect
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.
The risk
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.
