2020–2025 Mack Anthem (an), Mack Granite (gr), Mack Pinnacle (pi/pn) +more: Electrical System recall
NHTSA campaign 24V792000 · 59K units potentially affected · filed Oct 23, 2024
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.
Why it matters
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.
The fix
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.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153) or go to nhtsa.gov.
