Tens of thousands of Mack and over 100,000 International trucks are involved in a significant recall concerning Bendix electronic control units (ECUs). This action is part of Bendix’s extensive recall impacting hundreds of thousands of ECUs.
The National Highway Traffic Safety Administration (NHTSA) reports that more than 60,000 Mack trucks—from model years 2020 to 2025, including the Anthem, Granite, Pinnacle, and TerraPro—are being recalled due to issues with Bendix EC80 Advanced ECUs. Problems such as electrical interference and inadequate power line signals may lead the ECU to misinterpret commands or cease functioning altogether.
International Motors is also recalling over 105,000 trucks for similar reasons. The impacted models include:
- 2021-2025 HV
- 2021-2025 HX
- 2021-2024 LoneStar
- 2021-2025 LT
- 2021-2025 MV
- 2022 ProStar
- 2021-2025 RH
These malfunctions in the Bendix ECU could impair critical safety functions like automatic traction control, anti-lock braking systems (ABS), electronic stability control, active cruise control, and collision mitigation systems, thereby heightening crash risks.
The faulty EC80 ECUs are primarily installed in “towing vehicles.” Bendix utilizes a power line carrier network enabling communication between tractor and trailer through an electrical signal. This signal is prone to failure, particularly in trucks towing multiple trailers compared to those with a single trailer.
Mack Trucks has documented 55 warranty claims as of October 30th, where the ABS light activated, causing the system to go “offline” without affecting other safety features. Fortunately, no field reports, accidents, or injuries have been linked to the Bendix ECU malfunction so far.
Authorized dealers will offer free reprogramming of the affected Bendix ECU software. Mack truck owners will receive notification letters on December 13, while International truck owners can expect theirs on December 23.
This recall is part of a broader issue initiated on October 11, affecting over 400,000 ECUs distributed to Volvo Trucks and Navistar. Volvo has already recalled nearly 127,000 trucks featuring these ECUs.
