Plain-English summary

Mack Trucks, Inc. is recalling certain Bendix EC80 Advanced Electronic Control Units (ECU) with part numbers K190048 and K163499. The defect involves electrical noise and low signal to the power line carrier, which may cause the ECU to incorrectly process commands or stop working entirely.

This malfunction may result in diminished or lost functionality for safety systems that depend on the ECU, including Automatic Traction Control, ABS, Electronic Stability Control, Active Cruise Control, and the Collision Mitigation System. The loss of these systems increases the risk of a crash.

Dealers will reprogram the ECU software free of charge to correct the issue. Owner notification letters are expected to be mailed on December 15, 2025. Owners may contact Mack's customer service at 1-800-866-1177 for more information. Mack's number for this recall is SC0490.
