What's wrong

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

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