Sign in to monitor this recall

Summary

Mack Trucks, Inc. is recalling 3 units of the 2025 Mack Anthem (AN) vehicles because the idler gear bracket fasteners may not have been tightened properly during manufacturing. This defect can allow the idler gear to detach from the engine while the vehicle is in use. If the gear detaches, it can cause severe engine damage and lead to a sudden stall, and Mack dealers will inspect and replace the turbo compound units free of charge.

Risk
