The defect
Mack Trucks, Inc. (Mack) is recalling certain 2025 Anthem (AN) vehicles. The idler gear bracket fasteners may have been improperly tightened, allowing the idler gear to detach from the engine.
The risk
A detached idler gear can damage the engine, resulting in a stall and increasing the risk of a crash or injury.
The remedy
Dealers will inspect and replace the turbo compound units as necessary, free of charge. Owner notification letters are expected to be mailed April 24, 2025. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0477.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 888-327-4236 (TTY 888-275-9171) or go to nhtsa.gov.
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
