⚠️ Do Not Drive advisory. NHTSA and the manufacturer advise owners of affected vehicles not to drive them until this recall is repaired.

What's wrong

Mack Trucks, Inc. (Mack) is recalling certain 2020-2022 Mack MD vehicles. The cotter pin that retains the brake pedal clevis pin may not have been properly installed, which could result in an unsecured brake pedal.

The risk

An unsecured brake pedal can cause a loss of braking ability and increase the risk of a crash.

The fix

Owners are advised to not drive their vehicles until the remedy has been performed. Dealers will inspect the cotter pin installation and repair it as necessary, free of charge. Owner notification letters were mailed on September 13, 2021. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0429.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
