- Problem
- Mack Trucks, Inc. (Mack) is recalling certain 2023-2024 GR, AN, LR, and Terrapro vehicles. The engine may not return to idle within 2 seconds if the accelerator pedal position sensor becomes disconnected.

- Risk
- An engine that does not return to idle quickly enough can cause a loss of vehicle control, increasing the risk of a crash.
- Fix
- Mack will replace the throttle pedal and update the vehicle software, free of charge. Owner letters were mailed February 27, 2024. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0455.
