Mack recall: Vehicle speed control
What is wrong
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. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 124, "Accelerator Control Systems."
What could happen
An engine that does not return to idle quickly enough can cause a loss of vehicle control, increasing the risk of a crash.
The 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.
