What this recall covers

NHTSA's campaign record, quoted as published

The defect

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."

The risk

An engine that does not return to idle quickly enough can cause a loss of vehicle control, increasing the risk of a crash.

The remedy

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.

Notes

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.

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.
