What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Plain-English summary

Mack Trucks, Inc. is recalling certain 2024-2026 Mack MD Electric vehicles. The recall addresses a defect in the vehicle speed control system, specifically the throttle position sensor. When Controller Area Network (CAN) communications are interrupted, the throttle signal from the electro mobility control unit may retain the last known throttle setting. Consequently, the engine may not return to idle as intended, causing the vehicles to fail to comply with Federal Motor Vehicle Safety Standard number 124, "Accelerator Control Systems."

An engine that does not return to idle quickly enough can cause a loss of vehicle control, which increases the risk of a crash. The source text does not report any specific injuries, fatalities, or property damage associated with this defect.

Dealers will update the control unit software to correct the issue free of charge. Owner notification letters were mailed on August 14, 2025. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0481.
