Summary

Some 2025-2026 Mustang vehicles equipped with a 5.0L or 2.3L engine and built on 15-Aug-2025 and through 01-Dec-2025 may exhibit various drivability symptoms and/or have diagnostic trouble codes (DTC) stored in the powertrain control module (PCM) related to throttle/pedal position circuits.
