Summary

Some 2025-2027 Expedition/Navigator vehicles may exhibit an intermittent electronic static/buzzing/screeching/humming noise from the front audio speakers that changes with engine RPM. This may be due to a software concern with the active noise cancellation system. Replacement of audio system components will not resolve this condition. Advise customers that engineering is currently investigating and developing a software solution that is expected by the end of Q1 2027. If experienced, customers can temporarily clear the abnormal noise condition by stopping the vehicle in a safe location, placing the transmission in park, then pressing the audio volume control/power button 5 times until the vehicle center screen begins to reboot. The condition should also be temporarily resolved after parking the vehicle with the ignition off, doors locked, and keys moved more than 15 feet away from the vehicle allowing all systems to go to sleep for at least 15 minutes.
