Ear piercing sound coming from what appears to be the stereo speaker system. It was so loud it felt like it blew out my ear drums by the time I got it turned off. Days later my ears are still ringing with intermittent headaches. I have scheduled a warranty service with the local ford dealership. There was no warning and started as soon as I started the car. No one has inspected the vehicle. This took place on 6/14/2025.
