On more than one occasion, the speakers have emitted an ear piercing startling noise while driving. The first time it happened, i was driving and I could not get the noise to stop despite turning off the radio. My ears ached for days. It had been only a couple days since I purchase the vehicle. I took it to Ford-??s service department. It stayed there for a few days only to be told they cannot find any issue with the car or software The second and 3rd time it happened, the radio was not on but my phone was connected through the USB port. The duration of the screeching was shorter but still disturbing enough to leave me shaking. Both the volume on the car radio and the volume on my phone were set to a very low setting. Screeching noise emitted was loudly deafening and a safety hazard.

While my granddaughter was driving this vehicle there was a sudden loud boom and the radio went to max volume, causing an excruciating decibel level of noise and static. Fortunately she was on a low volume road and was able to immediately stop the vehicle in the road (In shock of course) and she then tried to turn the radio off to no avail! She exited the vehicle, called her dad who was nearby and he showed up and turned the vehicle off. This ear piercing noise would not stop until several moments after the vehicle was turned off. This noise was so sudden, shocking and deafening that had she been on a high volume roadway she could have easily been been involved in a serious accident while attempting to turn off the radio (which didn't work) or get to a safe place to exit the vehicle. There was/is also the real possibility of permanent hearing loss!

This is the first episode of this event. I have been driving the vehicle for 17,000 miles. It was raining outside. When I pressed the button to start the ignition a horrifically loud screeching noise that terminated in what sounded like an explosion seemed to come from the passenger side if the vehicle. It last only a few seconds but it created a piercing sensation in my ears and left my ear was ringing for 10 minutes. I had to check my right ear for bleeding. Two hours later, my ear is still warm internally and aching. After the explosion, none of the audio worked on the vehicle. I tried the radio, the phone audio, the maps, and a voice phone call. I turned the car off and then on again. Still no sound. I drove for 30 minutes, waited an hour, then restarted the car and the audio returned. Prior to this, I have had daily issues with the sound mildly increasing and decreasing Independent of the road noise. I am now very fearful that this noise will happen again. If it had happened while I was driving the pain was intense enough to make me have an accident. I am concerned for hearing damage. Since it just happened and it is after hours, I have not taken it to the dealer yet. There were no warning lights or alarms before this happened,
