It happened several times already. My F150 Tremor randomly has extremely loud electrical sound POP through the speakers followed by the loud static, no matter I listen to radio or connect to android studio. It's super dangerous to hear this while driving.

I was in the process of turning onto a two lane road when all of a sudden I heard an incredibly loud noise, much like speakers blowing out that seemed to be progressively getting louder. I remained calm. I tried to turn down volume on the speakers and it would not stop the loud sound. I put the truck in park and turned off the truck. That did not work so I turned it on and off again and the noise stopped. The volume was not working at all after this happened. I was completely confused because I didn't understand what happened or why. The sound was excruciating and fortunately when this happened I was able to safely put the truck in park and turn it on and off. If I were in traffic or driving that would probably not be possible. I can see this easily causing an accident if someone is in traffic and panics. I immediately called the dealer after this happened. They said they had not heard of this happening before. I presented them with this article I found in the WSJ - "Ford Confronts Strange, Ear-Piercing Static in F-150 Trucks, Drivers have complained to federal regulators of abnormal noise coming from the vehicle-??s speakers", By Ryan Felton & Nora Eckert. This article states the noise was recorded so loud as to damage hearing. There are many complaints about this happening online as well and something should be done. This is without question a safety issue and there should be a mandatory recall.
