While driving the vehicle, the stereo system suddenly without warning started an unbearable loud and deafening noise. I was driving on a busy highway and was able to the the next exit. I had 2 other occupants in the vehicle. We had to exit the vehicle because the noise level from the speaker was painful and caused disorientation. I turned the vehicle off but the noise continued for at least 10 minutes then stopped. Myself and the 2 other occupants still have ear pain 24 hours later.
