While driving down the road I had my volume set to a 5. Out of no where the volume gradually started to go up on it's own. When I tried to turn it down with the knob it wouldn't budge. It went all the way up to 30 on it's own so I finally had to shut it off for my whole hour long drive to work. When I got back into my car after work and turned the car on the radio turned on on it's own at the volume level of 30. I quickly turned it down, and it stayed down.
