I was playing music from the Spotify app when the volume suddenly ramped up to max for no reason. I scrolled down the volume on the left scroll button, but the volume ramped back up again. This went back and forth a few times, before I stopped the car and reset the entire system. I had the car for 1.5 year, and this was the first time this happened. I've heard of bluetooth issues, but this wasn't it because I wasn't playing the music through my phone. Has anyone encounter this problem?
