Stereo/Infotainment system loud bang followed by increasingly loud static through the speakers. Occured 20 or so seconds after starting the truck and driving down the road. Happened around 2800 miles and has only happened once. Initial bang was startling and the static noise was distracting which could have caused an accident. Volume button non functional. Stopping and shutting vehicle completely off and on momentarily did nothing. After letting the truck sit off and locked for 5min+ the sound finally stopped and everything returned to normal. There was a distinct burning smell left in the truck for the rest of the day. Ears were left ringing for a couple hours after. Possible ear damage from this. Luckily there wasn't anyone else in the vehicle that could have suffered from ear damage. Dealer is aware of the issue but hasn't looked at the truck as duplicating the issue is near impossible. No warning lamps or anything visually different from normal. I have video of the static noises.
