I just got my 2020 Kona EV SEL and have had at least two friends complain about an odd noise that sounds like tin cans or metal objects bouncing around in the background. I'm talking to them with my iPhone 12 over the bluetooth connection. I tried plugging the USB cable in connecting to auto play and the same sound is heard on the other end. My connection with them is fine and I don;t hear the sound. One friend recorded it for me so I could hear what it sounds like. Does anybody else have the same problem and/or know of a fix.
