I bought a new Ioniq Blue Hybrid Hatchback a week ago today. Last night, having driven it about 10 miles, the radio broadcast was replaced with a happy-sounding chiming song (maybe 30-40 seconds long), and instead of showing my radio station, the radio display showed a code. I think it was either 1 000 0000 or 0 000 0000. Can anyone tell what's going on and what I should do about it?
