I too have a noisy AM band on my 2007 Hyundai. And, the radio abruptly went almost deaf a few years ago. Now it is good only for strong locals.
The noise is caused by the car's computer creating wide band hash right on my favorite news channel, "News radio 780" making 780khz unusable. This hash starts out low, just below 780 and drifts upward as the computer warms up ending up right on top of 780. After the radio went deaf I can now hear ignition noise that varies with engine speed. Suspect a loose or corroded ground some where. I would have to pull the bottom of dashboard apart to get to the wiring. The hash could probably be eliminated with a choke and a few capacitors in the 12v line as close to radio as possible. And the deafness probably due to a bad ground or perhaps an antenna lead in issue. In the mid 1980's I owned a Chevy Celebrity with a high quality Delco digital AM/FM set. AM stopped at 1610khz, but the set had excellent sound and good sensitivity and selectivity. If I had the time I would rip out the piece of junk that I have now and put in the Delco set I saved when I junked the Celebrity. Most newer cars have low quality, poorly designed electrical systems with no filtering that interferes with the crappy AM radios.
