2009 Hyundai Sonata Q&A
2009 Hyundai Sonata Question: RADIO IN 2009 SONATA DOES NOT COME ON IN THE AM 1ST THING.
May be an internal problem in the radio, call the dealer or Hyundia North America customer service and ask if they have seen this problem before. Is your radio still covered under warranty by Hyundia? If not google Original stereo repair, phone these people that specialize in OE stereo repair see if they have seen this problem before. - patrick mannion
I just had this fixed in mine. It started happening when it got cold. They had to replace the rear window due to a short in the antenna. It was covered by the warranty. - 2009sonata
