My 2011 kia soul radio comes on when no one is in the car. Why is this happening

Hello, some questions I have: -Is this radio the factory original radio, or has it been replaced? -Is there any non-factory equipment in the vehicle, such has an alarm system? -Has there been any physical damage, accident damage or otherwise with the vehicle? Those questions are key to learning more about the problem. There is no guessing I could do without knowing the answers - and guessing really doesn't go anywhere anyway. I would recommend seeking guidance at a local shop near you that can learn about your vehicle and perform needed testing. Something is obviously keeping the audio circuit "live" when it is not supposed to be. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
