Hi All, I have a 2015 mirage DE. Have had this issue a few times, when its hot out, like today over 90, car sits in a work parking lot, windows closed, I go out to it and the radio is off, heat/AC work just fine. Screen is blank. In a few minutes of open windows it will come on, either driving or just sitting and letting the interior cool down. Only happens in the heat, otherwise works fine, over the 4 years I've had it, radio "cut out" 2-3 times going over a bump, never really bothers me because it comes back on LOL. I don't know if anyone has seen this or thinks they are related. Thanks for any input.
