Have you checked your battery contacts? This doesn't sound like a common problem and I'm glad the Radio came back on. You made a good decision purchasing additional coverage . The additional 12 months/12K factory coverage will come in handy as usually the dealer asks for a nominal charge to attempt to find an intermittent problem (the worst kind) waived if the problem is located. Keep in mind not all aftermarket plans will cover Audio or Video components so take it in soon. Hopefully this won't happen again!Only own the car for 2 weeks so not sure if this is a common issue. 2014 2LT RS with 39k miles. I was parked waiting for my daughter to finish tennis practice. Engine off, key in accessory, windows and sunroof open, listening to some music and iPhone plugged in to the USB in the center console. My daughter gets in the car and I start the engine. When I do, the radio screen shut off and music stopped, but this time it didn't come back on. It always does that, then the "MyLink" logo comes on and it picks up the music where it left off, but this time it was blank. I pressed "Nav" to bring up the GPS, i press power button for the radio, I even put it in reverse and got no back-up camera. I shut the car off, took the key out, opened the driver door, then closed it and started the car like I was just getting in. Still no screen, no radio/music. everything else worked like normal.
I got home, shut it off, checked the fuses, none were blown. I started the car again and the screen, radio and everything worked like normal. Is this a common issue or some sort of fluke? I bought the car certified pre-owned from a dealer so its under warranty and i extended the bumper to bumper warranty to 6yr-100k. I have no problem taking it to the dealer for service, but I hate wasting time with intermittent problems where it randomly won't work for me, but works again the first time they start the car.
