Radio shuts off and no sound from turn signals
I have the same problem. It happens when temps outside get cold. Today the temp was -2F on the way to work and the radio never turned on. It blinked a couple of times when the traction control would kick in, but then immediately turn off again. I drove an hour to work with no functioning radio. It also stops the sound of the turn signal.
On the way home, the temp was a bit warmer, but again, no radio. One thing I found that is a temp workaround is shut the car off, take the key out, and put it back in and start the car. Unfortunately, it is difficult to do on the highway. I did get a call and the phone connected through the bluetooth, but I could not hear or answer it as there was no working connection to the radio.
The car has had this problem since I bought it, but never to the extent I've seen it the past couple of days. It starts when the temps drop below 40-50F.
I'll be taking it in to the dealer shortly.
And I'm in Michigan, so the temps should be low from Sept-May, so this is a problem.
Update: I hit the rear defroster button as mentioned in an earlier post and the radio powered on. I turned off the rear defroster and the radio continued working.
Latest update:
Took the vehicle in for warranty repair of radio. They were able to duplicate problem, called service center and found a software upgrade that solved the issue. Radio works great now.
