I get the radio needs service/red light on rearview mirror once in awhile but everything else works (sat/radio/nav) just the uconnect features are down. Now the odd thing I stop the car, open the door for 20 seconds then close the door and start up and the uconnect is working. I also noticed this seems to happen when I am leaving the parking garage I use and I have to wait for other cars to exit before I do. Cell reception can be spotty or even no signal at times so I wonder if after I start my car and go to leave the Uconnect system has trouble getting it's initial signal and then times out/fails while I sit in line to exit the parking garage.
Either way I don't notice any other issues with my radio
