I've got the same issue in my 2013 SE with the radio/audio popping and then all sound going away (no parking assist, etc). I also got in a fender bender on the passenger side front fender a few months ago, so now I am wondering if the issues are related. The time-to-pop after staring the car seems to vary a lot for me, with sometimes it going only minutes, and other times going hours without the audio popping and going off. I tried the fuse 69 pull, but it didn't seem to address the problem. I was thinking of trying the fuse 67 and 79 pull as well. Have you had any luck in resolving your problem?
