I am having the same problem on my 2011 Dodge Journey Express. I have the 4.3 UConnect. I have been able to duplicate the problem whether I was using satellite, fm radio or CD. Just randomly on start up the volume is blaring. I can tap the radio dial down and it will immediately show something like 5 even though it was blaring. I took it to Dodge and of course they had never heard of the issue. I did manage to record the problem on my cell phone and it did on the video. They were stunned at the dealership. They have ordered a new radio and I really hope this fixes the problem. But after finding this forum, I'm worried.
