I got my 2018 Compass Sport last October. It also has the 5.0 Uconnect. Starting in about February of this year I've had issues with the Uconnect shutting down and rebooting. Happens more regularly when I listening to my phone through the system, but has on occasion happened when it's just the radio playing. I haven't noticed any other problems with speakers or shifter light (MT). Also, I've noticed over the past 6 months or more that my USB buttons appear to be greyed out. The front one still charges my phone when plugged in, but doesn't light up when it used to before. I've never used the one in back.
I'm not overly frustrated with it, and will have them check things out on my next oil change. I'm almost positive they're going to tell me "that's how it is supposed to be", even though its not.
