2018 Terrain Denali, periodically something happens to the infotainment center when switching modes and the sound stops, doesn't matter if you try radio, media, nav etc, just no sound. If you try and play with the volume you can visually see that it's changing in the display but you still can't hear anything. Happens every so many days and probably impossible to duplicate if I go to the dealer. Only way to fix it is to completely turn off the vehicle and then restart it, then the sound is back until next time. I have noticed it a lot (but not all the time) when I hang up my phone from a call. Phone is paired with infotainment center and works fine via BT. Anyone else having a similar issue or had it and got it fixed?
