Used to be Chevy Lover

I have a 2019 Chevrolet Traverse and I have been having the same issue of no sound, no audio from anything. No blinker sound, no door chime and no radio. It has been going on for several months, it was just going off every once in awhile and continuously got worse, now it will go off for days at a time then come back in. Makes a popping sound when it goes off and comes back on. Have contacted Chevrolet and have still not got it resolved. My car was just out of warranty when the issue started. I have taken to local Chevrolet dealer for diagnosis, but I really feel like they are just guessing. Saying water is running from HVAC onto module and shorting it out, their fix is diversion of water for a lot of $$$ but who is to say the said module will even last if thats the case and I'm sure it is not a cheap part. Getting very discouraged that Chevrolet won't get to the bottom of this issue and fix the problem. Buying a brand new vehicle, you would expect this would be addressed as I see I am not the only one with this problem. Has anybody gotten it fixed and it stay fixed, I'm not convinced that it isn't a software problem.
