Hi guys l have a 2014 Silverado that is done all crazy things no sound , my cluster will go black dead ,

 light on the steering wheel and comands no response i can not get phone calls  engine will  be driving ok but no info . I have a bully dog conected to the  truck so I get speed and info from it . Then after two or three seconds will be back and go until I get to stop . The dealer could not find the problem so I replace the HMI module and the receiver I replace the cluster too I did the big three upgrade check all the grounds  and a new battery. The cluster is working fine now but I still lose the sound,if someone have any advice thank you

Mine has been doing pretty much the same thing for a few years, 2015 Sierra 3500 SLT. had it back to the dealer twice. First time they said the GM Engineers told them that it needed a software update. Did that and same issue the next day. Second time they had it for two days and said they couldn't get it to do it. Go figure. It will switch to the menu screen and back to radio screen back and forth, it will also change to the clock and eventually freeze up. I can still hear the radio the whole time. It will also switch the the screen between the gauges to the radio station. Now it just started popping up trailer brake service on the dash on and off several times. No trailer hooked to it. I have noticed it to be more when it is hot out side. It won't do it all winter. When the cab of the truck cools off it all will pretty much stop. It will do it almost all the time if I use the remote start in the summer, but again, not in the winter. I have been trying different little things to prevent it from doing it and if I let the chime ding three times before starting, it usually won't do it. may not have anything to do with it but it seems to work. Lol. If it gets to irritating to me, I will pull over and shut the truck off, remove the key and wait till all the computer's go to sleep and restart it. returns it to normal most of the time.

I'm having the same issue as the original poster.  2015 Chevy 2500HD LTZ.  Now that I'm reading this, it does seem to happen more on wet or humid days.

I'm thinking it's the steering wheel clock spring?  Has anyone had it happen while sitting still?  For me it always seems to be a slight turn that sets mine off.  It is EXACTLY the same problem as the video that the original poster posted.

 

I think I still have an extended GM warranty (bought it used in 2018).  I want to look into this as it's pretty annoying, and embarrassing.

It’s not the radio there’s a radio control module under the glove box the connections are loose all you do is push them up a bit till it clicks took my brother and I 3 weeks to figure this bullshit out!!!
