2025 Silverado RST 3.0 Diesel - No Audio

[Rick Crockett]

Twice now, the audio in the truck has quit.  No radio, can't hear my phone call and even cannot hear the blinker.  Turning the truck off does not help. But works the next day or next time that I get into the truck.  Not sure how long it takes.

Press and hold the call hang up button on the steering wheel for about 15-20 seconds.  That will hard reboot the radio.

 

If it keeps doing it, take it in.  There is likely an update that might fix it.

Would that also fix not hearing the clicking of the blinker?

I had the same lack of audio this year on my 2020. I drove it to the dealer, they verified, checked for codes and there was none. They gave me an appointment for a few days later. 

I shut it off and restarted with the same lack of audio. It sat overnight and the next day everything worked fine and continues to work fine months later. 

I'm sure someone on here has the answer to this.

Turn signal chime is run via the radio.  Has been for almost 30 years on GM vehicles.

I did this to mine. It fixed it.

My loaner had that happen (no sound from anything) last week. "Fixed" itself an hour after shutting it off and then restarting. A 2026 Sierra 1500. Hasn't happened since.

I had this happen several times on my truck.  Tried the reset/reboot with the steering wheel button and still lost audio and turn signal sound.  Took the truck into the dealer, they did a software update on the radio and now it has worked ever since.  Also built in Google Maps would shut down several times on a 1 hour trip, since the software update Google Maps has worked good as well.

Have you been avoiding the "over the air" updates?   I had 3 or 4 in the last 3 months on my 2024, 2 in one day recently.  Don't know what they accomplished.   I had the no sound from radio once last year and they rebooted system, took about 15 min. Did not even need a tech, service advisor did it.  Lots of these gremlins with the software driven vehicles. The Sun goes behind a cloud and a computer glitch surfaces.

In my 21 Silverado or now my 25, I never ever have had an over the air update come through, and I do manually go into the radio and check for the updates, maybe once a month or so.  For the no radio volume and turn signal noise, they told me they had to use the scan tool and preform the update, which took several hours.  For the Google Maps update, the service advisor did that one outside in the parking lot, which did take quite a while as I am an Iphone user so I had to download the Google email app, create an account, and then go through with the updates by logging into my radio.
