New 2024 Suburban no sound from speakers

Last week I purchased my wife a new 2024 Suburban. Upon driving it off the lot I noticed no sound was coming from the speakers. I test drove it and it did not have that problem. I turned around and took it right back in. I was obviously pretty upset being that it was so expensive and brand new. They told me it just needed a software update. Well its done it twice since then and again tonight. Zero sound. Any advice on what I should do here? I'm pretty ticked off and not sure what action I should take. I'll certainly notify them and tell them I expect it to be remedied, but the dealership is two hours away and its a pretty big inconvenience having to drive it up there. Any thoughts on how I should handle this?

If you have a Dealer closer you may try them. You can take it to any GM dealer in the US which includes Chevy,GMC, and Cadillac.

With the car being that new, I'd be a royal PIA to the Dealer, until it is fixed once and for all.

Sadly, they gave me the "This is a known issue and a software update should be coming." I asked them why they didn't tell me before I drove it off the lot if it was a known issue and they said they didn't know. I then asked when the software update was coming, and they didn't know. Ultimately I told them to unwind the deal as I wasn't spending the money on this vehicle that wasn't working properly out of the gate and while I know issues happen, it was unacceptable for a new vehicle. They protested, but ultimately when I threatened legal action they relented without much else to say. So now we are back in our 2017 model and will keep looking around.

I bought my first GM product in January (2024 Tahoe) and over the past few weeks I have had intermittent issues where the sound is not working (XM and FM radio, bluetooth phone calls). Typically if I turn the car off and on it will correct itself but today it just kept happening. I took it to a local Chevy dealer and they were not sure what the cause was. Does anybody know how to get this fixed?

The dealer told me that there wasn't a known fix for it. If you do a google search on it it seems to be an issue that tons of people have.

So is this just a permanent issue that customers have to accept? I would be surprised if such an issue can persist continuously without any planned fix.

I don’t understand why it happens in some cars but no all of them. I’d look to replace the radio/nav head. Reprogramming the whole truck
Have you tried the control alt delete shutdown of the nav/radio unit. Clear the cache memory

You can try doing an infotainment unit reset to see if that helps. You put the vehicle in park, then hold down the "end call" button on the steering wheel for about 10-12 seconds. Let go, and you'll see the infotainment unit reset. I've had to do that a couple of times due to some wonky stuff with the Google maps or the speed limit signs not showing up, and it has worked for me. Might work for your issue.

Any other hack tidbits for these trucks? I have a 2023 Sierra SLT Premium BabyMax.
I’ve had to have two radio/audio updates with a couple weeks or purchase last year.
We absolve this truck, and have experienced 34mpg a few times. But mostly my heavy foot and Texas road speeds in the 80’s keeps it in the 28.5ish range
