Reply To: 2022 Sierra Radio Cuts out

Not too sure if my 2024 Sierra 3500hd had the same exact issue as those others. Here’s how it was resolved. Day after taking my brand new truck home, started it up and there was no sound coming from the radio. This also affected the sound to the turn signals and other chimes. Everything worked but with no sound. 9 out of 10 times this would happen on start up only. Occasionally, on startup, it would work. Took in for service within the 1st week of ownership and was told needed a software update to the radio. Did that and took it home. Next morning, same thing, no sound. Went back in for service. We said we didn’t want the truck back until fixed. A week in a half later and several more software updates, they figured it out. It was a bad amplifier. Solved the problem and haven’t had another issue since. I hope this helps you out.
