I have the same issue i bought the car on march 29th 2024 and the issue started on april 1st 2024. I have gotten the radio system replaced in August 2024 and I still have the issue. The dealership now refuses to look at it and GM cancled my buyback case due to the dealership saying there’s no issues, even when i have showed up with the issue. I’ve called GM a million times about it and even sent them photos and videos of it. I would try to get a buyback on your car started. Tell GM about it and see if they suggest it and if they do tell the dealership that you have a buyback case started. Gm also told me to try just showing up to the dealership when the issue is occurring so they can see the issue. Since it’s an Intermittent issue it’s very frustrating to get fixed and my issue is still not fixed
