Same issue here, radio goes out n no audible on turnsignals then jst comes back on after driving a bit very random. ..
Just got my car back from Koons Chevy (one of the biggest in the country) after several hours with GM tech support everyone finally discovered a bulletin on : "REPROGRAM RADIO PER PI0972 CODE 80506" that led to a software upgrade that's supposed to fix this problem. Waiting to see how she runs tomorrow. Meanwhile everyone might want to run this by their service managers.
