I have experienced the same thing. Radio works fine and then one day simply there are no sounds in the vehicle, no radio, no turn signals, no backup assistance warning. Just like Odewang reports turn vehicle off exit lock and came back to vehilce started vehicle and it worked. This is a ghost problem and GM has a difficult time finding a ghost. Anyone else experience this?
Thanks.
usadelta,
I am sorry you are experiencing this issue with your vehicle. This issue may be due to a software anomaly and may be resolved with a reprogram to the latest software for the audio amplifier.
This is just a suggestion and is not meant as a diagnosis. I recommend consulting with a certified technician for an official diagnosis. They should be able to provide additional information after inspecting the vehicle.
Please keep us posted.
