Warnings problems of the 2024 Chevrolet Trailblazer

The audio in the vehicle goes out the radio and the warning sounds for all the safety alerts. The vehicle has been to the dealer 3 times the problem still is occurring. The problem is random no telling when it will occur. I have called gm customer service they were useless. When the audio for the vehicle goes out when I turn off the vehicle if it sits most of the time the audio will come back on. Today 8/18/2024 the audio went out twice no sounds for anything blinkers, lane assist, side mirror alert, stop alert nothing. This also affects the radio. The service department tells me they are dependent on the gm it guys who in my assessment have no idea how to fix this. This is a safety and hazard problem with all sound going out for all alert systems.
