The infotainment system loses all audio through the speakers intermittently. when this happens I also lose the Safety warning chimes as well. shutting off the vehicle for an extended period of time resets something and it resumes normal function. I have contacted GM customer service and spoke to 3 different representatives and requested an escalation to a Senior Advisor, which i was told could take up to 4 days to hear back. the vehicle has 800 miles and is 1 month old, this has occurred 4 times. it has not been looked at by the manufacturer as i am waiting for return communication. Other than no sound, everything else on the touch screen seemed to be working normal, but im no technician to determine that. i feel this is a safety concern as i travel with my 13 month old daily.
