My radio volume goes nuts and the controls go unresponsive, The unit brings the volume up to max I can not hear emergency crews if they are using the siren. This also creates a safety issues as now I am taking my eyes off the road to try and stop the problem. The infotainment system is failing yes the truck is available for inspection. I have taken video of the problem and sent it to the dealer. The vehicle has not been inspected by police or insurance rep, as far as manufacturer as this truck has been back to the dealer more then 4 times I fell that would be the manufacture as they are certified by GM. GM knows that there is an issue with the infotainment system, not sure why they have not done a recall on this unit. No warnings are given before this happens. This problem first showed up when the truck had about 3,000 miles on it I bought the truck brand new.
