There are crackling sounds coming from the wheel when going over humps. no power while driving or changing lanes it's worst when the ac is on, was burning gas like crazy, and shakes at 65 mph., the gas while escalating makes a clicking noise like 2 iron knocking together, and the dashboard including the radio, and telephone screens goes blank/black. from time to time from day one, the truck drop dead/blank in August 2021, AC comes on while not on time to time. the tire sensors read wrong, the door is making clicking noise, outside air is coming into the cabin, and exhaust fumes. It's very damp by my feet and under the steering under the driver's feet it's rusty, the safety alarms are on from time to time. From time to time the belt will squeeze while driving. Yes, the truck has been at the dealership lots of times, every time they claim they can't find the leaks or the problem! and refuse to set up any warranty repairs.

When I stop and try to turn key off it does not turn to off. Have to turn back on and try shifting neutral and back to park. Then try straightened wheel and eventually key will go to off position and take out key. Started few days ago intermittently and now more often. Mileage is 36317 so warranty if expired. I will not pay dealer for analysis since it should be covered under engine. Also have seen 100s of complaints with this online for 2016 thru 2019.

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.
