  1. I have a 2019 Silverado High Country with the 6.2L. I have had several issues with my center display. At 2500 miles it started making vertical lines on the display. A few minutes later it shorted out and started smoking. It has spent quite a bit of time at the dealership and they replaced the gauge cluster and the center display but it just failed again two days ago at 3800 miles for the second time.
  2. I have the 2019 High Country and have heard the high pitch noise. But, mine happens when I am on light throttle at around 36-37 mph, nothing to do with the a/c for me. I can seem to make it happen or make it stop by the amount of throttle I give it at this speed. Maybe my issue is completely different. I have also had the radio center display fail, even let the smoke come out of the wires. I have video of that but I won't share it yet. The dealer replaced the display and the gauge cluster and it just failed the center display again. This hasn't even been two weeks since the replacement.
