Body problems of the 2021 Chevrolet Tahoe

Sunroof continues to collect water in the drain. I have had it blown out but it continues to happen. It is a matter of time before it begins to leak into the truck. In my research, this is an extremely common problem/design flaw.

There is a serious cabin air pressure issue in this vehicle. When driving at any speed with the windows up, there is a booming inside the cabin, as if the passengers are inside of a subwoofer. My theory is that the headliner panel has too much flexibility in it due to the ceiling air vents. When driving, it is likely the headliner is bouncing up and down, creating the booming air pressure. Within 2 weeks of delivery of this new car and daily driving, my passengers and I developed serious ear issues which we attributed to the car. It got to the point where I would immediately have pain and ringing in my ears just driving a very short distance. None of my other cars including suvs cause or have ever caused this issue. It is important to note that with all 4 windows rolled down, the problem does not happen. It's only when the windows are up. I have the LS trim without the sunroof.
