2012 Silverado Wind Noise Nightmare.

[JRD761]

If it only happened on the corners I would assume that it was because of wind pushing the water thru the spot. Why couldn't the tech spray it with water and then use a nozzle on an air hose to simulate the wind pushing the water?

I don't think it's the wind.. I think it's the body flexing that creates the gap.. I'm not 100% sure though. I'll bring this idea up to them

Probably even more to it than that. The lateral sheer forces of cornering would cause the entire vehicle chassis to flex in ways that you can't replicate with water and air pressure alone. As an illustration, think of what happens when you slightly twist an un-taped cardboard box. Even a small amount of sheer force can cause the box lids to not line up properly. On a vehicle chassis, if the chassis has any flex as a result of wind and gravitational forces that aren't directly below the cab (as would happen when cornering) the door seals may not be lining up properly.

Is this something that they'll be able to fix? Or is it just a flaw with the truck and they'll never be right?

I would think replacing the seals and adjusting the doors would fix the issue, but I'm not a Chevy Mechanical Engineer. It's probably what they're trying to figure out. If they can't repair it, I'd call Chevy Corporate and explain the situation and ask for assistance. You DID buy it new, and you can show your vehicle is not behaving as others... which makes it a factory defect. Either way, it's a horrible problem to have, and I don't envy you.

Good luck!
