General Motors

Good Evening, I purchased a new 2020 Silverado from Southtowne Chevrolet in Newnan Georgia about 6 months. Within the first month we took the truck on a drive up to Ohio, it was little cool and cross wind, and I got a continuous Flute noise sound in the cab on my visit and back to Georgia. Seem's like the flat land, it will flute up often ecspecially on windier days. Then at times you don't hear the sound (the wind has to hit it just right). It does it on the driver side door only. I don't get anything on the passenger side. I have taken it to Southtowne twice now, and the service manager claims he cannot duplicate the sound. Problem is, it happens on windy days. It's like I need the service manager to be there on a windy day with me, so he can hear it for himself (I totally get you can only fix what you hear), but I provided videos of some of the sounds. I really feel they simply need to start by replacing the door seal, and lets go from there. This is a new truck and I shouldn't be getting this sound already (I bought a new 2017 from there, and I recently traded in for to have the 4X4 Z71, and the other one didn't have this same flute sound like this). The test drives the service manager did both times both on non-windy days. I provided these videos to the service desk, but get the response the service manager didn't hear anything.

I didn't think to get the videos in Ohio since we just got the truck, it was much louder with it being more flat. I'm hoping someone can help me get this resolved, because I cannot let myself hear this for the next 5 years, or I will just get rid of it and never go back to another one.
