I just had the dealer look into it. They said the window issue described above by Randy wasn't the case in my truck. So not sure what is next. Separately, I had a knocking sound behind me when I drove. I thought maybe it had to do with the window issue Randy described. It turned out there was an issue with the rear leaf spring. They did have to order a part, but it was a simple fix. I do have to give credit to the service department as the only way they found it was to put microphones under the truck to isolate where the sound was coming from when it drove. I really appreciate their patience in the discovery process!

Randy, Thanks so much for that. It falls into the category of forever to figure it out and a minute to fix. I will check this out and post here what I find out!

I have a 2023 Sierra 1500 Denali. The wind flutter is significant. I've opened both rear windows and the back cab window, it still flutters. I then open the front windows and it doesn't go away until everything is open. My dog rides in the back seat, and I can't leave a window down for him (or both windows) without the flutter issue. Does anyone have any ideas? I was wondering if wind deflectors would make a difference, or??? Unless it's really hot, I prefer to open a window over a/c, but this situation makes it a problem. Thanks! Ron
