  1. i have a feeling it's the active noise cancellation which in theory should always work even with radio off. If you have any of the exhaust upgrades from GM on your truck that ANC software should be updated at the dealer. Perhaps see if you have any exhaust upgrade on your window sticker. If so make sure the ANC is updated from the dealer. Just an idea....
  2. I have the same issue. It's somewhere around the region of the start button on one of the adjoining panels. I only have a 150 miles on my Denali so i haven't had enough to time to pinpoint the exact location. I have been under the dash and screws "seem" tight so far on everything i checked out.
  3. I have the same rattle.  Is yours coming from somewhere around the start button?

      I can't tell to be honest.  It seems to be around the radio but deep in there.  I'm at about 1200 miles and started around 600 maybe.  I poked around under there but didn't find anything loose.  I'll get it to the stealership when I can.

      When i find my rattle location i will let you know.   I think we have the same issue.

  4. I have a 2019 Sierra Denali. I have a similar rattle in my truck. I only have 200 miles on it and it's driving me nuts. I thought it was the dash but now i'm localizing it to somewhere around the start button where panels come together. Still haven't found it.
