I just started having this noise at 7500 miles on my 2022 AT4 Sierra and my local dealer said they know there’s a problem but when they contacted GM for the warranty repair it was not authorized. The dealer said GM doesn’t have a fix for at this time and this was just last week. I’m in love with my truck but this whole BS about not fixing something under warranty makes me want to sale it. Any help from GM would be appreciated
