Problem is fixed now!!! No more fluttering noise. Get the Range AFM!!!! Sent from my iPhone using Tapatalk

Hopefully your heat shield replacement will fix it. Can’t wait to hear more about it. I’m sick of this fluttering noise... Sent from my iPhone using Tapatalk

I found this PIP5570 on the Yukon/Tahoe site. Try the fix on my Yukon but no luck. https://www.tahoeyukonforum.com/threads/2017-denali-fluttering-when-accelerating-video.91039/page-7 Sent from my iPhone using Tapatalk

Hi, I believe I have the same issue. Can you confirm that replacing the heat shield resolved chatter/fluttering noise?
