OK Cody2019TB, I will pass this along to our service rep and other's that have a similar truck. I am sort of like hcop33 in that it does not bother me right now. But that could change and now I have a potential solution if I want this fixed before warranty expires. Thanks

I have found the thread that explains the problem I was wanting to describe. I will wait now to see if GM can really come up with a real fix. Good to know now its coming from the plastic spoiler. No sunroof here

UncleDave, I have same sound coming from my 2019 RST Z71. I was going to explain in same way as if an acorn dropping from a tree. Hoping we can keep this thread going until we identify the source. Thanks
