I am having the exact same problem with my truck. It started at around 3000 miles, I told the dealership, brought it in and they said they could not duplicate the sound. So I took videos of it and emailed them. They are saying the same thing, that it is normal. That is not an ok answer in my book. You pay 100k for a truck and expect everything to work right. I’m thinking on contacting my extended warranty and have them check it out. Pretty sad that GMC is trying to say this is normal.
