I have a 2022 GT-Line with sunroof. My driveway is up a slight hill and whenever I back out of my driveway I get a pop/knock sound coming from behind me and occasionally the next turn I make after this happens it will pop/knock again. Haven't pinpointed yet if it might be the rear glass of sunroof, something to do with trunk, the "hat rack" area next to rear glass, or somewhere else, but defintely sounds like coming from behind driver. There are also bars inside the trunk along the inner/upper portion of trunk area (not trunk lid) that I thought could be moving around, but they all seem to be secured pretty tight. Anybody experienced this yet? 1500 miles on car and only issue with car so far.
