So we have had this issue since the first week or so of ownership. It is a random clicking sound, like a window trying to roll up after it's up already. I spoke with my father who is an engineer at GM, he checked around the people he knows up there and couldn't find anything on the issue. He referred me to the executive customer service reps who set up a dealer visit. Took it in, demonstrated the noise to the dealer and was told, no way to fix it at this time. I have included our invoice with the TAC number. If you are experiencing this issue, take it in to the dealer and give them the TAC number. Since this isn't throwing a code, GM will not give them authorization to investigate. This was told to me from the customer service rep from GM and the dealer. I was told I had to wait until, more cases are reported, it can be reproduced on demand or it outright fails. The more people we get involved and reporting the sooner we can get a field engineer out to actually troubleshoot the issue since the techs at the dealer are not authorized.
For those without picture access the TAC code is 8-2888465379.
