I have a 2018 GMC Terrain Denali that has 3,000 miles and I am having some issues with my overhead lights, sunroof and garage openers not working after my vehicle is sitting outside in the sun. Is anyone else having this problem?

Well that's a new one...The control module in the upper console must be the fault..Go to your dealer..this is a warranty issue for sure..and welcome.

Thank you for your response. I have been to my dealership and they said there are no bulletins for the problem I am experiencing. My service person said he was going to contact GM. I have emailed GM as well, but have not heard back from them yet. I emailed my service person just now about a possible faulty module for those upper controls. I hope they can fix it soon, since I cannot utilize those controls.

I sure hope they get it resolved soon..as I said; it is covered by the warranty..so they need to get it going..good luck..BTW; where are you from?
