Onstar Button not working
Bought a new to me 2025 Traverse, the Onstar button has no light on it and nothing happens when any of the buttons are pushed. I have disconnected the battery to try to get it to reset and that did not work. Any ideas on what is going on or how to fix it?

Going through the same thing with my 2024 GMC Acadia. Sent it to the dealership and says it is telematic control module (Navigation Module) that needs to be replaced.
