New 2025 Equinox another OnStar telematic module is out instance

My issue was a slow buildup. It started with my remote start from the app occasionally not connecting. Then some of the apps occasionally had difficulty loading content. Then the GPS started showing that I was in places that were 50-100 miles away.  That is when I pressed my OnStar button, which did not work.  So I called OnStar.  They told me that since the OnStar button was still green, to take the car to my dealership & tell them OnStar said it was the telematics module.  I brought it to the dealership. They sent me right home because they said it would take some time to even diagnose the issue and the diagnosis will determine how long a repair will be. I had to make an appointment to come back when they had a loaner available (today).  I was told I will get a call on Monday with an update.
