Telematics Module/Onstar Not Working 2022 GMC YUKON

I have a 2022 GMC Yukon Denali with 49,000 miles. The vehicle included 3 years of connected service.  The service expired over the summer and I didn't renew opting to try Apple Car Play for navigation.  The Onstar communication, clock and connected services regarding maintenance etc remained functioning. I decided to renew the subscription last month and the vehicle lost all communication after.  I reached out to Onstar and was informed I needed to take to the dealer.  Dealer states the Telematics module is bad $1275.00 for replacement.  Not covered under any warranty.  The same day I renewed the subscription I received a vehicle status email so communication existed until the subscription renewal was done.  I was told to reach out to GM. I contacted and was provided a sorry no help reply.  Does anyone have any suggestions on how to navigate getting a covered repair on known problem?
