On Star module

I have a 2022 GMC Denali Ultimate and the OnStar module has already failed with 10,000 miles on it. Took the dealer 4 days to diagnose. Now the problem is that this OnStar module used in soooo many GMC and Chevy vehicles is not available and no ETA as to eventual availability. And my forced OnStar subscription for a non-functioning unit runs out in 2025.

To further add insult, there are over 30 new GMC/Chevy vehicles with the exact same module needed sitting on the dealer's lot. To have a 2022 high$ vehicle with an almost new common part needed unavailable with no idea when the part will be available is ludicrous. Checking online, many folks with my new era vehicles have waited months for their OnStar module to become available.
