Months without OnStar Telematics

I bought a new 2026 Chevy Traverse less than a year ago. During my first year of ownership, the vehicle has spent 42 days in the shop after the ESC light tripped for the brake system. A few months later, now I'm now dealing with a failed Telematics module with no ETA for replacement parts. It's been 30 days since my dealership put in the order. My vehicle included a tech package with internet and OnStar service, neither of which work anymore. Remote start? Gone. Locate the vehicle via App? Gone. God help us if we're actually in an accident and need OnStar help. Can't connect.

I'm losing value by the day with no end in sight.

I cannot understand WHY replacement parts are not available for a new model. It's such a poor reflection on the GM brand.
