Onstar Module Needs Replaced
Same issue. I have a 2022 Sierra 2500 AT4. 6 months over the 3 years, but 5500 miles under the 36K. OnStar wont connect at all. No lights (Red or Green). Dealer wants almost $800 to diagnose and replace the unit. Unacceptable. What's up OnStar, any plans to rectify this? Seems to be a lot of newer vehicles with this issue....
