MyGMC app not updating mileage, fuel etc
I’ve got a green Onstar light, checked truck for updates, says it’s up to date, and have rebooted iPhone and deleted/reinstalled app. No change. 2025 Sierra 1500 SLT diesel
Having the same issue. Called onstar as well and did a manual scan, but they couldn’t connect and had no solution.
