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.
Same on my 2025 Colorado Trail Boss. Has not updated in two months and the onstar is being paid for every month.
