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
Fuel level is incorrect not 539 miles to empty nor 85% last connection was 8 hours ago
I’ve open the app like 6 times today and it doesn’t connect to update status.
