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

I am seriously questioning the real value of onstar if it’s systems are faulty. Cut losses and cost. GM please remind me of the benefits here.

I have a 2026 2500hd diesel
My app doesn’t update sometimes it can be over 12days, been through power cycles and uninstalled/install app multiple times. When I open the app up top left the fuel shows 539 miles and 85% that’s been there since the first time I downloaded the app and it’s in correct . Not sure why it has never changed. Onstar can’t figure out how to fix the issues, as I’ve talked to them numerous times over the past 3 weeks.
We have two ford vehicles and the ford pass app is on the money every time you open it.
GM needs to get their team together and figure out the fix as it’s seems like a lot of people have issues with the app not being updated or inconsistent reading.- Advisor_CharlyModerator

The app isn’t updating can be days or weeks, it tells me to drive at least 2 min I’ve drove for 1 hr and still no refresh update.

That's frustrating. I have the same issue with my Silverado RST. It synced when I first setup after purchase, then didnt connect for 25 days. Finally called onstar and they did a manual scan which did update the odometer and oil life indicator (but nothing else updated) Going on 10 days without syncing again.

Did you figure out a solution yet? Having the same problem.

I had called OnStar again last Friday (the 19th) and after talking through the issues I've had with it since purchase she flagged it all for support to take a closer look. I hadn't heard back afterwards but as of yesterday morning and today both to and from work its been working and I'm getting updates after I'd turned the vehicle off.

I have everything updating on my myGMC app except for Fuel Level. I have deleted the app, reinstalled, signed in, logged out, logged in again, made sure my OnStar plan is connected and I still cannot get it to update. Technical support was not able to help me either. Has anyone found a solution for this problem?
I have had my truck for 2 years with everything working fine and this problem just started recently.

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.

ONstar support passed the case to the Engineering team and they resolved within a day. Not sure how but I woke up a couple days later and it was working and has continued working since. I got the email from Engineering that it was resolved about a day later but no details on what exactly was done

Fuel level is incorrect not 539 miles to empty nor 85% last connection was 8 hours ago
- Chuckster131New Contributor II
I’ve open the app like 6 times today and it doesn’t connect to update status.

My issue was sent to a higher level support team. I never talked to anyone on that team but the next day, everything was updating as it should. I guess the Tier 2 support team can do something in the background on Onstar's end to fix it.

I sure hope they do get this addressed!! I’m sure it’s not that difficult to fix the bugs, as they charged enough for these trucks.
Ford pass app like I said before works flawless
