MyGMC app not updating vehicle status since OnStar had to refresh my wifi signal a week ago.
My problem started when I renewed my Onstar connect subscription on my 2021 Silverado 1500 LT, June 4th 2025. The buttons and map work fine so far, just diagnostics don't.
Yup same issue, OnStar said my original premium plan wasn’t offered anymore. They gave me the new comparable plan and since then the diagnostic information has not updated.

I have the same problem and it started when I tried to update my OnStar subscription on June 24, 2025, for 2015 Chevy Tahoe, not only did it take more than 3 weeks just to get my account updated so that I could purchase the subscription. Once the subscription was updated the My Chevy App fail to update. I have gone through troubleshooting with On Star technical support twice, after the first session the milage did update however the fuel/milage fail to update. They have checked my system twice with no errors. Today I went through that process again still no fuel/milage update. They requested that I drive the vehicle and if it doesn't update call back again and they will escalate my case to a higher level. I believe something happened during the software migration process from Chevy to OnStar and they don't know how to fix it yet. This is very disappointing I've a loyal paying customer since 2016 now I'm frustrated
