OnStar basic plan 8 year coverage

Hi @sweetsum,
That situation is definitely confusing, especially when you’re getting mixed answers from OnStar support. What usually causes this is a backend account or provisioning issue, where the vehicle technically has the Basic Plan, but certain features (like Google Maps traffic data) stop working due to a sync or entitlement error
In similar cases, people have had success reviewing their connected-services status and account entitlements using connected vehicle support tools
to better understand what’s enabled versus what’s restricted. I’d also recommend asking OnStar to re-provision the vehicle services on their end and confirm eligibility in writing, since the Basic Plan does list navigation and traffic updates.
Hopefully that helps you get some clarity and pushes them to fix it properly.
