Frequently Asked Questions

Can I use OnStar if I have a mixed fleet or non-GM vehicle?

Yes. Non-GM fleet vehicles can receive OnStar support if they have an OnStar Fleet Adapter* connected. Visit our Add Ons page to learn more.

Can OnStar services be easily moved between vehicles?

OnStar plans cannot be moved or transferred between vehicles. If a vehicle is being cycled out and replaced with a new one, the plan on the outgoing vehicle is canceled, and a new plan must be purchased for the replacement vehicle.

Which features require an active subscription?

Certain telematics, security and Wi-Fi* features require an OnStar One Fleet* subscription. Visit our OnStar One Fleet page for more information. OnStar Fleet Basics* — covering vehicle health, EV diagnostics and remote commands — are included without a subscription, with Automatic Crash Response* (ACR) added for model year 2026 vehicles.

Can I connect OnStar with my current fleet management tools and software?

Yes. OnStar offers APIs and Data Services designed to integrate seamlessly with your existing telematics dashboards and fleet platforms. For supported partners, reach out to your OnStar Account Executive.
