The OnStar Guardian™ app is the latest innovation from OnStar®, a name that has stood for safety for more than 20 years. Now, the power of OnStar is on a smartphone — for everyone in your family.

With OnStar Guardian, you and up to seven other people will have access to OnStar Emergency-Certified Advisors, ready to help, 24/7. When you and your family download the OnStar Guardian app, you'll have a little peace of mind in the palm of your hand.


Mobile Crash Response
You and your loved ones can get help in a crash — even if you can't ask for it. OnStar Guardian is designed to use smartphone sensors to detect a crash — in any vehicle. In these situations, the app can automatically connect to an OnStar Emergency-Certified Advisor. Our Advisors can then contact First Responders and provide them with your location — and they’ll stay on the line with you until help arrives.

Roadside Assistance
Have the confidence to let your family go anywhere — in any vehicle — knowing that OnStar is ready to help. Get a tow, a battery charge or help with a flat tire, or have your doors unlocked. You can even get fuel if you run out of gas.

Emergency Services
OnStar is there for you and your loved ones. The red Emergency button provides access to an Emergency-Certified Advisor 24/7. Our Advisors can assess a situation, provide help, contact 911 as needed and stay on the line until First Responders arrive.

Location Status
Stay close to your loved ones, even when you're apart. You and each person you add to your plan can share their location with the entire group — and see locations right in the app.
