Mobile Crash Response

The Guardian app is designed to use your smartphones sensors to detect a crash and alert an Emergency-Certified Advisor. The Advisor will call your phone and can contact first responders and provide them with your location all while staying on the line with you until help arrives.

Emergency Services

Someone 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, contact 911 as needed and stay on the line until first responders arrive.

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.

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.
