Frequently asked questions

See All Guardian App FAQs

What is the OnStar Guardian app?

The OnStar Guardian app* gives you and your family OnStar® safety services that go where you go — in any car, on a motorcycle, out for a walk or even in your home — all right on your phone.

What services are included with the OnStar Guardian app?

The Guardian app gives you OnStar safety services right on your smartphone, including:

 

  • Mobile Crash Response for any vehicle or motorcycle
  • Roadside Assistance* for any vehicle or motorcycle
  • Emergency Services, including 24/7 access to OnStar Emergency Advisors*

 

 The app also lets you invite up to seven loved ones to the "My Family" group*. Everyone gets the safety services within the app as well as Location Status,* which includes:

 

  • Viewing each other’s location on a live map
  • Real-time location updates
  • The ability to share your location
  • Cellphone battery life status

 

How does Mobile Crash Response work?

By using the sensors in your smartphone, including the accelerometer, the app can detect when you’re in a moving car or on a motorcycle. When a crash is detected on an Android device, the app can automatically connect you with an OnStar Emergency Advisor who can contact First Responders. When a crash is detected on an Apple® device, the app alerts an OnStar Emergency Advisor who will then call your smartphone, requiring someone to answer the call.

 

Enabling location permissions within the app allows an OnStar Advisor to identify your smartphone’s location and contact First Responders for help, even if you can't ask for it.

Who is eligible for the OnStar Guardian app?

Anyone can download and use the OnStar Guardian app. You can download the app from the App Store®* or on Google Play™*.

Where can I use the OnStar Guardian app?

Currently, the app services are available in the U.S. and Canada only on select Apple and Android devices. OnStar Guardian app service coverage is limited and may vary with conditions and location. Service availability, app features and functionality can also vary by device and software version.

How much does the OnStar Guardian app cost?

The Guardian app is included with OnStar One* and OnStar Protect* plans starting at $19.99/month.* You can download from the App Store* or on Google Play™*.

Is my account information secure?

We maintain reasonable and adequate technical, administrative, and physical security and confidentiality measures designed to help protect your information from unauthorized access or acquisition. In an active emergency situation, Emergency Advisors may share your information, pursuant to the OnStar Guardian App Privacy Statement. Your information will only be shared with emergency service providers — like law enforcement and Roadside Assistance and ambulance providers. Consult the OnStar Guardian App Privacy Statement for more information.

Can I use the same login information I use for the myChevrolet, myBuick, myGMC or myCadillac mobile app?

Yes. You can use your myChevrolet, myBuick, myGMC or myCadillac mobile app login.

 

If you have an existing GM Account, you can use your login for the Guardian app as well. You don’t need to create a new GM Account for the Guardian app. 

How do I get the OnStar Guardian app?

Simply download the app from the App Store* or on Google Play*. Follow the on-screen prompts to set up your OnStar Guardian service.

What smartphones are compatible with the OnStar Guardian app?

The app is currently compatible with select Apple and Android devices (Android 8.0+ and above and Apple iOS 14.0 and above as of March 2023). The Guardian app requires devices to have GPS, accelerometer, gravity sensor, and gyroscope.
