General Motors Expands Access to OnStar Guardian App

General Motors' OnStar Guardian mobile app1 is now available to anyone in Canada and the United States with an eligible plan and a compatible Apple®5 or Android™ smartphone device.

Now, customers in any brand of vehicle can stay protected and connected from anywhere and in any vehicle through the OnStar Guardian app. The expansion of OnStar Guardian, which first launched in June 2020, is part of GM's commitment to focus on opportunities beyond vehicle sales to make the road — and the world — a safer place.

With OnStar Guardian app, customers can access key OnStar safety services right on their mobile device and get help when they need it from an OnStar advisor. Customers can also share these features with others by adding up to seven additional family and friends to the My Family2 section within the app, giving them added peace of mind.

OnStar Guardian offers Mobile Crash Response, which uses smartphone sensors designed to detect crashes and alert an Emergency-Certified®3 advisor. The app will also launch new features this month in Location Status4, including the ability to save and share favourite locations on the app’s embedded map and receive notifications for destination departures and arrivals of family and friends.  

OnStar Guardian is currently available to OnStar members in Canada and the U.S. who are enrolled in a Safety & Security plan. For those without a GM vehicle, a standalone subscription plan is available to anyone in Canada and the U.S. Anyone can download the app and sign up for the service today through the Apple App Store and Google Play.
