OnStar Guardian


Get Key OnStar Safety services that give you help in a crash, assistance when you have car trouble and much more — right on your smartphone. For 25 years, OnStar® has led the way with on-the-road safety and security. The OnStar Guardian™ app carries that power beyond the vehicle: the power of OnStar on a smartphone — for every member of your family.

OnStar Safety & Security Members receive the OnStar Guardian app as part of their plan. If you don’t own a GM vehicle, you can try it for 30 days, and after that, it is only $15 a month.

Plus, you can share these benefits with up to 7 loved ones at no additional cost.


Mobile Crash Response
Help in a crash — even if you or your loved ones 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 who can send First Responders, all while staying on the line until help arrives.

Roadside Assistance
Your loved ones can get a tow, a battery charge, help with a flat tire or have their doors unlocked. They can even get fuel if they run out of gas.

Emergency Services
The red Emergency button gives your family access to an Emergency-Certified Advisor 24/7. They can assess a situation, contact 911 and stay on the line until First Responders arrive.

Location Status
View and share locations with any family member you add to your plan — right in the app.
