OnStar Guardian app highlights

Roadside Assistance* 

Your loved one is in a friend’s car, and they’ve run out of gas. Or the battery died. Or they’re locked out. Your loved one’s about to save the day. The OnStar Guardian app helps them out, bringing the help they need to any car or motorcycle. Hey, it may even save the day for you. 

Mobile Crash Response 

If you or a family member is in a crash, the phone’s sensors will let us know. We’ll call your phone to check on you and send First Responders to where you are, in any car or on a motorcycle. 

Emergency Services 

Whenever you or your family need us, 24/7, just open the app and push the red Emergency button. We’ll be there to give you advice or get First Responders to you. You can even enable Siri®* or Google Assistant* on your phone to get help with just the sound of your voice.

Location Services* 

Did your kid make it to school? Is your partner still at the store? We’ve got all the answers. You can see each other on a live map, share and save locations, and set notifications to tell you if they’ve left or arrived at a place you specify.

OnStar Guardian for Motorcycles

Worry less. Ride more. We’re here for you, even on your motorcycle.
