Get a better understanding of how Automatic Crash Response works in your vehicle and what steps are taken in the event of a crash.

How It Works

Using built-in vehicle sensors, Automatic Crash Response is designed to detect and gauge the severity of a crash without any input by the driver. The feature is available 24/7 and connects Members with a live Advisor.


If a crash is detected, details such as location, airbag deployment, speed and direction of impact are available to an Emergency Advisor who can send for help even if the driver can’t. Injury Severity Prediction allows Advisors to inform First Responders about what they may encounter before arriving on scene.


Plan Requirements


The Automatic Crash Response feature requires an active plan. It is included with the following plans: Premium; Essentials; and Safety & Security.

How is the Mobile Crash Response in the OnStar Guardian app different from the in-vehicle OnStar Automatic Crash Response?

The OnStar Guardian app uses sensors in your smartphone to determine if it’s in a moving vehicle before it begins scanning to detect a crash. The Guardian app is then designed to alert an OnStar Emergency Advisor, who will call your phone and contact First Responders as a Mobile Crash Response. In-vehicle Automatic Crash Response is a service that uses embedded hardware and vehicle sensors that are designed to detect a crash to alert an Emergency Advisor. The in-vehicle Automatic Crash Response is available in any properly equipped GM vehicle, while the OnStar Guardian app extends this service to any vehicle you drive, ride in or share.
