In a crash, OnStar is there for you.

Because every moment matters.

In a crash, OnStar is there for you.

Because every moment matters.

Help in a crash. Even if you can’t ask for it.

Car crash detection. It matters. In the moment of a crash, a fast response is everything. It’s why we created OnStar Automatic Crash Response.* Using built-in vehicle sensors, a specially trained OnStar Advisor can be immediately connected into your car to offer help. Even if you don’t respond, our Advisors can give First Responders your location and use Injury Severity Prediction to tell them the likelihood of serious injuries. OnStar Advisors are also trained and certified* to provide medical assistance until help arrives, ensuring you won’t face the emergency alone. Simply put, OnStar crash detection can save lives.

Dr. Stewart Wang, a trauma surgeon, lives by the mantra that getting the right person to the right place at the right time makes all the difference.

Life is unpredictable. It’s why we built the Safety & Security Plan.

Life can send us curveballs in all forms. We’re here for you. Lost? We’ve got you. Fender bender? We’ve got you. Flat tire? We’re on it. The OnStar Safety & Security Plan* gives you Turn-By-Turn Navigation*; GM Roadside Assistance* (including towing); and if you’re in a crash,* we’ll check in and request help, even if you can’t ask for it.
