Automatic Crash Response, Emergency Services, Crisis Assist and Roadside Assistance

Emergency


The help you need, when you need it

Over the past 20 years, we’ve connected with more than five million drivers who’ve needed auto emergency services. And with Automatic Crash Response, Crisis Assist*2 and 24-hour Roadside Assistance,*3 we’re always there for you, even when you can’t call for help yourself. That’s how we were able to get emergency service providers to OnStar Member Christy Skelton when her vehicle was in a rear-end collision. Within minutes, first responders were on the scene to make sure that she was okay.

Of course, things happen on the road. But having the knowledge that no matter where you are, someone has your back? That’s the power of peace of mind — the peace of mind that OnStar can provide you and your family.

Protecting you both on and off the road

If your vehicle were ever stolen, you’d do everything in your power to get it back. With OnStar Stolen Vehicle Assistance,*4 you’ll be able to do a lot more. Theft Alarm Notification*5 can inform you if your car alarm goes off, and Remote Ignition Block™*4 can remotely prevent a thief from restarting the vehicle. And with Stolen Vehicle Slowdown,*4 an OnStar Advisor can remotely slow your vehicle if the authorities feel it’s safe to do so.

With OnStar, you’ll have the peace of mind of knowing that someone always has your back.

These services have already helped Members more than 26,000 times, including people like Ashley Haynes, a college student whose stolen car was recovered and returned the same day.

Take your world with you

Life moves pretty fast. But OnStar helps you stay connected and in control, even in places where staying in contact could be difficult. No matter where your journey takes you, we can help you stay safely connected with the people and things that matter most.

That’s why Chris Arace chose OnStar. As a professional photographer traveling across the United States, his car acts as his mobile office. But no matter where he’s headed, he’s never out of touch with the OnStar Wi-Fi hotspot*8 and Hands-Free Calling.*9

Advanced Diagnostics and Remote Access

Be prepared for the road ahead

OnStar has many ways to help you manage and maintain your vehicle. It all starts with Advanced Diagnostics,*10 which can self-diagnose and predict potential issues to give you peace of mind on the road. And if issues do arise, we can help with just a push of the blue OnStar button. Plus, Remote Access*12 services are now featured on your myChevrolet, myBuick, myGMC or myCadillac mobile app,*13 so you’ll never have to worry about locking your keys in the car again.

Advanced Diagnostics proved a lifesaver for OnStar Member Greg Heist when he encountered car trouble on the way to a family camping trip. The OnStar Advisor was able to immediately run a diagnostics check to confirm the problem and gave Greg directions to the nearest Dealer who could fix the issue. 90 minutes later, the Heists were back on the road and able to enjoy the rest of their vacation.
