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


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,* 7 Crisis Assist*7 and 24-hour Roadside Assistance,*8 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.

You may not be in a disaster every day, but when you are, you should know as a Member of the OnStar community, we have your back.

Advanced Diagnostics, OnStar Smart Driver, Remote Access and Location Manager

Vehicle Manager

Be prepared for the road ahead

OnStar has many ways to help you manage and maintain your vehicle. It all starts with Advanced Diagnostics,*15 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*19 services are now featured on your myChevrolet, myBuick, myGMC or myCadillac mobile app,*22 so you’ll never have to worry about locking your keys in the car again.

Advanced Diagnostics proved a lifesaver for 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.

“I use it to send directions from my phone to my car, locate my car when I can’t find it with the horn and lights feature and start my car on those cold Michigan mornings, even when I’m nowhere near it."
