OnStar Crisis Assist services give GMC owners with active OnStar service a means to facilitate emergency assistance and other resources in the event of adverse weather or other emergency situations.

In times of emergency – especially when facing extremely dangerous weather like a tornado or hurricane – communication is critical. GMC owners can leverage the capabilities of OnStar – including its Crisis Assist service – to find the help they may need in the wake of a powerful storm.

“Our team actively works to help manage any crisis – especially ones in the wake of these storms -- for our OnStar customers, or anyone else who’s able to get to someone with an OnStar-equipped vehicle,” said Catherine Bishop, Global Emergency Services manager at OnStar. “Whether it’s addressing an emergency, providing evacuation routes, helping find an available shelter or a hotel -- whatever the case may be – we’re prepared to lend a hand.”

While it’s important to take steps to properly prepare for dangerous weather (some tips for hurricane preparation can be found here), OnStar advisors can provide assistance when navigating the aftermath, including the following:

  • Connect with emergency first responders: Traditional emergency call centers can quickly be overwhelmed with call volumes after a dangerous storm. OnStar can provide a direct, alternate means of connecting with emergency responders and requesting aid.
  • Good Samaritan Calls: Likewise, you can use OnStar to reach first responders in order to help others in need of assistance.
  • Evacuation guidance: OnStar advisors can help you find the best available routes out of an area impacted by severe weather.
  • Seek shelter: OnStar can also help you locate available shelter facilities, hotels, or other alternative appointments, if needed.
  • Communicate with friends and family: if others are concerned for your location and well-being, OnStar advisors can help you connect with them.

Remember, OnStar Crisis Assist Advisors are available 24/7 to help members affected by severe weather. For more information, please press the blue OnStar button in your GMC vehicle, visit, or call 1-888-4ONSTAR.
