Dear [Volt owner],
We’re happy to have you as part of the OnStar®1 family and we appreciate the confidence you have in us. In our continuing effort to provide exceptional customer service, we will be performing a systems upgrade during the early morning hours of Sunday January 22, 2017.
While we are working hard to make the transition as seamless as possible, there will be intermittent periods of time when your vehicle’s mobile app will be unavailable.
Please be assured that during this time OnStar services including emergency, security, navigation and Hands-Free Calling will continue to be provided. As always, OnStar advisors will be available to provide remote door unlock, remote horn and lights, or contact Roadside Assistance. Simply press your blue OnStar button or phone 1.888.4.ONSTAR (1.888.466.7827)
We apologize for any inconvenience this may cause.
OnStar Customer Service Team
