2. Select the Profile Icon with your initials in the top right corner and navigate to 'Account Overview'
3. Select 'Payments & Billing Info' from the left side menu

 

If you're unable to update your information via your GM Account, you may also reach out to our live Advisors by phone at 1-(888)-4ONSTAR (1-888-466-7827) or by pushing the blue OnStar button in your vehicle for further assistance.
