Payment

Thank you for reaching out to share this. Please try going to Experience.gm.com > Select the account icon > Sign in to My Account > Scroll to the bottom of the Account Overview page and select Payments > You will be taken to the Payments and History page where you can Add, Edit, Remove or Switch payment methods. To edit – Once you’ve selected the Edit link, a pop-up window will appear where you can edit the details of a stored card. Change details as necessary and select Save.

Note: You cannot edit details of a stored bank account. To make changes, you will need to delete and re-add the bank account to your payment methods.

Should this still not work for you, please send a private message to OnStar_Support so we can look into this further. Just select the envelope icon at the top right of your screen to get started.
