Vehicle account not syncing to new vehicle

Thank you for reaching out, and welcome to the Cadillac family! Using existing OnStar or GM Owner Center credentials, owners are able to personalize apps on their vehicle and radio settings, which should be established on your new Escalade upon logging in. If you have confirmed that your login information is correct, our team would be glad to look further into the difficulties you are experiencing. Please send us a private message to OnStar_Support with your VIN and full name so we can assist. Just select the envelope icon at the top right of your screen to get started. By sending us a message, you consent to the information you provide being monitored and recorded by GM or those acting on GM’s behalf, subject to the GM Privacy Statement: https://www.gm.com/privacy-statement.
