2025 Buick Enclave - Ongoing OnStar / Battery Drain Issue

This doesn't sound at all like something we hope to hear, @davidbx1.

To start, send us a private message to OnStar_Support with more details including your full name, VIN, mileage, email, phone and dealership name/location. Simply select the envelope at the top right of your screen to do so. Any other details you can share on where things stand at the moment are also appreciated to help our investigation. We will be watching to hear from you.
