Module failure

Allow us to learn more about the situation with your OnStar module. Once connected, we can best assist working toward a resolution to your concerns behind the wheel, @Thomase2025. We can provide added support and serve as a liaison between you and the trained technicians of your preferred dealership while they address your vehicle for repair. 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. Just select the envelope at the top right of your screen to do so. Any other details you can share on where things stand currently with your vehicle are also appreciated, as context will help us investigate. We will keep an eye on our inbox. 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.
