OnStar breaking up, they can't communicate with my car

Dealerships are great for assistance when you are experiencing hardware concerns with your OnStar system. If the LED near your OnStar button is red, that is a key indicator that there is something wrong with your unit. The best initial step is to push you blue OnStar button to have a live Advisor perform an On Demand Diagnostics (ODD). From here, we can see if an additional trip to the dealership would be necessary.

Do you experience this concern only during a specific time such as speaking with a live Advisor? If you can provide our team with additional details in an email, we can look into your account on our end and see what further steps we can provide. You can reach us at socialmedia@gm.com and we ask that you have your subject line as ‘ATTN: OnStar Community/Bulging_Eye’ so we can reference back to this post.
