If you would like to view your OnStar billing information, we recommend logging into your GM Account via Buick.com, Cadillac.com, Chevrolet.com, GMC.com or experience.GM.com and then selecting account overview. Here you should be able to locate your OnStar account information along with specific billing information. If you need any additional assistance, please feel free to email us at socialmedia@gm.com and we ask that you have your subject line as ‘ATTN: OnStar Community/Almost_Irish’ so we can reference back to this post.
