Onstar abuse by household member. Hacked

We take the safety & security of all of our Members very seriously. Some precautions we take include associating specific actions with different roles on an account as well as having a verification process any time we discuss account information with Members. We also have a privacy policy that you're able to learn more about by visiting this link: https://www.onstar.com/us/en/privacy_statement. With that, the only way someone would be able to access a vehicle location is if they were added to the account by the Account Owner or had access to the Owner Center account utilizing the Owner's account information. Based on your post, it seems this situation has ceased. In the event it is ongoing, we highly recommend resetting your Owner Center password as soon as possible in addition to re-evaluating the Members listed on your account. We can help you if you send an email to socialmedia@gm.com with "ATTN: OnStar Community/Acct Help" in the subject of your email.
