Cancel OnStar

Log in first, then open this link. It is the My Plans page OnStar's own cancellation page points at. Pick the plan, review it, then click cancel my plan. Service runs to the end of the billing period and prepaid or vehicle-included plans get no refund.

Go to OnStar’s cancel page

Opens shop.onstar.com in a new tab. Their login page forgets where you were going, so open this after you are signed in.

Open My Plans

Review the selection and click cancel my plan
