How to Cancel OnStar

Step-by-step instructions

1. 1

   Sign in to My OnStar plans with your GM account

   Go to shop.onstar.com/account/my-plans, the link on OnStar's cancel page, and sign in on the GM account page it sends you to. OnStar says you can use your GM Account, OnStar account, vehicle mobile app or GM Rewards login. Then select the vehicle whose plan you're ending. The myChevrolet, myBuick, myGMC and myCadillac apps show your plan details and connect you to an Advisor, but OnStar's own cancel steps run through this web account, so use a browser.

2. 2

   Open My Plans and select the plan

   Under OnStar, open My Plans (the button reads View My Plans), find the plan you want to end and click Cancel plan on it. OnStar's steps work on one plan at a time, so if the car has two, say Protect and Connect Plus, repeat these steps for the second. Plans belong to a vehicle, so a second GM car needs its own pass.

3. 3

   Skip any offer and confirm with Cancel My Plan

   The page is headed "Canceling your plan?". It says that by cancelling, you will no longer have access to the services it lists for your vehicle, effective a date at 11:59 PM ET, and asks "Why are you cancelling?". A Limited-time offer box may show a discount on your plan for a few months, with an Accept offer button; on older, prepaid or AT&T data plans it suggests switching plans instead (Activate Discount), and the cancel button reads Continue with Cancellation. These labels come from OnStar's site code, not a live account. Read the list of services, since it shows what you're losing, skip the offer and click Cancel My Plan. OnStar shows "Your request to cancel is processing" and emails a confirmation, and its cancel page says your services continue through the end of your billing period. Keep the email, and check My Plans again a day later: an r/BoltEV member who cancelled by phone was later told "my account wasn't actually cancelled."

   Heads up: The offer is a retention play: you keep paying, for the same plan or another, discounted only for a few months. Accepting starts the discounted plan instead of the cancellation.

   Or cancel by phone or the blue OnStar button

   OnStar's cancel page and its User Terms both accept a call: push the blue OnStar button in the car, or call 1-888-466-7827 (1-888-4ONSTAR), day or night, 365 days a year. TTY users can call 1-877-248-2080. Use this if My Plans shows OnStar's older message "You cannot cancel your service online", which its store and some of its FAQs still carry, if the online cancel fails (OnStar's error text says to call to complete it), or if the plan you want to end isn't listed. An r/OnStar member who cancelled years ago called it "an extreme hard sell to stay", and an r/BoltEV member says the Advisor offers a cheaper plan, though another said theirs "didn't even try to talk me into subscribing." Ask for the cancellation to be confirmed by email.

   If this applies to you

   If you sold, traded in or returned the car, or it was totaled

   Call 1-888-466-7827 with your OnStar account number or VIN and the date the car was sold, traded or totaled. OnStar's User Terms say you must tell GM when you sell or transfer a vehicle, "to avoid being charged for Services after your sale or transfer", and its account pages tell anyone who no longer owns the vehicle to call to deactivate it. A plan you paid for can move to another OnStar-equipped car if the primary driver stays the same. If it can't move, OnStar says a refund, if applicable, will be given for the remaining time you bought. A plan that came with the car stays with the car.

   Call to disconnect the car if you want it off OnStar entirely

   Cancelling a plan doesn't unplug the car. OnStar's own cancel text says: "Your vehicle will remain connected to your account and basic services after you cancel. Call 1.888.466.7827 to disconnect." Its User Terms say an Advisor can give you instructions to disable the services in your vehicle. On a 2025 or newer car, OnStar Basics comes with the car for 8 years; you can decline it, but OnStar says it can't be removed from the vehicle. Disconnecting ends Automatic Crash Response too, so weigh that first. For the data side, an FTC order finalized January 14, 2026 (matter 2423052) requires GM to let U.S. drivers request a copy of their data and its deletion and to switch off precise location collection where the car supports it. GM's U.S. Consumer Privacy Request Form is at gm.com/consumer-privacy, or call 1-866-697-7482.

   If you pay for the OnStar Guardian app on its own

   Guardian comes with the One and Protect plans, so it ends when they do. A separate Guardian subscription is cancelled in the Guardian app or by calling 1-888-466-7827, OnStar's Guardian FAQ says, and deleting the app from your phone does not cancel it.
