How to cancel OnStar

OnStar is a subscription service bundled with many General Motors vehicles that provides emergency assistance, navigation, and remote vehicle features. You can cancel it by calling OnStar directly, through your GM vehicle's infotainment system, or by contacting your vehicle's dealership. The process takes a few minutes, and cancellation is effective immediately or at the end of your current billing cycle, depending on when you request it.

OnStar subscriptions come in different tiers — some are included free for a limited time after purchase, while others are paid monthly or annually. If you are paying for the service and no longer want it, you have the right to stop at any time without penalty, though some annual plans may have different terms depending on when you purchased.

Key Takeaways

  • Call OnStar at 1-888-466-7827 to cancel over the phone; this is the fastest method and takes about five minutes.
  • You can also cancel through your vehicle's infotainment system by navigating to Settings and selecting the OnStar menu, though phone cancellation is more reliable.
  • Have your vehicle identification number (VIN) and account information ready before you call.
  • Cancellation takes effect immediately for month-to-month plans, but annual plans may have different effective dates depending on your contract terms.
  • OnStar may offer a discount or pause option before processing cancellation; you can accept or decline.

Calling OnStar to cancel by phone

The most direct way to cancel is to call OnStar's customer service line at 1-888-466-7827. Have your VIN ready — it is printed on your vehicle registration and insurance documents, and also visible on the dashboard at the base of the windshield on the driver's side. You will also need your account PIN or the phone number associated with your OnStar account.

When you reach a representative, tell them you want to cancel your subscription. They will ask why you are canceling and may offer you a reduced rate or a temporary pause instead. You can accept or decline. Once you confirm cancellation, the representative will provide a confirmation number and tell you when the cancellation takes effect — usually the same day for month-to-month subscriptions, or at the end of your current billing period for annual plans.

Keep the confirmation number for your records. If you are charged after cancellation, you can reference this number when you contact OnStar to dispute the charge.

Canceling through your vehicle's infotainment system

Many GM vehicles allow you to cancel OnStar directly from the vehicle's touchscreen or dashboard menu. Press the OnStar button on your steering wheel or look for the OnStar icon in your vehicle's main menu. Navigate to Settings, then Account, then Subscription or Billing. Select the option to cancel or manage your subscription.

This method works on newer GM vehicles with updated infotainment systems, but not all vehicles support it. If you do not see the option in your menu, or if the system does not complete the cancellation, call OnStar instead. In-vehicle cancellation can sometimes fail to process, so calling is the safer choice if you want confirmation that day.

Canceling through your GM dealership

You can also visit or call the dealership where you purchased or service your vehicle and ask them to cancel your OnStar subscription. The dealership staff can initiate the cancellation on your behalf, though they will still need your VIN and account information. This method is useful if you are already at the dealership for service, but it is slower than calling OnStar directly.

Some dealerships may charge a small fee for this service, though many do it at no cost. Call ahead to ask whether there is a fee before you visit.

What happens after you cancel

Once your cancellation is processed, OnStar features will stop working. This includes emergency calling, roadside assistance, remote door unlock, and turn-by-turn navigation through the OnStar system. Your vehicle's built-in navigation may still work if it is powered by a different system (such as GM's native navigation), but OnStar-specific features will be unavailable.

If you cancel a paid subscription mid-cycle, you will not receive a refund for unused time. If you cancel an annual plan, check your contract terms — some annual subscriptions allow cancellation without penalty, while others may charge an early termination fee. Ask the OnStar representative about this before you confirm cancellation.

If you want to reactivate OnStar later

You can restart your OnStar subscription at any time by calling 1-888-466-7827 or through your vehicle's infotainment system. Reactivation usually takes effect within a few minutes. If your vehicle originally came with a free trial period and you canceled before that period ended, you may not be able to restart the free trial — you would need to pay for a new subscription.

Pricing for OnStar subscriptions varies by plan and region. When you call to reactivate, ask the representative what plans are currently available and what the monthly or annual cost is.

Frequently Asked Questions

Will I be charged after I cancel?

No, your subscription should stop immediately or at the end of your current billing cycle, depending on your plan type. If you are charged after cancellation, contact OnStar with your confirmation number and request a refund. Disputes usually resolve within one to two billing cycles.

Can I cancel if I still owe money on my vehicle?

Yes. OnStar is a separate subscription from your vehicle loan or lease. Canceling OnStar does not affect your financing or lease agreement. If your vehicle is leased, check your lease terms — some leases require OnStar to remain active, though this is uncommon.

What if I cancel but my vehicle still shows OnStar is active?

This sometimes happens if the cancellation has not yet synced to your vehicle's system. Wait 24 hours, then restart your vehicle. If OnStar still appears active after a day, call OnStar again with your confirmation number to verify the cancellation went through.

Do I need to cancel if I sell my vehicle?

Yes. The new owner will need to set up their own OnStar account, and you should cancel yours to avoid being charged. Call OnStar and provide your VIN to end your subscription before the sale is final.

Is there a penalty for canceling early?

Month-to-month subscriptions have no early cancellation penalty. Annual plans vary — some allow cancellation without penalty, while others charge an early termination fee. Ask the OnStar representative about your specific plan before you confirm cancellation.
