Direct answer: OnStar subscriptions can be canceled online or through an Advisor, but canceling generally stops future renewal rather than creating a mid-period refund. Prepaid plans and service included with a vehicle purchase or lease are not refunded under the standard cancellation rule, while some vehicle-sale or transfer situations can be reviewed separately.
The fastest way to read OnStar is to start with “Cancellation can be self-service,” then verify “Service continues through the billing period.” The first rule controls the opening decision; the second checks whether the same OnStar transaction follows a different timing, channel, or product branch. The example “Monthly customer cancels halfway through the billing period” shows the consequence: OnStar says the service continues through the billing-period end; cancellation is not described as a prorated cash refund.

OnStar policy checkpoints that control the outcome

How to carry out a OnStar cancellation or refund request
OnStar action 1: Identify whether the plan is prepaid, monthly, promotional, or included with the vehicle
At OnStar, action 1 is “Identify whether the plan is prepaid, monthly, promotional, or included with the vehicle.” The OnStar checkpoint “Cancellation can be self-service” makes the confirmation date worth recording.
Test that OnStar action against “Monthly customer cancels halfway through the billing period.” OnStar says the service continues through the billing-period end; cancellation is not described as a prorated cash refund. Keep the final OnStar screen or email if the real result needs follow-up.
OnStar action 2: Cancel from My Account or contact an OnStar Advisor and save the confirmation
For OnStar, perform “Cancel from My Account or contact an OnStar Advisor and save the confirmation” only after matching the deadline to “Service continues through the billing period.” That OnStar rule is: After cancellation, OnStar says services continue through the end of the current billing period.
The case “Prepaid plan customer cancels early” shows how OnStar can behave in practice: The standard OnStar page says prepaid plans are not refunded for ordinary cancellation. Use this OnStar confirmation to verify the same branch applied.
OnStar action 3: Record the end-of-service date shown after cancellation
The OnStar workflow now reaches “Record the end-of-service date shown after cancellation.” Record the billing owner before completing it, because “Prepaid plans are not refunded for ordinary mid-period cancellation” controls this OnStar branch.
Afterward, compare the OnStar result with “Customer trades in the vehicle with paid time remaining.” A transfer may be possible, and OnStar says a refund may apply if an eligible transfer cannot be completed. A mismatch should be documented before another OnStar request is sent.
OnStar action 4: If selling, trading, or losing the vehicle, ask whether the remaining plan can transfer before asking about a refund
Use “If selling, trading, or losing the vehicle, ask whether the remaining plan can transfer before asking about a refund” as the next OnStar action. Pair it with the OnStar rule “Vehicle transfer situations are different,” especially the product type attached to that rule.
For the example “Plan was included in a lease,” OnStar specifically says plans included with a vehicle purchase or lease are not refunded under the standard mid-period cancellation rule. That OnStar example gives a concrete result to compare with the completed action.
OnStar action 5: Verify that no future renewal is scheduled and keep any transfer or refund reference
Before OnStar action 5, write down the effective date. Then carry out “Verify that no future renewal is scheduled and keep any transfer or refund reference” under this OnStar checkpoint “Canceling and refund eligibility are separate questions.”
Use “Monthly customer cancels halfway through the billing period” as the post-action OnStar test. OnStar says the service continues through the billing-period end; cancellation is not described as a prorated cash refund. Preserve the OnStar evidence until the expected change is visible.

Verify the final OnStar status
