Cancel Onstar: Easy Method
What is Onstar
Service overview
OnStar is a connected-vehicle service offering roadside assistance, emergency response, vehicle diagnostics and security features through in-vehicle systems and the OnStar Guardian mobile app.
How it is provided
OnStar is primarily a U.S.-based service integrated into compatible vehicles and has mobile-app functionality for some features.
New Zealand customers typically access support via the same member services channels used internationally.
How to cancel Onstar
Cancel OnStar Guardian app services
- Open the OnStar Guardian app and follow the in-app cancellation flow to end Guardian app services.
- Alternatively call OnStar Member Services at 1-888-466-17827 or press the blue OnStar button in your vehicle to cancel Guardian services.
- Important: deleting the app from your phone does not cancel the service; you must cancel within the app or by phone/blue button.
Cancel main OnStar subscription (vehicle service)
- Online: Sign in to My Account → My Plans → select "cancel my plan" to stop the main subscription.
- By voice: Press the blue OnStar button in the vehicle to request cancellation or call 1-888-466-17827.
- Note: The main OnStar service cannot be cancelled via the OnStar mobile app; use the website, phone, or blue button.
What happens when you cancel
Service access after cancellation
If you cancel, service access depends on your billing and plan type. Prepaid or bundled services typically remain usable until the end of the paid period.
Renewals and billing
Cancellation prevents future automatic renewals but does not necessarily reverse charges already billed.
Keep cancellation confirmations and monitor bank statements to ensure no further charges occur.
Data and account records
Your account and vehicle records may remain on OnStar systems per their data-retention policies. Request account closure details from Member Services if required.
Will I get a refund?
General refund policy
No refunds are available for prepaid plans or for services that were included with vehicle purchase or lease; you can use service until the paid period ends.
Exceptions and older/ international terms
- Older OnStar Terms & Conditions have allowed refunds for unused whole months or remaining days when services were paid directly in advance, unless excluded by purchase/lease terms.
- Some international terms indicate prorated refunds may apply for services paid directly in advance, less any service fees. Free services typically receive no refund.
How to request a refund
Ask Member Services for clarification when you cancel and keep written confirmation. If you paid in advance and believe a prorated refund applies, request it explicitly.
Onstar plans and pricing
Availability of NZ pricing
No publicly available New Zealand-specific pricing (in NZD) for OnStar plans in 2024/2025 could be found.
U.S./Canada pricing exists publicly; NZ-specific pricing appears unavailable or is not published.

Your consumer rights in New Zealand
Relevant laws
New Zealand consumers are protected by the Consumer Guarantees Act (CGA) and laws on unfair contract terms and misleading conduct.
These laws require services to be supplied with reasonable care and skill and not to be misrepresented.
How these laws apply to OnStar
- If OnStar fails to provide promised assistance (for example, roadside support) this may breach the CGA or be an unfair term.
- Lack of clear refund or cancellation terms could be challenged under unfair contract or misleading conduct provisions if they are not transparent or applied unfairly.
Practical steps for NZ consumers
Document service failures, keep all communications and receipts, and raise the issue with OnStar Member Services first.
If unresolved, consider contacting Consumer Protection NZ or seeking advice from Citizens Advice Bureau or a legal adviser.
Customer experiences
Positive reports
- Some users report life-saving assistance and prompt guidance in medical or emergency situations.
- Positive cases often cite timely emergency response and helpful agent guidance.
Negative reports
- Many reviews cite poor customer service, difficulty cancelling and recurring charges despite cancellation attempts.
- There are frequent complaints about long delays or failure of roadside assistance and unexpected billing or trial charges.
How to interpret reviews
User experiences vary widely; consider both positive emergency outcomes and recurring operational complaints when assessing value for your situation.
Documentation checklist
Account and vehicle details
- OnStar account email and password (if available).
- Vehicle VIN and licence plate, if applicable.
- OnStar account number or subscription ID (from invoices or My Account).
Proofs and records
- Purchase/lease documents showing OnStar included with vehicle, if applicable.
- Payment records or bank/credit card statements showing charges and dates.
- Screenshots of cancellation attempts, chat transcripts, email confirmations.
Common mistakes
Assuming deleting the app cancels service
Many users uninstall the OnStar Guardian app expecting cancellation. Deleting the app alone does not stop billing or end services.
Trying to cancel the main service via the mobile app
The mobile app cannot cancel the main OnStar vehicle subscription. Users who try this may believe they cancelled when they have not.
Not retaining confirmation
Failing to obtain and save written cancellation confirmation makes disputes harder to resolve if charges continue after cancellation.
