What happens when you cancel
Service access after cancellation
Once you cancel, your OnStar service typically continues through the end of the current billing period. You retain access until that date.
Account and renewal
Cancellation stops future renewals; OnStar does not automatically continue service past the current paid period after cancellation.
Data and messages
OnStar may retain account and vehicle data per its policies. If you need data removal or have privacy questions, contact OnStar support directly.
Will I get a refund?
Refunds for vehicle-purchased or leased plans
OnStar does not offer refunds for plans that were prepaid as part of your vehicle purchase or lease. These are generally non-refundable under OnStar terms.
Refunds for other prepaid plans
For other prepaid plans, OnStar will refund unused whole months or remaining days on a prorated basis, unless the terms exclude a refund.
There is no mention in OnStar’s published terms of a universal 14-day automatic cooling-off refund period; refunds are conditional and handled per OnStar’s terms.

Your consumer rights in South Africa
Cooling-off and unsolicited services
South African consumer law, including the Consumer Protection Act, typically provides a cooling-off period for unsolicited or direct-marketed services. The standard period is generally seven days.
Billing and unfair practices
Local law protects consumers against unfair billing and unauthorized debit orders. If charges continue after cancellation, you may dispute them with the provider and your bank.
Recommended next steps locally
- Keep all cancellation records and dates.
- Contact OnStar first to resolve billing problems.
- If unresolved, escalate to your bank (stop/chargeback) and to South African consumer protection bodies.
Customer experiences
Common positive points
Many users value OnStar’s emergency response and roadside assistance when it works as intended.
Features such as automatic crash response and remote services are frequently cited as valuable.
Common complaints and warnings
Some users report repeated billing after cancellation, long call wait times, and cancellations not being processed correctly.
Reviews cite difficulties obtaining refunds, unfulfilled tows, and lack of trial-end notifications. See user reviews for examples.
Documentation checklist
Before you call or cancel
- Account username/email and password for My Account or the OnStar app.
- Vehicle details: VIN, license plate, and model year.
- Billing statements showing recent charges (for dispute evidence).
During and after cancellation
- Record call date/time, advisor name, and any cancellation reference number.
- Save confirmation emails or screenshots from the app or website.
- Keep follow-up correspondence and bank statements showing any continuing charges.
Common mistakes
Assuming cancellation is instant
Many users expect immediate termination. In practice, service usually continues until the end of the current billing period, so confirm the effective end date when you cancel.
Not keeping proof of cancellation
Failing to save cancellation confirmations or advisor details makes disputes harder if billing continues. Always record evidence.
Expecting automatic refunds
Assuming you will automatically receive a full refund is a frequent error. Refunds depend on how the plan was purchased and OnStar’s terms; vehicle-included plans are generally non-refundable.
