Cancellation FAQs
What is the fastest way to cancel Onstar?
Start with the cancellation link above. Follow this order: 1) Open My Plans; 2) Cancel the plan; 3) Handle a sold vehicle; 4) Confirm the service end. Do not leave after merely submitting a request—continue until you can see an effective date or receive confirmation.
What should I prepare before cancelling Onstar?
Have the account holder’s name, account number, billing email or service address, and requested end date ready. Check the company name on your statement so you use the correct billing route. Deleting the Guardian app does not cancel service. Automatic Crash Response and Emergency Services stop when service ends.
When should I cancel Onstar, and when will billing stop?
Timing rule: OnStar says you may cancel at any time. Billing outcome: Services continue through the end of the billing period, then OnStar safety and emergency services shut off. Act before the stated cutoff, save the displayed end date, and check the next statement rather than assuming the request stopped an already scheduled charge.
Will Onstar charge a fee or give me a refund?
Cancellation fee or remaining balance: No cancellation fee stated. Refund rule: No refunds for prepaid plans or plans included with a vehicle purchase or lease; other eligible situations may receive a prorated refund under current terms. Ask the company to state the final charge and refund separately in writing; cancellation alone does not automatically create a refund. Equipment: Built-in vehicle equipment stays with the vehicle; no return is stated.
How do I prove that I cancelled Onstar?
Keep plan status, cancellation confirmation, billing-period end date, refund response. Save copies outside the company’s app or account in case access disappears. Your proof should show the request date, effective date, affected service, and confirmation or reference number.
What should I do if Onstar keeps charging me?
First compare the charge date with the saved effective date. Contact Onstar using the link or contact details above and send one clear timeline: cancellation request, confirmation, promised end date, and new charge. Ask for written correction and a refund. If the company does not resolve it, promptly give the same evidence to your payment provider and ask about its dispute deadline.
