Common issues
Can I cancel OnStar online or in the app?
No. OnStar does not offer online or in-app cancellation. You must call 1-888-466-7827. Be prepared for a retention script and possible hold times.
Will cancelling OnStar affect my vehicle's emergency services?
Yes. Emergency services (automatic crash response, roadside assistance) are part of OnStar. After cancellation, these services stop. Your vehicle's built-in features (like navigation) may still work depending on your car model.
