If you’re no longer using OnStar or want to stop being billed, you might be wondering how to cancel your subscription. Whether you sold your vehicle, finished your free trial, or just don’t need features like crash response, vehicle tracking, or in-car Wi-Fi anymore—canceling OnStar is the right step.
Many users say it’s not easy to cancel through online methods, but once you know the options, the process is straightforward.
Does OnStar Make It Hard to Cancel?
OnStar doesn’t currently allow users to cancel their service directly through their website dashboard or mobile apps. While you can manage parts of your account online, cancellation still requires speaking to a support agent or using your vehicle’s OnStar system.
You cannot cancel your OnStar subscription through:
- The OnStar website account login
- The OnStar Guardian or RemoteLink app
- Email or customer chat (in most cases)
Instead, you’ll need to use one of the official channels below.
How to Cancel OnStar (Follow These Options in Order)
Here are the official methods you can use to cancel your OnStar service. Try the one that’s most convenient for you.
1. Call OnStar Customer Service (Most Reliable)
The most direct way to cancel is by calling OnStar support. Dial:
1-888-466-7827 (1-888-4-ONSTAR)
Have your account details and Vehicle Identification Number (VIN) ready. Once connected to an advisor, clearly state that you want to cancel your subscription. They may ask for your reason and offer discounts, but you can decline and confirm cancellation.
Ask the representative to send you an email confirmation for your records.
2. Cancel From Inside Your Vehicle (Hands-Free Option)
If you’re near your car and it still has OnStar service active, you can cancel directly from the dashboard.
To do this:
- Sit in your vehicle and turn it on
- Press the blue OnStar button
- Wait for a live agent to answer
- Say “Cancel my OnStar service”
- Verify your account information and confirm the request
- Ask for confirmation via email
This is often the fastest method if you’re still using OnStar inside the vehicle.
3. Contact Your Dealership (If You Sold or Traded In Your Vehicle)
If you’ve sold or traded in your car, let the dealership know that OnStar is still linked to your name. While dealers can’t cancel your subscription, they can help you start the process or transfer ownership.
Even if your car is gone, you should still call OnStar directly to close your account and unlink your payment info.
Important Notes Before You Cancel
Before completing the cancellation, here are some helpful reminders:
- Cancel before the next billing cycle to avoid being charged
- Free trial plans also renew automatically unless canceled early
- Once canceled, your remote features like lock/unlock, navigation, and crash response will stop working
- You can reactivate OnStar anytime later using the same account or another plan
- Check your email for confirmation to make sure your cancellation is processed correctly
What Happens After You Cancel OnStar?
When you cancel, all premium OnStar services are turned off. That includes:
- Emergency response and automatic crash alerts
- In-car Wi-Fi and remote diagnostics
- Vehicle tracking, app-based lock/unlock, and location sharing
- Turn-by-turn navigation and vehicle health reports
Your vehicle will continue to operate as normal, but the smart services will no longer be active. If you ever want to return, you can reactivate your plan from the OnStar website or by calling support again.
Conclusion
Canceling your OnStar subscription takes a bit of effort, but it’s not complicated once you know where to go. The fastest way is to call OnStar support or use your car’s built-in OnStar system. If you’re unsure whether the cancellation went through, always ask for an email confirmation.
