To cancel SiriusXM Guardian, call 866-635-8641, sign in to the Subscriptions tab of your SiriusXM Online Account Center at siriusxm.com, or start a live chat through the SiriusXM help page. All three routes work for direct-billed Guardian plans and take about 15 minutes once you’re through the retention offer. The online path is usually the fastest.
One boundary before you pick a method: if your Guardian subscription is billed through Apple, Google Play, or T-Mobile instead of by SiriusXM directly, you have to cancel through that third party. Apple subscribers cancel in their device settings, Google Play subscribers on the Google Play subscriptions page, and T-Mobile customers through their T-Mobile account. SiriusXM’s own channels can’t cancel a third-party billing arrangement.
What to Have Ready
For online cancellation, you need your SiriusXM email and password. For a phone cancellation, the agent verifies you using the phone number on the account and your vehicle’s seventeen-digit VIN, printed on the lower-left corner of the dashboard near the windshield and listed on your insurance card.
Before you start, sign in to your SiriusXM account or your vehicle brand’s owner portal and note two things: your current plan tier and your billing cycle dates. Both determine whether you’re owed a refund. If you’re still inside a free trial that came with the vehicle, write down the exact trial end date. The Mopar owner’s manual warns that if a credit card is on file, the subscription auto-renews at the current rate unless you actively cancel, so a trial with a card attached will roll into paid service on its own.
Canceling Online
Sign in to the SiriusXM Online Account Center, open the Subscriptions tab, select your Guardian plan, and follow the prompts. A retention offer typically appears as a pop-up before the final confirmation screen. Click past it and confirm. Screenshot the confirmation page and save the confirmation number.
Canceling by Phone
Dial 866-635-8641. You’ll move through an automated menu before reaching a live agent in the billing department. Say you want to cancel Guardian, provide your VIN and account phone number when asked, and decline any counteroffers. Write down the agent’s name, the date, and the confirmation number before you hang up.
Canceling by Live Chat
Open the SiriusXM help page at siriusxm.com and start a chat session. A text agent can process the cancellation without a phone call, which is useful if you’d rather not sit through a verbal pitch. Copy the transcript or at minimum the confirmation number when the chat ends.
Handling the Retention Offer
Expect a discounted rate or a trial extension before the cancellation goes through. The discounts can be steep, so hear the number if price is your only reason for leaving. If you’ve decided, say “I’d like to proceed with cancellation” and repeat it as needed. You don’t owe an explanation.
When Service Ends and What You Get Back
Cancellation takes effect at the end of your current billing cycle. You keep Guardian access through the period you’ve already paid for; SiriusXM doesn’t cut you off the moment you cancel.
Refund eligibility depends on plan type and timing. On a monthly plan, you can request a pro-rated refund if you cancel within seven days of the plan’s start or renewal date. On annual or multi-year plans, the window is thirty days from the start or renewal date. Outside those windows, no refund is issued and you use the service through the end of the paid period. Refunds go back to the original payment method, and SiriusXM’s customer agreement doesn’t guarantee a specific timeframe, so expect at least one full billing cycle before it posts.
What Your Vehicle Loses
Guardian controls the connected features most owners use daily through the app. Once cancellation takes effect, every feature in your paid tier stops working. Subscribers on the Assistance or Assistance + Navigation packages lose:
- Remote vehicle start through the phone app
- Remote door lock and unlock
- Remote horn and lights
- Vehicle Finder GPS location of the parked car
- Send & Go navigation from phone to dash
- Family Drive Alerts and Speed Alerts
If you use the app to warm the car on cold mornings or lock the doors after walking away, you’re back to the key fob. Check the fob battery and know where your physical keys are before service shuts off.
Safety Features That Stay Active
The Safety and Security Package is provided as a separate ten-year trial included with enrollment at no additional cost. It covers SOS Call, Automatic SOS crash detection, Roadside Assistance Call, Theft Alarm Notification, and Stolen Vehicle Assistance. Canceling your paid Assistance or Navigation package does not cancel this safety tier. As long as the vehicle is inside the ten-year ownership window and you’ve enrolled, those emergency features remain active.
The Vehicle Performance Package, which covers monthly health reports and diagnostic alerts, runs on a similar complimentary trial basis. Dropping the paid subscription doesn’t strip the emergency lifeline out of the car.
Transfer Instead of Cancel
If you’re switching vehicles rather than leaving Guardian, transfer the subscription and keep any prepaid time. You can move a plan by signing in online, using live chat, or calling 855-227-6738. Have the Radio ID, ESN, or VIN from the new vehicle ready. You can either remove the old vehicle and shift everything to the new one or link the new vehicle to your existing account. SiriusXM also lets you pause billing through the end of a trial once you link or transfer. Lifetime subscriptions transfer only by phone or live chat, not through the online account center.
Wipe the Vehicle if You’re Selling
Canceling doesn’t clear the Uconnect system. Paired phone contacts, saved navigation destinations, Wi-Fi passwords, and home addresses stay on the car until you factory-reset it. On Uconnect 8.4, press and hold the temperature up and down buttons together for about five seconds, choose the reset to factory settings option when the menu appears, and wait roughly 30 seconds for reboot. Steps vary by Uconnect version, so check your owner’s manual if the layout differs. After the reset, remove the vehicle from your owner app’s digital garage so the account is no longer linked to it.
Confirm the Cancellation Held
About a week after canceling, sign back in and confirm the plan shows as inactive. Watch your bank or credit card statement during the next billing cycle for any new charge. If one appears, your confirmation number is your leverage: contact SiriusXM and request an immediate reversal. If that doesn’t resolve it, file a dispute with your card issuer and include your cancellation documentation.
