Download on the Google Play Store

Getting started

1. Download the myBuick mobile app from the Apple App Store®* or the Google Play* store. If you already have it, you can check for any available updates to the app by searching for “myBuick” in the App Store or Google Play.

2. Create an account or sign in to app using your GM account email and password (the same email address you gave your dealer when you bought the vehicle).

Note: Signing in with an email account already registered with an OnStar® account allows your vehicle to sync with the app and provides access to subscription-based app features. Learn more about how to link your OnStar Account with your brand account here.

3. If you’re a new user or you’ve updated the app, you’ll be presented with a multi-factor authentication process to verify your identity.

Make sure you keep your app updated to the latest version to see what’s new. Be sure to be on the lookout for even more future updates to your mobile app.

Using the app's home screen

The app’s home screen simplifies your ownership experience with features that help keep you informed and in control. The features, functionality and design of the Home screen will depend on your service plan and how your vehicle is equipped.

Note: If your vehicle is not connected to services, your Home screen will work differently.

Tap the Account Menu (which appears as your initials) in the upper right corner to access your Account information.
If you have more than one vehicle, go to the Account menu to change which vehicle you’re viewing or add a new vehicle.
Along the top of the home screen, you’ll see three tabs:

My Vehicle: Find essential remote commands and quick-view widgets, including Vehicle Status and EV Charge Status, if your plan and vehicle support them.
Controls: Access additional remote commands and customizable Vehicle Settings.
Help Center: Tap to schedule service, get Roadside Assistance, read your Owner’s Manual or call OnStar® for help.

Along the bottom of the home screen, you’ll see icons to return home, access map and EV Navigation features or more app features.

Remote commands

If your vehicle and service plan support remote commands* (e.g., remote start/stop), you’ll find the essential controls right on the app’s home screen.

Tap and hold one of the remote command icons to start a request. The app will tell you to keep holding until the request is complete. It may take a few seconds.
For other remote commands not listed on the home screen, go to the Controls tab. You can also tap “View More” to see more options.

For your security, please don’t include personal info such as phone number, address or credit card details.

Q&As

What email address should I use to sign in?

You must use the same email address you provided the dealer when you bought your vehicle, or that you provided the Advisor during your Welcome Call. That means you may have to create a new account if you do not already have a profile using that email address.

If you already have a sign-in (email address and password) with OnStar or other GM services, such as My GM Rewards, your GM Account (chevrolet.com, buick.com, gmc.com or cadillac.com; previously Owner Center), GM Family First, the OnStar Guardian app, etc., you should use that to sign in.

If you don’t use the correct email address, your account will not link to your new vehicle or services.

Why isn’t my vehicle showing up in the mobile app?

If your correct vehicle isn’t appearing in the app, it is likely an account linking issue. This may be because your account is linked to an old email or you didn’t link your account when you set up your profile. It could also be because you recently made changes to your OnStar account (such as renewing or upgrading, consolidating multiple accounts, etc.) and the changes have not yet been synced. You can try logging out of and back in to the app. If you’re still having trouble, call an OnStar Advisor at (877) 558-8352 for help fixing this issue.

Why is the mobile app slow or crashing?

If the mobile app is running slowly or crashing, here are a few things you can try:

Force-close the app, manually log out and log back in, check for the correct delivery system and then ensure your correct credentials are entered.
Uninstall the app and then reinstall it on your phone.
Restart your phone.
Check to see if your phone’s Operating System is up to date by going to your phone’s settings. If it isn’t, install the latest update.
Clear your phone’s cache, which might help improve the device’s speed. You can contact your device manufacturer to learn how to do this.
Turn off “Power Saving Mode/Low Power Mode,” if it’s enabled on your phone. Power saving mode may disable or delay certain app permissions and functions from working properly to conserve battery.

Why do I have to hold the button in the app to issue a remote command?

The approximately two-second hold is an industry standard designed to help avoid accidental presses of the button, so you don’t unintentionally start or unlock your vehicle. When you press the icon, the app will remind you to “Keep Holding” until the command is issued. When the command is successful, the button will say “Sent.”

On some newer models, each time the app is opened, remote commands may take longer than other models to complete (up to 60 seconds, in some cases). The app will notify you once the command is successful. Any additional remote commands requested in that same session should complete more quickly.

How do I remove a vehicle in my mobile app?

Open the mobile app and sign in.
Select the Account anchor icon, which looks like a circle with initials.
Select Manage my Products.
Select the vehicle you want to remove.
Select Remove and the reason for removing.

Important: If the above process doesn’t work, in some cases, you may need to contact an Advisor for help removing your vehicle from the mobile app. Call (877) 558-8352 for assistance.

How do I add a vehicle in my mobile app?

Open the mobile app and sign in.
Select the Account anchor icon, which looks like a circle with initials.
Select Add Product, then Add Vehicle.
Enter the VIN and other requested vehicle details, then select Done.

Important: If the above process doesn’t work, in some cases, you may need to contact an Advisor for help adding your vehicle to the mobile app. This would happen if, for example, your vehicle is not activated or if it’s linked to a different account. Call (877) 558-8352 for assistance.
