How to use your myBuick mobile app

Getting started

1. Download the myBuick app from the Apple App Store®* or on Google Play*. 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.

  • You can also text [“Buick,” “Cadillac,” “Chevrolet” or “GMC”] to 56000* to receive a link to download the mobile app.
  • If you have multiple vehicles across different brands, you can download any app (myBuick, myCadillac, myChevrolet or myGMC). All vehicles on your account will show up in the Account menu of the app you’re using. Use the product selector to scroll between them and select a vehicle to view.

2. Create an account or sign in to the 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. Plus, be sure to be on the lookout for even more future updates to your mobile app.

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 GM RewardsTM* your GM Account (chevrolet.com, buick.com, gmc.com or cadillac.com), 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.

Which app should I download if I have more than one vehicle on my account?

If you own multiple vehicles across brands, you can download any app you prefer. You’ll be able to manage all vehicles on the account using the Product Selector in the Account menu. Tap the initials in the top-right corner of the mobile app’s Home screen to access the Product Selector and other account features. 

Why isn’t my vehicle showing up in the 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 my recent oil change not showing up in the oil life status on my dashboard and app?

This signifies the oil life monitor system was not reset, and you must manually reset it. For detailed instructions on how to do this, refer to the Owner's Manual by tapping Help at the top-right corner of your user profile screen in your app. Help topics will display at the bottom of the screen. 

If other information in the app seems inaccurate: 

  1. Get in your vehicle and start it. 
  2. Use the dashboard controls (usually on the steering wheel) to navigate to the vehicle information menu. 
  3. There, you can check the tire pressure, oil life or fuel/battery level and/or view any warning lights shown in the driver display.

Why is the app slow or crashing?

If the 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.
