General Motors Global Connect is GM's built-in connectivity platform for newer vehicles

General Motors Global Connect is the software and service system that lets your GM vehicle communicate with GM's servers and your smartphone. It handles remote features like unlocking your car from your phone, starting the engine remotely, locating your vehicle on a map, and receiving alerts about your car's status. The system runs on a cellular connection built into the vehicle and requires a subscription to access most features.

Every GM vehicle sold since around 2015 has some form of this connectivity hardware, but the features available and whether you pay for them depend on your vehicle's model year, trim level, and which subscription tier you choose. Some basic features like emergency calling may be included for free for a set period, while others require an active paid plan.

Key Takeaways

  • General Motors Global Connect uses a built-in cellular connection to let you control your vehicle remotely through a smartphone app, but most features require a paid subscription.
  • The system includes remote start, remote lock/unlock, vehicle location tracking, and diagnostic alerts, with availability varying by model year and trim level.
  • Your subscription plan determines which features you can use, and GM offers different tiers with different price points and feature sets.
  • The cellular connection in your vehicle is separate from your personal phone plan and is billed directly by GM or through your vehicle's subscription.

What features General Motors Global Connect actually provides

The platform's core features include remote start (warming or cooling your car before you get in), remote lock and unlock (opening or securing doors from your phone), and vehicle location (seeing where your car is on a map). You can also receive notifications when your vehicle is moved, when doors are opened, or when the battery voltage drops.

Diagnostic features let you check your fuel level, tire pressure, oil life, and battery status through the app without opening the hood. Some plans include emergency calling, which connects you to a live operator if your airbags deploy or you press an emergency button in the vehicle. Roadside information is sometimes bundled in, though the coverage and who provides it varies by subscription level.

Not every feature works on every vehicle. Older GM models may have fewer capabilities, and some features depend on your trim level or whether your vehicle has certain equipment installed. Check your vehicle's manual or the GM app to see what's available on your specific car.

How to set up General Motors Global Connect on your vehicle

Setup begins with downloading the GM app (called "OnStar" on older vehicles) to your smartphone. You create a GM account or sign in with an existing one, then add your vehicle to the app using your vehicle identification number (VIN) and other identifying information. The app walks you through pairing your phone with the vehicle's built-in system.

Once paired, the app will show you available subscription plans. Some vehicles come with a trial period of certain features included; others require you to purchase a plan when ready to unlock remote features. You can choose a monthly subscription, an annual plan, or a multi-year plan depending on what GM offers for your vehicle model.

After you purchase a subscription, it typically activates within a few minutes to a few hours. Test a feature like remote lock/unlock to confirm everything is working. If you have trouble, GM's customer service can walk you through troubleshooting or re-pairing your phone.

Subscription plans and what they cost

GM offers multiple subscription tiers, though the exact names, features, and prices change by vehicle model and region. A basic plan might include remote start, lock/unlock, and vehicle location for one price; a higher tier might add roadside information, emergency calling, and more detailed diagnostics. Some plans are sold as monthly subscriptions, while others require an annual commitment.

Pricing varies widely depending on your vehicle's model year and which features you choose. Rather than listing specific dollar amounts (which change frequently and differ by location), contact GM directly or check the GM app for your vehicle to see current pricing. You can also call GM customer service at the number in your owner's manual to ask about plan options before you commit.

If you cancel a subscription, remote features stop working when ready, but your vehicle itself continues to operate normally. You can restart a subscription at any time by purchasing a new plan through the app.

How the cellular connection works and what it costs

Your GM vehicle has a built-in cellular modem that connects to wireless networks independently of your personal phone. This connection is what allows the vehicle to send and receive data even when you're not in the car. The cost of this cellular service is included in your subscription fee—you don't pay GM separately for the data connection itself.

The modem uses a standard cellular network (usually provided through a carrier partnership), so it works wherever that carrier has coverage. If you live or travel in an area with poor cellular coverage, some features may not work reliably. The connection is always active when the vehicle is powered on, which means the vehicle can receive commands and send alerts without you having to do anything.

This is different from your personal phone's data plan. Your phone connects to General Motors Global Connect through the internet (using your own data or WiFi), and then your phone communicates with GM's servers, which send commands to your vehicle's modem. You're not using your phone's cellular data to control the car directly.

Privacy and data security with General Motors Global Connect

When you use General Motors Global Connect, GM collects data about your vehicle's location, how often you drive, fuel consumption, and which features you use. This information is stored on GM's servers and is governed by GM's privacy policy. You should read that policy to understand what data GM collects, how long they keep it, and whether they share it with third parties.

The connection between your phone and your vehicle is encrypted, meaning the commands you send (like "unlock the doors") are scrambled so they can't be intercepted. However, your vehicle's location is visible to anyone who has access to your GM account, so use a strong, unique password for your GM account and enable two-factor authentication if it's available.

If you sell your vehicle, make sure to remove it from your GM account so the new owner can add it to theirs. Leaving your vehicle linked to your account could allow you to see the new owner's location and control their vehicle, which is a security and privacy problem for them.

Troubleshooting common General Motors Global Connect problems

If remote features aren't working, start by checking that your vehicle has an active subscription and that your phone has an internet connection. Open the GM app and try refreshing it. If the app shows your vehicle as offline, your vehicle may be out of cellular coverage or the modem may need to restart—try turning the vehicle off and on again.

If you can't pair your phone with the vehicle, make sure Bluetooth is enabled on both devices and that you're using the latest version of the GM app. Some phones require you to allow location permissions for the app to work. Check your phone's settings and grant the GM app permission to access your location.

If you've recently purchased a used GM vehicle and can't access it through the app, the previous owner may not have removed it from their account. Contact GM customer service with your VIN and proof of ownership, and they can transfer the vehicle to your account or remove it from the previous owner's account so you can add it.

Frequently Asked Questions

Can I use General Motors Global Connect if I don't have a smartphone?

Most remote features require the GM app on a smartphone. However, some vehicles offer a web portal where you can log in from a computer to access certain features. Emergency calling and roadside information may work without a smartphone if they're included in your subscription. Contact GM to ask what options are available for your specific vehicle.

What happens to my General Motors Global Connect if I don't pay the subscription?

Remote features stop working when ready when your subscription expires or is canceled. Your vehicle will continue to run normally—the subscription only controls remote access features. You can restart a subscription at any time by purchasing a new plan through the app.

Can someone else use my General Motors Global Connect to track or control my vehicle?

Only people with access to your GM account can use the app to control or locate your vehicle. If you share your login credentials with someone, they can do anything you can do through the app. Use a strong password and don't share your account. If you suspect unauthorized access, change your password when ready and contact GM customer service.

Does General Motors Global Connect work outside the United States?

General Motors Global Connect works in many countries, but availability and features vary by region. Cellular coverage and subscription plans differ outside the U.S. Check with GM or your vehicle's manual to confirm whether the service is available in the country where you plan to use it.

Will General Motors Global Connect drain my vehicle's battery?

The built-in modem uses very little power when the vehicle is off. However, if you use remote start frequently or leave the vehicle powered on for long periods while parked, you could drain the battery. Modern GM vehicles are designed to manage this, but if you won't be driving for weeks, consider disconnecting the battery or using a trickle charger.
