OnStar offers several subscription tiers, each with different features and price points. The basic service tier typically includes emergency calling, roadside assistance, vehicle diagnostics, and access to some mobile app features. Higher subscription levels add services like turn-by-turn navigation, remote vehicle access (such as unlocking doors or locating your vehicle), vehicle health reports, and in-vehicle WiFi connectivity through a separate plan.
The service operates through the cellular connection built into your GM vehicle. When you activate an OnStar subscription, you gain access to a 24/7 call center where trained advisors can provide various services. For example, if your vehicle's check engine light comes on, OnStar can often read your vehicle's diagnostic data and explain what the warning means without requiring a dealer visit.
OnStar subscriptions are available for most General Motors vehicles manufactured from 1996 onward, though features vary based on your vehicle's model year and hardware. Newer vehicles typically have more advanced features available. The service uses your vehicle's built-in cellular modem to communicate with OnStar servers and connect you to advisors.
Different subscription plans suit different driving habits and needs. Some vehicle owners primarily value the emergency services and roadside assistance, while others use remote features like locating their car in a parking lot or checking fuel levels from their phone. Understanding these options helps you determine which plan level, if any, aligns with your actual usage patterns.
Practical takeaway: Before reviewing subscription options, identify which OnStar features you would realistically use. Emergency services and roadside assistance appeal to most drivers, while remote vehicle access and navigation features matter more to drivers who use these functions regularly.
OnStar publishes pricing information for its various subscription tiers, and this information changes periodically. The most current and accurate pricing details are available directly through OnStar's official channels rather than through third-party sources, which may contain outdated information.

You can review OnStar pricing by visiting OnStar.com, where they display subscription tier options and associated costs. The website breaks down pricing by subscription level and shows what features are included with each tier. As of recent updates, OnStar offers several pricing structures: some plans charge monthly recurring fees, while others offer annual prepayment options that may provide discounted rates compared to month-to-month billing.
Many new GM vehicles come with a trial subscription period to OnStar services. These trial periods typically range from three months to one year, depending on the specific vehicle and promotion at the time of purchase. When your trial period ends, OnStar sends communications explaining your subscription options and associated costs. This gives you time to test the service and decide which features matter to you before making a paid subscription decision.
The price guides available through OnStar provide comparisons between different subscription levels, allowing you to see the cost differences and feature additions as you move from basic to premium tiers. Some guides also explain which features are included in no-cost emergency services versus those requiring a paid subscription.
When reviewing pricing information, note that costs may vary slightly by region and vehicle model year. Some older vehicles have access to fewer features, which may be reflected in different pricing structures. Additionally, special promotions occasionally extend trial periods or offer discounted rates for early subscribers.
Practical takeaway: Visit OnStar.com and review the current subscription plans and pricing before your trial period expires. Write down which features you've actually used during your trial period—this real usage data helps you determine whether a paid subscription represents good value for your driving needs.
Most new General Motors vehicles include a complimentary OnStar trial subscription that allows owners to experience the service's features without paying. These trial periods serve as an evaluation window where you can determine which OnStar services you use and whether a paid subscription makes sense for you.

Trial subscription lengths vary based on the promotion active at the time of vehicle purchase. Some trials last three months, others run for six months, and certain promotions extend to one year of free service. Your vehicle's documentation or the OnStar website shows your specific trial end date. OnStar typically sends notifications as your trial period approaches its end date, usually through email and in-vehicle messages.
During your trial period, you have access to the full range of features available in OnStar's top subscription tier. This means you can test emergency calling, roadside assistance, turn-by-turn navigation, remote vehicle features, vehicle diagnostics, and other available functions. Taking advantage of this testing period helps you understand which services you actually use versus which ones sound useful but rarely get used.
Many vehicle owners discover that they primarily use only specific OnStar features. For example, someone might use emergency calling and roadside assistance regularly but never use the turn-by-turn navigation because they prefer their smartphone's maps app. Others find the remote vehicle access feature (like locking doors or locating their car) addresses a real need in their daily life. The trial period lets you gather this personal usage data.
If you decide you want to continue OnStar services after your trial ends, you can select a subscription plan that matches your needs. You don't have to choose the premium tier if only basic features appeal to you. Conversely, if you find you use many features, the premium subscription provides better value than paying month-to-month.
Practical takeaway: During your OnStar trial period, use the features you think you'll want in a paid subscription. Keep a simple note of which services you actually accessed. When your trial ends, this record shows you whether the subscription cost provides genuine value based on your real behavior.
OnStar structures its offerings in subscription tiers that provide progressively more features at higher price points. Understanding the differences between tiers helps you select one that matches your driving style and budget without overpaying for unused features.

The basic tier typically focuses on safety and essential vehicle information. This level usually includes emergency calling (OnStar advisors can contact emergency services on your behalf if you're unable to), roadside assistance (towing, lockout services, fuel delivery, etc.), and vehicle diagnostics that alert you to maintenance needs. Many drivers find these features sufficient if their primary concern is safety and knowing when their vehicle needs service.
Mid-tier subscriptions add navigation features, including turn-by-turn directions and real-time traffic information. They also expand vehicle diagnostics to provide more detailed health reports and may include limited remote access features. This tier appeals to drivers who want navigation through OnStar rather than using a smartphone app, or who value more detailed vehicle information.
Premium subscriptions include all previous features plus full remote vehicle access. This might include remotely locking or unlocking doors, locating your vehicle, checking fuel level, checking door lock status, and starting your engine remotely (if your vehicle supports it). Premium plans often include vehicle WiFi connectivity options and access to additional in-vehicle services.
Some specialty services operate separately from the main subscription tiers. For example, vehicle WiFi connectivity through OnStar's partnership with AT&T is typically a separate subscription that adds to your OnStar costs. Similarly, certain advanced features in newer vehicles may have distinct pricing.
The choice between tiers depends on your specific situation. A driver with a short commute who rarely travels to unfamiliar locations may not value navigation features. A parent of teenage drivers might prioritize the family features in higher tiers that allow monitoring vehicle use. Someone with an older vehicle might find fewer premium features are available regardless of tier selection.
Practical takeaway: List the specific features that matter to your actual driving needs, then select the subscription tier that includes those features without paying extra for capabilities you won't use. Review the features included in each tier on OnStar's website to match your specific requirements.
