What Happened
For 30 years, OnStar has kept people connected and able to get help on the road. GM says AI is reshaping how people live, work and make decisions, and it is transforming OnStar into a connected intelligence layer intended to make every drive more personal and enjoyable while preserving the timely assistance customers trust. By combining real-time vehicle data, context and connected services, OnStar is meant to deliver more personalized, proactive experiences across the vehicle, the OnStar mobile app and GM Fleet.
The new OnStar AI Assistant is designed to let drivers get things done without taking their attention off the road: the driver says “Hey OnStar,” then states what they need. The assistant is built around the vehicle, its context and authoritative GM knowledge, combining conversation with vehicle understanding and operating under the customer’s permissions and privacy controls. GM says that integration allows support tailored to the vehicle and lets the Assistant complete complex tasks that general-purpose assistants cannot, and when a question calls for human help it can connect the user with an OnStar Advisor. The native assistant will debut in the 2027 Cadillac LYRIQ in the coming months through an over-the-air update, with additional GM vehicles to follow.
- Make adjustments without reaching for a screen: change the temperature, turn on dome lights, open the glove box or charge port, and manage other vehicle functions with natural voice commands.
- Report what the vehicle is doing: give real-time updates on tire pressure, range or charging status.
- Answer questions about the exact vehicle: explain one-pedal driving, lane keep assist or any specific feature for that model.
- Reach beyond the vehicle: soon bring answers and support to a new OnStar app, keeping drivers connected to their vehicle, their family and the world around them.
Starting in 2027, the intelligence that powers GM vehicles will extend into a new OnStar app, creating one integrated AI-powered experience linking drivers to their vehicles, the people and places that matter, and the world around them. With Connected Cameras, a detected trigger such as an aggressive horn honk causes the onboard cameras to capture the event, upload it securely to the OnStar app and send the customer an alert so they can see what happened. OnStar Family is meant to connect the people, vehicles and routines that matter most, letting family members share destinations, coordinate pickups, oversee other vehicles and receive relevant safety or community alerts. By combining vehicle signals, weather, road conditions and route information, OnStar also aims to provide timely safety alerts and guidance.
- OnStar Guardian plus separate Buick, Cadillac, Chevrolet and GMC mobile apps
- One new OnStar mobile app replacing all of them, for a unified experience across vehicles and devices
- Features are only activated if customers choose to use them, and they can be switched off at any time.
- Customers can see what information a feature uses, why it is needed, when it is active and how it is handled.
- Camera, microphone, location and AI permissions can be managed with clear indicators and simple settings.
- Customers decide what data is shared.
- Recordings have time limits and are encrypted, and GM says it cannot access Connected Camera recordings.
GM says the same connected intelligence behind the everyday driving features also helps businesses run their fleets more efficiently. OnStar Fleet Intelligence brings vehicle data and connected services together so fleet managers can spot issues sooner, reduce downtime and manage costs across vehicle health, maintenance, and fuel and energy use. Built into the platform, the OnStar Fleet AI Assistant turns that data into practical guidance, letting fleet managers ask questions in natural language to identify trends, improve vehicle utilization and make more proactive decisions.
Previously from General Motors
In September 2026, GM launched OnStar Fleet Intelligence, described as a single-account platform that pulls vehicle data and connected services into one dashboard to help fleet operators cut costs and reduce downtime.

Why this matters
The change matters most to people who own or buy GM vehicles: a factory-built assistant that can explain warnings, check range and adjust cabin settings by voice goes beyond a general-purpose chatbot, and GM is tying it to privacy controls and a live OnStar Advisor. Fleet managers get a similar natural-language tool inside OnStar Fleet Intelligence.
