GM is reshaping OnStar into an AI assistant intended to work across vehicles, phones and cloud services. The system is scheduled to debut in the 2027 Cadillac Lyriq in the coming months, while a unified OnStar app is expected to replace GM’s separate Chevrolet, GMC, Cadillac and Buick apps starting in 2027. Details on compatibility, privacy controls and availability remain incomplete.
General Motors plans to turn OnStar into an AI-powered assistant that can operate across its vehicles, phones and cloud services, while replacing its separate Chevrolet, GMC, Cadillac and Buick apps with one OnStar app. GM says the vehicle system will debut in the 2027 Cadillac Lyriq in the coming months through an over-the-air update, extending the company’s longstanding connected-car service into scheduling, alerts and other tasks.
At a Wednesday event in New York City, GM executives described an assistant designed to use information from a driver’s vehicle and, potentially, personal schedules to respond to changing plans. Chief Product Officer Sterling Anderson said, “The intelligence of OnStar will exist everywhere.” The company’s examples included a vehicle recognizing that a driver will be late for soccer practice, moving a grocery pickup and alerting others to the schedule change. These are examples of the proposed service’s capabilities, not confirmation that every function will be available at launch.
GM plans to introduce the onboard AI in the 2027 Cadillac Lyriq through an over-the-air update in the coming months. Anna Santos, GM’s director of product management for voice and vehicle AI, told The Drive that the company hopes to make the assistant compatible with some earlier models where possible. The report notes that the Lyriq uses a Qualcomm Snapdragon infotainment processor also found in many other GM electric vehicles. GM has also said future versions of the Chevrolet Silverado 1500 and GMC Sierra 1500, among other upcoming models, will get the system.
Beginning in 2027, GM plans to replace its separate brand apps with a single OnStar smartphone app that can bring multiple GM vehicles together. The planned app will offer alerts and guidance informed by vehicle signals, weather, road conditions and route information, and may connect with a user’s calendar. A feature called Connected Cameras is also planned: certain events, such as an aggressive horn honk, could trigger vehicle cameras to record and upload footage to the app, with an alert sent to the owner.
One Assistant Across GM Vehicles
The plan would make OnStar more than a service drivers contact for assistance: GM is positioning it as a software layer across its vehicle brands, with a smartphone app and cloud connections extending beyond the car. For owners of more than one GM vehicle, one app could reduce the need to switch between brand-specific apps. In-car assistance tied to schedules and other personal information could also change how drivers interact with navigation and connected services.
The approach depends on people being willing to share information and trust how it is used. Camera recordings, location, calendar access and vehicle data raise practical privacy questions, even when a feature is intended to help owners. The system’s usefulness will depend on what functions work reliably, which models support them and how much control owners have over data and permissions.

OnStar has operated for 30 years and has more than 12 million subscribers, according to The Drive’s report. The service is known for connected-vehicle assistance, including the option to speak with a person; GM says that human contact will remain available alongside the planned AI features.
The announcement reflects a broader change in GM’s connected services: rather than keeping each vehicle brand’s app separate, the company intends to organize vehicle access and AI assistance under OnStar. The planned rollout is staged, with the Lyriq named as the first model and other vehicles to follow. GM has not said that every existing connected-car feature will be replaced or that all models will receive the new assistant.
“The intelligence of OnStar will exist everywhere.”
— Sterling Anderson, GM chief product officer
Compatibility and Privacy Controls
GM has not provided a definitive list of vehicles that will support the assistant beyond the planned Lyriq launch and its stated plans for future models. The extent of backward compatibility with older vehicles remains uncertain, as do the timing and scope of later rollouts.
Details about privacy settings and data handling also remain limited. Anderson said Connected Cameras footage would be encrypted end-to-end and accessible and shareable only by the owner. GM also said owners will be able to see what information a feature uses, why it needs it and when it is active, and control camera, microphone, location and AI permissions. The settings were not shown at the event, and the company has not supplied further technical details in the source report. It is also unclear which events will trigger recordings or how long footage will be retained.
Lyriq Launch and App Rollout
GM plans to begin the onboard assistant rollout with the 2027 Cadillac Lyriq in the coming months, delivered through an over-the-air update. The company says more models will follow, including future Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles, but has not provided a full schedule or compatibility list.
The company’s next major step is the planned unified OnStar app in 2027, which is expected to take the place of the four brand-specific apps. Owners will need further details on supported vehicles, feature availability, subscription requirements and privacy controls to judge how the new service will work in practice. GM has not given those specifics in the report.
