Would you trust an AI assistant in your car to record and share your data?

General Motors announced an AI-based intelligence layer for its OnStar in-vehicle assistant, combining real-time vehicle-specific data with context and connected services. The AI-powered OnStar assistant will debut in the 2027 Cadillac Lyriq via over-the-air update.

Why it matters

GM says the new version addresses long-standing consumer privacy concerns through analytics data streams and opt-out policies. Features are activated only if customers choose to use them and can be switched off at any time, giving U.S. drivers control over how the system operates.

OnStar, first launched in 1996 for select models, is being upgraded with generative AI features that connect to vehicle data. The rollout timing for additional GM models has not been detailed.

The players

General Motors

General Motors is a Detroit-based automaker that owns the Cadillac, Chevrolet, Buick, and GMC brands and has been expanding its electric vehicle lineup.

The details

The new OnStar version supports connected cameras that automatically record triggered incidents, with recordings encrypted, time-limited, and inaccessible to GM. The AI-powered OnStar mobile app will replace the OnStar Guardian app and the Buick, Cadillac, Chevrolet, and GMC companion apps.

Roadmap

The AI upgrade extends OnStar, a connected-services platform GM has offered since 1996, into the generative AI era. It positions GM's electric vehicle lineup alongside rival automakers racing to add conversational assistants to their cars.

Drivers who choose to use the AI features can check real-time EV range and map charging stops, or connect with a human OnStar Advisor. OnStar Family also lets family members share destinations and coordinate pickups, with all features switchable off at any time.

The takeaway

Drivers who want the AI features can turn them on, and those who prefer privacy can keep them off. Checking camera and data settings in the OnStar app is a practical first step after the 2027 rollout.
