GM is giving OnStar an AI makeover

General Motors is adding a personal AI assistant to OnStar as part of a broader makeover of the subscription-based connected car service that the U.S. automaker launched 30 years ago.

The company said it will launch a new OnStar mobile app in 2027 that will complement and sync up with its in-car software.

The new OnStar mobile app will replace the current OnStar Guardian app that launched in 2020 as well as vehicle brand apps for Buick, Cadillac, Chevrolet, and GMC.

This tech-centric reboot is unlike other attempts to modernize OnStar, and it notably puts agentic AI at the center.

The OnStar AI Assistant is an in-house effort and one aimed at giving the driver and passengers an interactive and custom experience — and become even more embedded in their daily lives.
