GM Holdings LLC OnStar Launched in 1996, OnStar is a wholly owned subsidiary of GM Holdings LLC ("GM") and offers emergency, security and navigation services in Chevrolet, Buick, GMC and Cadillac models. OnStar offers a range of subscription services such as Automatic Crash Response, Emergency Services and Stolen Vehicle Assistance.

OnStar was initially a Dealer-installed device offered in several 1997 Cadillac models. We eventually perfected the technology with the built-in system Members use today.

It's a question we hear a lot - “can OnStar locate my car?” We sure can. Once law enforcement confirms your vehicle has been stolen, our Advisors use GPS to help authorities find your vehicle.

In the case of the mandatory OnStar option, a GMC spokesperson told the Detroit Free Press that the company chose to make the connected services standard because it's "more convenient for our customers and provides a more seamless onboarding experience."
