The so-called "prognostic technology" can predict and notify drivers when certain vehicle components need attention. The components include the battery, starter motor and fuel pump. The "driver assurance" technology will roll out later this year.
Additional vehicle parts and components are expected to be added in future model years.
The service will also roll out on the 2016 Chevrolet Suburban, Corvette, Silverado and Silverado HD models "equipped with certain powertrains," GM said. They will be followed by more Chevrolet vehicles throughout the 2016 model year.
"Using our innovative OnStar 4G LTE connectivity platform, we can actively monitor vehicle component health and notify our customers if covered vehicle components need attention," said Alicia Boler-David, GM senior vice president of Global Connected Customer Experience.
Today, Chevrolet owners with an active OnStar connection can monitor things like tire pressure and oil life via a smartphone app or through a monthly diagnostic e-mail sent from the vehicle. The new service allows customers to check "key data points continuously" without having to wait for a monthly e-mail.
Edmunds says: Think of this as a high-tech security blanket for Chevrolet owners when it comes to keeping track of and servicing their vehicles.
