Chevrolet is introducing the industry’s first predictive technology, enabling your vehicle to warn you about a potential maintenance need before it occurs.
Our cars have gotten pretty smart over the last 30 years. Carburetors are long gone, being replaced by computer-controlled fuel injection, and just about every car made comes with a built-in diagnostic system to help pinpoint errors in the event of an unexpected failure. Now, Chevy 
In short, Chevy has developed a set of algorithms that allow a car’s computer to monitor certain systems and determine if a failure of that system is imminent. If so, Chevy’s OnStar system will alert the owner via e-mail or text message so that maintenance can be performed before a failure actually occurs. For now, the system only monitors the starter motor, fuel pump, and battery.
According to Chevy, the system is even smart enough to know the difference between a battery in a low state of charge and a high electric resistance – something that could point to a failing battery. Proactive Alerts is available with all OnStar plans, including the five-year basic plan that comes standard with new Chevy vehicles.
