Chevrolet wants to change the way cars notify us when something is not working. The GM subsidiary wants to anticipate errors and malfunctions of the car with a first predictive technology in auto industry. 

This enables your vehicle to warn you about a potential maintenance need before it occurs. The technology is similar in concept to that on the Boeing 787, which can send in-flight messages to ground crews alerting them of parts needing inspection before the plane arrives. 

For Chevrolet drivers who opt-in to the service, OnStar Proactive Alerts continually monitors the health of the vehicle’s starter motor, fuel pump and 12volt battery. If anomalies are detected, OnStar will notify drivers to take their vehicle in for service, reducing unexpected repairs.

The service, is available now for OnStar subscribers who own a 2016 Chevy Silverado, Tahoe, Suburban, Corvette and Equinox. Proactive Alerts collects a small batch of data each time the vehicle is started, and monitors it on an ongoing basis. Then, sophisticated systems analyze and refine billions of pieces of data, accumulated across the fleet of vehicles. If the data indicates a particular vehicle’s component is not performing as expected, the system will automatically send the driver a message through an in-vehicle notification, and either an email or text message based on customer preference.


For example, Proactive Alerts can monitor the health of the 12-volt battery. The system is intelligent enough to distinguish between a low state of charge – which can be solved by going for a short drive – and high electrical resistance that could indicate the battery needs replacement.
