OnStar recently sent its 100,000,000th OnStar Vehicle Diagnostics e-mail, marking a significant milestone for a service that has the ability to save drivers millions of dollars in automotive maintenance costs by providing alerts for the vehicle’s key operating systems including the safety systems.

By following the tire pressure alerts in the e-mails and keeping their vehicles’ tires properly inflated, subscribers can save an average of $70 each per year in fuel costs. This adds up to a total of more than $30 million per month and more than $350 million annually for OnStar’s complete subscriber base.
