LIKE A PHYSICAL EXAM FOR YOUR VEHICLE
Each month, you can receive a report that includes status alerts for key vehicle operating systems such as the engine, transmission, antilock brakes and air bags. Everything you need to know is in one handy email.
To stay updated on your vehicle in real time, sign up for Diagnostic Alerts. Choose to receive a text or email, and when there’s an issue that needs your attention, you’ll know right away.
Advanced Diagnostics delivers peace of mind knowing that your vehicle is ready for the road ahead. But did you know it can also help you save money?
TIRE PRESSURE ALERTS COULD HELP SAVE MONEY AND THE ENVIRONMENT
Knowing when tire pressure is low can help you avoid more than an inconvenient flat. By keeping tires properly inflated, you can get better fuel economy and also help the environment. By following tire pressure alerts in the monthly report, Subscribers could collectively save millions of gallons of fuel per month.
SAVE OIL AND TIME, TOO
The Advanced Diagnostics reports let you know exactly when it’s time for an oil change. The GM Oil Life System monitors a vehicle’s oil and tells when to change it based on how you drive.
By following oil life alerts in the monthly email, fewer oil changes could be required every year, potentially saving more than $30 per Member. Among U.S. Subscribers, that’s more than $160 million saved per year on oil changes. And our Members could collectively conserve millions of quarts of oil per year by following the oil life alerts in their emails.
STAY AHEAD OF MAINTENANCE WITH PROACTIVE ALERTS
Knowing about potential issues before they become a problem helps make vehicle ownership easier than ever. With Proactive Alerts, you’ll receive a text or email that notifies you about upcoming repairs, such as a battery that’s losing its charge. This can help you avoid the headache of unexpected repairs — and potentially ending up stranded.
