We automatically run hundreds of diagnostic and maintenance checks on your vehicle’s key operating systems and deliver a summary report right to your inbox every month. You’ll find information divided into three main areas:
Diagnostic Information provides alerts for your key operating systems (the ones you would see your GM dealer about if there were an issue):
- Engine and Transmission System
- Stabilitrak® Stability Control System
- Air Bag System
- Emissions System
- Antilock Braking System
- OnStar System
Maintenance Information highlights areas that require periodic attention to keep your vehicle running at its best:
- Oil Life and Mileage
- Tire Pressure
Notification Information will let you know if there is a specific recall for your vehicle (so you can easily schedule service with your GM dealer), as well as important OnStar account information.
To ensure you receive your report, be sure to add OnStar Vehicle Diagnostics to your address book.
It’s important to read your report each month because there is always new information about your vehicle. You can track things like your engine and braking systems, oil life and tire pressure — and learn important tips.
- Properly inflated tires help improve fuel economy, and tire rotation helps maximize tire life.
Schedule service at your GM dealer right from your report
- A properly maintained vehicle is a safer vehicle.

- It may not need to be changed every 3,000 miles.
Also check your key systems right from the road. For example, if your check engine light comes on, just push your blue button and an Advisor will run a real-time diagnostics check and provide the results. Relax knowing this service is available whenever you need it.
