What Does a GMC Check Engine Light Mean?

When your GMC check engine light is illuminated, it should always be taken seriously. While it’s true that the problem could be as simple as a loose gas cap, it could also be a sign of serious engine problems. It’s always worth taking your vehicle in for servicing whenever the warning pops up on your dashboard — ignoring this warning could be critical for your engine, and it could require you to visit our GMC service center.

Here are the steps you should take when this symbol makes an unexpected appearance. 

 

Take Immediate Action 

 

As soon as you see a check engine light, it’s always safest to schedule a service appointment at your local GMC dealership. Leaving potential issues unattended can cause more problems in the long run.  

 

For reference, the color of your check engine light will give you an idea of how serious the problem may be. A yellow light means you should take a look at the problem, while a red light means to pull over and stop the car immediately.  

 

As a precaution, you can also try tightening up your gas cap. Doing so may reset the light and avoid a potentially unnecessary trip to the mechanic. 

 

What’s the Next Step? 

 

Scheduling an appointment for vehicle service is the best way to ensure there aren’t any serious issues with your engine. Our Savoy, IL GMC dealership has a team of expert technicians that will be able to diagnose the problem and help you decide the best course of action.  

 

If you find yourself having an increasing number of engine issues, it may be time to consider a new vehicle. Frequent trips to a mechanic for repairs can add up over time. Fortunately, Serra Buick GMC Champaign has an extensive inventory of new and used GMC vehicles to take a look at.
