If you own or drive a modern GM car, the automaker’s StabiliTrak safety system keeps an eye on you and the road. Since 2010, the system has been standard on all non-commercial GM vehicles.

Stabilitrak is a type of stability control system designed to automatically read and correct any discrepancies between the driver’s desired direction of travel and what the car or truck (or minivan, etc.) does in real life. There is a difference between stability control and traction control, but the former uses the latter’s characteristics to operate.

When you’re driving on icy or wet roads or around tight curves, StabiliTrak helps steer your vehicle in the right direction. It analyzes driver input and road conditions through a series of sensors, and controls braking and engine power to help maintain control. On GM models, StabiliTrak includes features that help with other driving scenarios, such as hill start assist to prevent unwanted body roll and trailer sway control.

So, is it a problem when the “Service StabilTrak” message appears on your dashboard display? Or can you ignore it until your next service or oil change? Let’s look at some of the possible reasons why this message appears and what it means for your vehicle.

It’s not always obvious why the “Service StabiliTrak” message is displayed based on vehicle noise or responsiveness. Since StabiliTrak is connected to multiple systems and sensors, such as traction control and ABS, the warning can indicate issues ranging from faulty sensors for wheel speed or tire pressure to throttle or steering wheel position. It could also include engine misfires, the brake switch, faulty or disconnected wiring, or even low brake fluid.

What’s your next step when you see “Service StabiliTrak”? The vehicle is usually still drivable unless other common dashboard warning lights, like “Check Engine,” are illuminated. If you have a check engine light on, you can use a code reader tool (or go to an auto parts store that scans engine codes) and see if an issue like a misfire triggered the warning.

When the StabiliTrak (traction control) light comes on and stays on along with the “Service StabiliTrak” message, it likely means that the system is not working and can’t help you if you lose traction. Additionally, it can cause your brake pedal to pulsate or make driving a little harder. If you’re not sure what triggered the warning, have your GM vehicle checked by a mechanic who is familiar with the StabiliTrak system. It could be a minor issue or something that prevents the system from saving your life.
