When warning lights and messages appear on your vehicle’s dashboard, they often indicate a problem with one or more systems. While many warning lights are standard across different vehicles, there are some that are specific to certain makes and models. One such message is the “service StabiliTrak” message found in General Motors (GM) and Chevrolet vehicles.
A Closer Look at Chevy and GM’s StabiliTrak Feature
Before we dive into the meaning behind the service StabiliTrak message, let’s take a closer look at how this feature works. StabiliTrak is GM’s enhanced version of the electronic stability control (ESC) system. Both systems rely on steering inputs to restore vehicle stability when the driver is unable to control the vehicle.

The StabiliTrak feature primarily operates under two conditions: oversteering and understeering. Oversteering occurs when the vehicle is driven on a curve at high speeds, which may cause the vehicle to spin out of control. In such cases, StabiliTrak or the ESC system will engage one of the brakes, usually the right front brake, to correct the vehicle’s path. On the other hand, understeering occurs when the vehicle loses traction while making a turn. The ESC system or StabiliTrak will engage the right rear brakes to restore stability.

StabiliTrak is designed to function in low-traction conditions, such as slippery roads or snow-filled streets. It uses the steering wheel position sensor to check if the steering wheel and tires are aligned with the vehicle’s intended path. If the system detects that the vehicle is not following its intended path, StabiliTrak will reduce engine power and apply brakes to individual wheels to help the driver regain control of the steering wheel.
What Does the Service StabiliTrak Message Mean?
When you see the service StabiliTrak message illuminated, it means that the system is likely disabled until the underlying issue is resolved. In other words, you won’t receive assistance from StabiliTrak when driving under low-traction conditions. Several reasons can trigger this message, including sensor, wiring, or control module issues; low brake fluid; a faulty throttle position sensor or throttle body assembly; a faulty steering wheel position sensor; a malfunctioning anti-lock braking system (ABS); forcefully disabling the StabiliTrak feature; or lifter failure.
Can You Drive With a Service StabiliTrak Message on Your Dash?
Yes, you can still drive your GM or Chevy vehicle with the service StabiliTrak message displayed. However, it’s important to remember that warning messages appear for a reason, and it’s not advisable to ignore them for too long. A disabled StabiliTrak system increases the risk of losing control when your vehicle loses traction, so it’s essential to address the problem as soon as possible.

If your vehicle’s StabiliTrak system is disabled, you might notice the following changes:
- Reduced Stability: StabiliTrak helps drivers maintain vehicle control, so its absence may make it difficult to keep your car on a straight path and result in increased body rolls when turning.
- Frequent Activation of the ABS: The ABS might activate more frequently than usual if the StabiliTrak system is disabled. This is typically characterized by a pulsating brake pedal. Faulty front wheel bearings can also cause the ABS system to activate whenever the wheel is turned.
- Performance Issues: A disabled StabiliTrak system can lead to decreased engine performance, although this is more of a safety precaution than an engine problem. You might also experience difficulty in turning or steering without StabiliTrak.
How to Reset the Service StabiliTrak Light
Before attempting to reset the service StabiliTrak light, ensure that all system issues have been resolved. Resetting the service message without addressing the problem will only cause the warning to reappear. If you’re confident that the problem has been fixed and the warning light is still on your dash, follow these steps to reset the message without using a scan tool:
- Shut off the engine and disconnect the battery. Start by disconnecting the negative terminal.
- Wait for a few minutes to allow any residual electrical charge to dissipate before reconnecting the battery.
- Upon starting the engine, some systems will perform a self-check, which should turn off the service StabiliTrak light.
Common Issues With StabiliTrak
Despite being known as one of the most efficient ESC systems, GM’s StabiliTrak has faced some controversies regarding its reliability. In a class-action lawsuit filed against General Motors, owners alleged that the StabiliTrak system in several models was faulty, causing their vehicles to exhibit various issues. However, the courts found that the majority of complaints did not point to a faulty StabiliTrak system. There have also been instances of the StabiliTrak message appearing on vehicle dashes for no apparent reason.
Overall, understanding the meaning behind the service StabiliTrak message and addressing any underlying issues promptly will help ensure your safety on the road. For more information about Eireview and the latest technology trends, visit Eireview.
