The light doesn't pinpoint the exact problem, but it means the Stabilitrak system is actively intervening or has detected something that could lead to loss of control. Possible causes include:
* Low tire pressure: Uneven tire pressure significantly impacts traction.
* Worn tires: Bald or damaged tires reduce grip.
* Faulty wheel speed sensor: These sensors tell the system how fast each wheel is rotating. A bad sensor gives incorrect information, leading to instability warnings.
* Faulty Stabilitrak system components: A malfunction within the Stabilitrak system itself is possible, though less common than the other issues.
* Driving conditions: Extreme weather or aggressive driving can trigger the light even if there's nothing mechanically wrong.
What to do:
1. Check your tire pressure: This is the easiest and most common fix. Inflate tires to the recommended pressure (check the sticker on your driver's side doorjamb).
2. Inspect your tires: Look for significant wear, damage, or uneven wear patterns.
3. Drive cautiously: Avoid aggressive maneuvers until you determine the cause.
4. Have the vehicle diagnosed: If the light remains on after checking tires and driving conditions, take your LeSabre to a mechanic for diagnosis. They can use a scan tool to check for trouble codes that pinpoint the problem.
Ignoring the light is not recommended, as it suggests a potential safety hazard. Addressing the issue promptly will improve your vehicle's handling and safety.
