What does the TC light on the Buick dashboard mean?

Buick dashboard's TC stands for Traction Control System. Here is more information about the Traction Control System (TC): 1. The Traction Control System is a driving assistance system in vehicles that controls the power on the drive wheels. 2. The Traction Control System activates when the drive wheels slip. It limits the engine's power output and brakes the slipping drive wheels to prevent excessive wheel spin. 3. When the Traction Control System is active, the TC light on the dashboard will flash. If it stays lit constantly, it indicates a malfunction, and the vehicle should be inspected at a repair shop as soon as possible.
When I saw the 'TC' displayed on the Buick dashboard, I thought it might indicate that the traction control system is active or in a warning state. I've encountered this before while driving a Buick—the system automatically activates on rainy or icy roads to prevent wheel slip and help stabilize the car. If it flashes briefly, it's likely a normal reminder that it's assisting your driving. However, if it stays lit continuously, it could indicate a sensor fault or an issue with the chassis. I recommend safely pulling over to inspect it first, rather than rushing onto the highway, as losing tire control is dangerous. Regular maintenance should include cleaning the sensors, as Buick's TC system works with ESP (Electronic Stability Program) to enhance safety, but prolonged driving on muddy roads can trigger false alerts.
