Indicates a malfunction in the traction control system. It is recommended to visit a repair shop as soon as possible for inspection. There are numerous potential causes for the TC light to illuminate, and these issues are not easily handled without professional expertise. They should be addressed by a repair shop.
I've encountered the TC light illuminating in my Buick multiple times, usually indicating a traction control system alert. First, don't panic - I typically try turning off the engine and restarting, as sometimes it's just a temporary glitch. If the light remains on, check whether the wheel speed sensors are covered in mud or have loose connectors, as this affects the system's ability to detect slipping. Most Buick models have a TC button - try pressing it to deactivate and then reactivate the system to see if the light turns off. In daily driving, uneven tire wear can also trigger this light, so I recommend regularly checking tire pressure and condition. If these steps don't work, it could indicate a faulty sensor, wiring issue, or control module problem. In such cases, I promptly visit a dealership to scan for trouble codes using diagnostic equipment, preventing potential driving hazards. Based on experience, most issues can be fixed with relatively minor repairs.
