What does a triangle exclamation mark displayed on the car mean?

A triangle exclamation mark displayed on the car is a general fault indicator light. The reasons for this light turning on include: 1. Overheating of the dry dual-clutch transmission; 2. Fuel cut-off system intervention or malfunction; 3. Parking sensor malfunction; 4. Exterior bulb failure; 5. Engine oil pressure sensor malfunction; 6. Traction control system warning or malfunction. In addition to the triangle exclamation mark indicator, other dashboard indicators with an exclamation mark include the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and windshield wiper fault indicator. Whenever any warning light with an exclamation mark illuminates, it indicates a problem with the corresponding component of the car, and immediate inspection and repair are necessary.
I've been driving for over 20 years, and this triangular exclamation warning light is quite common—it's like the vehicle's general alarm system. It could indicate low tire pressure; last time I was on the highway, the tire pressure sensor triggered an alert. It might also signal transmission issues, especially in Volkswagen DSG models, which are prone to such problems. Another time, I discovered it was because the electronic parking brake wasn't fully released, which was both frustrating and amusing. The most critical scenario is a brake system failure, where a red brake warning light will also illuminate on the dashboard. My advice is to pull over immediately when you see this light, check the brake responsiveness and tire condition—safety always comes first.
