[EverlyLee]

The triangular exclamation mark on the dashboard is a general fault indicator light. There are many reasons that can cause the vehicle's general fault indicator light to illuminate, including transmission failure, parking sensor malfunction, vehicle lighting system issues, engine problems, and drivetrain faults. Reasons for the general fault indicator light to illuminate: 1. Transmission failure, which may be caused by overheating transmission, loose transmission gears, or insufficient transmission fluid; 2. Parking sensor malfunction, mostly due to damaged front/rear radar or circuit issues preventing radar recognition; 3. Vehicle lighting system failure, including headlights, turn signals, fog lights, brake lights, and width markers; 4. Engine problems, such as overheating, cylinder misfire, carbon buildup, poor fuel quality, spark plug failure, or fuel system blockage; 5. Drivetrain faults, including ESP stability system failure or ABS anti-skid system malfunction.
