What does an exclamation mark on an electric vehicle mean?

This indicates a power supply failure in the electric vehicle. This warning light usually illuminates along with other fault lights, indicating a power supply issue. If this light comes on alone, it means there is a communication failure in the system bus. Causes of motor failure: The main reasons for motor failure are either a damaged motor Hall element or a faulty motor bearing. A damaged motor Hall element typically manifests as the electric vehicle not moving, having weak acceleration, shaking, making loud noises, or requiring a push to start. A faulty motor bearing usually causes loud abnormal noises from the motor, and in severe cases, it can lock up the motor, cutting off power to the entire vehicle. Methods to handle brake power-off faults: Brake power-off faults mainly manifest as a faulty brake power-off switch, the vehicle not moving when the brake is not released, or an open circuit in the brake power-off line. If the power-off fault is caused by a faulty brake power-off switch, it can be resolved by polishing the contacts and adjusting the spring plate. If this doesn't work, replacement is necessary. If the power-off fault is caused by the vehicle not moving when the brake is not released, the brake pads or the entire brake assembly should be replaced. If the power-off fault is due to an open circuit in the brake power-off line, replacing the line is the solution.

I also encountered the exclamation mark on the dashboard last time, which scared me into pulling over immediately. This warning symbol usually indicates a minor issue detected by the vehicle, possibly an abnormality in the charging system, such as an unsecured charging port or poor contact with the charging gun. Try unplugging and reinserting it. If it lights up while driving, pay attention as it could indicate low tire pressure, a brake system warning, or an issue with the electronic stability system. Immediately reduce speed and check the dashboard for specific alert messages. Never ignore it and continue driving, especially if it's a red exclamation mark, which requires immediate action. Contacting the manufacturer's customer service directly is the most reliable option, as they can access specific fault codes from their backend.

The exclamation mark light in electric vehicles is quite common, I've encountered it four or five times. The most likely cause is a charging fault, such as the charging gun not being properly inserted or a communication interruption with the charging station. If there's an issue with tire pressure or insufficient brake fluid, it can also trigger this alarm. High-voltage battery overheating or BMS system abnormalities will similarly display the exclamation mark. It's recommended to stop the car, turn it off, wait for two minutes, and then restart it—temporary faults might disappear. If the light persists, check the user manual for the corresponding symbol explanation, as different vehicle models have varying positions and colors representing different severity levels. Don't attempt to dismantle high-voltage components yourself; the risk is too high.

This exclamation mark indicates that the vehicle has detected an abnormal condition. A yellow symbol usually signals issues that require attention, such as an overheated fast-charging port or insufficient washer fluid. A red symbol is far more serious, potentially involving power battery failure or high-voltage system insulation failure. When encountered, first slow down and pull over to a safe area, then check the central control screen for specific fault descriptions. If unsure how to proceed, don't take risks—call the 4S store's after-sales service, send them a photo of the dashboard, and they'll advise whether it's safe to continue driving. It's also crucial to have technicians check historical fault records with a diagnostic tool during regular maintenance.
