What Causes a Car Fuel Tank Cap to Open Unexpectedly?

[Alivia]

If a car fuel tank cap opens unexpectedly, it is generally due to a malfunction in the fuel tank motor or accidental activation of the fuel tank release button by the driver. Please check whether the fuel tank cap motor is functioning properly. If not, it can be replaced free of charge during the warranty period. Maintenance for the fuel tank is as follows: Drain accumulated water and debris from the fuel tank, and check for oil leaks at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and steam valves, also inspect whether the ventilation holes are clear. The filter screen at the fuel filler inlet should remain intact to prevent impurities from entering the fuel tank during refueling, which could clog the fuel lines. The sealing gasket on the fuel filler cap should also be intact to prevent fuel from spilling out while driving. If the owner wants to check the remaining fuel level in the tank, they can observe the fuel gauge on the right side of the dashboard, which is marked with 'E' and 'F'. When the needle is close to 'E', it indicates that the fuel is running low, while nearing 'F' means the fuel level is sufficient.
