1. The vehicle hood is blocked by foreign objects, which makes it impossible to close it tightly. The owner needs to reopen the vehicle hood, take out the foreign objects between the hood and the engine, and then close the engine hood correctly.

2. The way the owner closes the hood of the vehicle is incorrect, resulting in the cable of the hood not returning and the hood lock deforming.

3. The loosening of the locking screw causes the locking machine to drop, the locking machine to shift and the locking hook to break, which leads to the untidiness of the front cover of the automobile.
