Water will leak in if the car door is not closed tightly during rain. Here are some precautions to take after water leakage occurs in the car: Do not turn on electronic devices inside the car: For safety reasons, it is best not to turn on any electronic devices inside the car, such as lights or starting the vehicle, to prevent short circuits caused by water exposure. You can use the key to open the car door. If it is still raining, cover the vehicle with an umbrella or waterproof cloth. Do not use hot air to dry the seats: Wet seats may develop mold. Never use a hot air blower to dry them. If the seats have a heating function, you can use it to speed up water evaporation. After air drying, apply a leather polish cleaner. Avoid soaking the carpet: Do not completely soak the carpet in water for scrubbing, as this can damage the adhesive between the different layers of materials inside the carpet. Additionally, it may take a long time for the carpet to dry completely, affecting its performance and causing dampness inside the car.

I once encountered a situation where the car door wasn't properly closed and leaked during rain. It happened to be heavy rain at that time, and water seeped in through the door gap, soaking a large area of the carpet. The car had a musty smell for several days before it completely dried out. The door itself has rubber sealing strips, but if the door isn't tightly closed, the seals won't compress properly, making it easier for rainwater to flow in near the door sill, especially if the window isn't fully rolled up, which makes it worse. When parking, it's important to develop the habit of pulling the door to confirm it's properly closed, not just relying on the warning sound. If the problem persists, check the door lock or hinges for wear issues. Severe leakage can also damage the interior or electronic equipment, so it needs to be addressed promptly.

From an automotive design perspective, doors not properly closed can indeed leak during rain as they compromise the normal sealing system. The rubber strips on car doors are designed to prevent rainwater intrusion. If not tightly sealed, water can seep through the door gaps and flow onto the carpet or under the floor. Over time, accumulated moisture may lead to rust or mold growth, affecting the interior environment. If you notice leakage, first check if the door is locked securely, and use a towel to absorb the water or seek professional cleaning if necessary. Additionally, similar situations like improperly closed sunroofs can also cause rainwater leakage, so it's important to pay attention to these small details during routine maintenance to avoid costly repairs later.

Leaving your car door not properly closed during rain not only makes the interior wet but can also lead to serious issues. Water seepage causes carpets and floor mats to develop odors, mold growth, and damage to interior materials. In severe cases, it may even cause electrical short circuits, affecting safety systems. The risk is especially high when parked outside, so it's crucial to check that doors are securely closed. If water leakage has already occurred, promptly dry and ventilate the area or seek repairs to prevent rust or corrosion. Developing the habit of double-checking doors before driving is simple yet effective, and it can extend your vehicle's lifespan. Regularly inspect door seals for aging and replace them in time to avoid unexpected troubles.
