What Causes the Sound of Water Sloshing Inside the Car Door?

[Reese]

It may be due to the drainage holes at the bottom of the door being blocked by mud or sand, preventing rainwater from draining out. As a result, when braking or driving on uneven roads, you may hear the sound of water sloshing inside the door. Here are some related details: 1. Cause: Sometimes, when a car is parked on the roadside, it often gets flyers stuffed into the door. Over time, this can create an invisible gap, allowing rainwater to seep into the door. 2. Risks: If the amount of accumulated water is not too large, it may not be a major issue. However, excessive water accumulation can lead to electrical faults inside the door. Since the drainage holes are blocked by mud or sand, the water cannot drain out. In a sealed space, the water cannot evaporate for a long time, resulting in the sloshing sound. Therefore, it is important to regularly inspect the drainage holes inside the door to prevent them from being clogged.
