What Causes Water Leakage in a Sedan's Trunk?
2 Answers
Reasons for water leakage in a sedan's trunk: The sealing strip may not be tight enough, or the trunk might be damaged or deformed. Another possible cause is a blocked drainage hole. The sealing strips in a car are consumable items. Being constantly exposed to external air and subjected to frequent use, they are prone to aging and failing to seal properly, which can lead to water leakage. Waterproofing in various parts of a car is ensured by these sealing strips, which are made of rubber material. This rubber material inherently possesses certain strength and hardness, so it generally doesn't deform during use. However, over time, aging is inevitable. When facing trunk leakage, the first step is to identify the source of the water entering the trunk. Once the leak is located, targeted measures should be taken, such as addressing issues like aging or detached sealing strips.
When repairing cars, I often encounter trunk leakage issues. The most common cause is the aging or deformation of the trunk lid's sealing strip. Over time, the rubber cracks, allowing rainwater to seep through the gaps. Another frequent issue is clogged drainage holes. There are small holes at the bottom of the trunk, and when they get blocked by leaves or mud, water can't drain out. Additionally, damaged sealing gaskets on the rear lights or rusted holes in the body seams can let rainwater sneak in. As someone with extensive experience, I recommend checking for leakage traces immediately after rain. If you can't locate the source, you can perform a water test. Don't ignore the issue, as accumulated water can corrode metal parts and soak or mold items inside the car.
