What are the reasons for water leakage in a car's trunk?
2 Answers
The reasons for water leakage in a car's trunk are: 1. Poor sealing of the trunk's gasket or tail light seal; 2. The sunroof is not properly closed or the rubber seal has aged; 3. Clogged drainage pipes. The trunk serves as a storage compartment for miscellaneous items in a car, enhancing life convenience. Inside the trunk, you can typically find a spare tire, vehicle emergency kit, onboard tool kit, warning triangle, fire extinguisher, and the emergency fuel tank release cable. Maintenance methods for the trunk: 1. When cleaning, use a brush to remove dirt, including the edges and troughs of the trunk, followed by odor treatment after cleaning; 2. Use separate storage bags to organize items systematically; 3. Lay a trunk mat to prevent dirt or liquids from entering and corroding the trunk surface, while also preventing items inside from sliding, thereby reducing the risk of contamination or damage.
As an enthusiast who frequently assists with car repairs, I've encountered numerous cases of water leakage in the trunk, with various causes: The most common is aging or damaged sealing strips. Those rubber strips can harden, crack, or deform after a few years, allowing rainwater to seep through the gaps. Another issue is clogged drainage holes—some cars have sunroof drainage tubes leading near the trunk, and if blocked by leaves or debris, water can backflow into the trunk. Additionally, poor sealing around the taillight assembly or malfunctioning vents can also cause leaks. I recommend car owners check the elasticity of the sealing strips before the rainy season by pressing them to ensure a tight fit, and clear any debris from the drainage holes under the trunk. Untreated water ingress can lead to rust or mold in the car's interior components, compromising safety, so having it fixed by a professional shop is a hassle-free solution. Also, avoid blasting high-pressure water at the trunk seams during car washes to prevent premature aging of the seals—this maintenance habit can prevent issues before they arise.
