Why is the car trunk leaking water?
2 Answers
The most common reasons for trunk water leakage are: 1. Aging rubber components: The sealing strips around the sunroof and trunk play a crucial role in isolating rainwater. When these rubber strips age, water leakage becomes likely; 2. Damaged seals: Vehicle waterproofing relies on rubber seals throughout the body. These seals have certain strength and hardness, maintaining shape under pressure. However, prolonged exposure to air causes natural aging, and frequent use leads to wear. Damaged seals allow water infiltration.
A leaking trunk is really annoying. I think it’s mostly due to the aging of the sealing strip—after prolonged exposure to wind and sun, the rubber cracks and loses its seal. The drainage holes are also crucial; if they’re clogged with dirt or leaves, rainwater can seep in. Another possibility is that frequent opening and closing of the trunk lid may have misaligned it, creating gaps that let water in. To fix it, first check if the sealing strip is intact—feel for any damage. Then, inspect the drainage holes at the bottom of the trunk to see if they’re clear; it’s better if you can clean them yourself. If the problem is severe and left unrepaired, the trunk will stay damp, leading to mold and a musty smell. The seats may even absorb moisture, and driving in summer with that lingering odor is just unbearable. Act quickly—either inspect it yourself or get someone who knows cars to help. Don’t delay until it becomes a bigger issue.
