What Causes Water Leakage in the Trunk?

[SanBrady]

Generally, there are two common scenarios that can lead to water leakage in the trunk. The first is a faulty trunk seal strip. To test this, you can use a spray method, but someone must spray water from outside the trunk to observe any leakage. The second, less likely scenario is damage to the negative pressure vent caused by water splashed up by the tires. It's recommended to conduct a thorough inspection. Here are some additional tips: 1. Self-inspection for leakage causes: You can simulate rainwater flowing from the roof using a garden spray bottle to identify potential leakage points. 2. Common leakage causes to check: Inspect whether there are issues with the tail light seals, leaks around the rear windshield rubber strip, cracked seal strips, clogged drainage holes near the seals, or aging and cracked metal panels, among other potential problems.
