What to Do When Water Leakage from the Sunroof Causes Water Accumulation?

[LaBrayden]

First, check if the window waterproof strips are aged or loose, and replace them if necessary; inspect whether the door drainage holes are blocked, and clear them if they are. In most cases, water leakage from the sunroof is caused by blocked drainage holes. Sunroof leakage can wet the roof trim panel, and in severe cases, water may even "pour" from the sunroof into the cabin. Sunroof leakage can range from merely wetting the roof trim panel to causing extensive water accumulation inside the cabin. Besides rainwater "pouring" into the car through the sunroof, it can also flow along the A-pillar or C-pillar to beneath the vehicle carpet, forming water accumulation there. If water leakage from the car sunroof causes water accumulation, because the paint thickness in the trunk is relatively thin, water accumulation can easily lead to rust in the trunk, and in severe cases, perforation may occur. To prevent water from entering the trunk, pull the sealing strip to see if it comes off. If it is loose, apply sealant at the joint between the body and the sealing strip and reinstall it. If the trunk sealing strip is aged, replace the trunk sealing strip. If water enters the cabin through the tail light sealing strip, replace the tail light sealing strip or apply special waterproof sealant at the seam between the tail light and the body. Before the rainy season arrives, conduct a detailed inspection of all potential leakage points on the vehicle and replace any aged or poorly sealed components. Taking preventive measures ensures a dry cabin environment during rainy days.
