What to Do If the Car Sunroof Leaks?

First, check if the window waterproof strip is aged or loose, and replace it if necessary; inspect whether the door drainage holes are blocked, and clear them if they are. In most cases, sunroof leaks are caused by clogged sunroof drainage holes. A leaking sunroof can wet the roof trim, and in severe cases, water may even "pour" from the sunroof into the cabin. Here are detailed steps: 1. To prevent water from entering the trunk, pull the sealing strip outward to see if it comes off. If it is loose, apply sealant at the junction between the body and the sealing strip and reinstall it. 2. If the trunk sealing strip is aged, replace it. 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. 3. 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 interior environment during rainy days.
My five-year-old SUV recently started leaking through the sunroof, soaking the carpet every time it rained. As an average car owner, I first checked the drainage holes around the sunroof and carefully cleared clogged leaves and mud with thin steel wire, which stopped the leakage. A friend reminded me that the rubber seals can harden with age, so it's important to wipe the tracks and apply lubricant before each season. Prolonged leaks could lead to mold or rust inside the car—I nearly missed this repair but now I've learned to clean it myself before rainy seasons. If the holes are tightly blocked or the frame is warped, it's safer to avoid forcing it and let professionals handle it. Regular maintenance saves big money by preventing damage to interior electronics—don't let small issues escalate into costly hazards. In short, addressing minor problems early brings peace of mind.
I'm most familiar with DIY repairs. When encountering a sunroof leak, I park on dry ground, open the sunshade, and check the drainage tube inlet for debris. As a DIY enthusiast, I keep a small air canister and soft brush to clean dust and mud, then perform a water test to check the seal. If the leak persists, it's likely a cracked rubber seal—order a matching model online for an easy replacement, but avoid pulling too hard to prevent damage. Monthly simple cleaning of the tracks prevents buildup. Ignoring leaks allows rainwater to soak seats and corrode wiring, making repairs much harder and dozens of times more expensive. I've found uneven frame installation also causes seepage—adjust the mounting screws gently if needed. Long-term water accumulation harms health, so fix it promptly.
