How to Solve the Problem of Water Leakage from the Lavida Sunroof Flowing into the Cabin Along the B-Pillar?

First, you need to turn on the vehicle's ignition and then press the sunroof switch button to open the sunroof. Next, observe the sunroof of the car. You will find drainage outlets on both sides of the sunroof track in the Lavida. Pour water into these drainage outlets to check if the drainage pipes are clear. You need to do this for both sides. If they are blocked, clean them thoroughly.

I also drive a Lavida. Last year, the sunroof leaked, and water flowed into the cabin, which really stressed me out. Later, I found the main issue was clogged drainage holes, causing rainwater to accumulate and flow into the car along the B-pillar. I tried fixing it myself: first, I used thin wire or compressed air to clear the small drainage tubes at the front of the sunroof, where leaves or mud easily clog. After clearing, I flushed water to check if it flowed smoothly. If it still leaked, I checked if the sealing strip had cracks or was aging, causing leaks. Temporary fixes like applying tape can help, but it’s best to replace it. A poorly installed sunroof might also leak—don’t try to fix it yourself if unsure; take it to a repair shop for a full inspection if needed. Regular cleaning of the drainage system is key—check it monthly to avoid water buildup. Don’t forget, there are many electronic components in the car, and leaks could cause short circuits, making things worse. Get it fixed as soon as possible.

Once while driving in the rain, I noticed water leaking from the sunroof, dripping down the B-pillar to the floor, which really startled me. After some research, I found out that for the Lavida, a common cause is clogged drainage pipes or loose connections leading to water backflow. My advice is not to panic. Wait for a clear day and do some troubleshooting yourself: open the car door and check the B-pillar interior for water stains or damage. If present, the drainage outlet might be blocked—use a small tool to clear debris from the sunroof's drainage holes. If the holes are clear but leakage persists, inspect the rubber seals. If they're aged, apply some waterproof adhesive or replace them. Don't delay too long, as prolonged exposure can lead to frame rust. For peace of mind, just take it to a 4S shop—they have tools to detect water leaks accurately, and spending a little now can save you trouble later. Driving safety comes first; water leaks can impair visibility or cause slips, so don't take it lightly.

In the case of water leakage from the Lavida's sunroof into the cabin, my suggestion is to first check if the drainage channels are clear. The front corner drainage holes of the sunroof are often clogged with debris, causing water to overflow towards the B-pillar. Simple cleaning tools or an air gun can resolve most issues. Next, test the waterproofing effectiveness of the sealing strips; if damaged, temporarily secure them with tape. Improper installation may also cause leaks, so adjust the brackets but avoid tampering with hardware if unskilled. If the problem persists, take it to a professional repair shop. The inspection cost is not high, but prolonged leakage can damage the electrical system and interior. Regular maintenance of the sunroof system is crucial—your car deserves care.
