What Causes the Sunroof Leakage in the Mistra?

The reasons for sunroof leakage in the Mistra are as follows: 1. Prolonged exposure to intense sunlight can cause the sealing strip to age and crack: Factors such as never opening the sunroof, frequent exposure to strong sunlight, forcibly opening the sunroof when it's frozen in winter, or using low-quality car wash liquids can lead to the aging and cracking of the sealing strip; 2. The sunroof and sealing strip are not tightly sealed: If there is a gap between the sunroof and the sealing strip, it will naturally cause leakage; 3. The drainage holes of the sunroof are blocked, causing rainwater to accumulate in the drainage channel: When the drainage holes are clogged, a large amount of rainwater can accumulate in the sunroof's drainage channel, leading to leakage over time; 4. The drainage pipe or its joints are broken: This situation requires professional repair at a service center to disassemble and reassemble the interior trim panel.

I also encountered the issue of a leaking sunroof on my Hyundai Mistra before, mainly caused by clogged drainage holes or aging seals. The sunroof is designed with tiny drainage holes around it, which can easily get blocked by leaves and dust, preventing rainwater from draining properly and causing it to drip into the car. Additionally, the sealing rubber can deform or crack over time due to exposure to wind and sun, allowing water to seep in. If left unrepaired, accumulated water can damage the interior, cause mold, or even affect electronic components. It's recommended to clean the drainage holes once a year, flushing them with a soft hose, or have them inspected at a 4S shop to prevent minor issues from becoming major problems. Also, try not to park under trees to reduce the risk of clogging. In short, timely action is crucial—don’t let a small leak turn into a big headache.

Sunroof leaks are common in the Mistra due to drainage system failure or frame deformation. The narrow drainage tubes are prone to clogging, causing water backup when dust accumulates; if the frame has been impacted or loosens over time, rainwater can seep in. Having driven one for years, I've found prevention is key: regularly clean the roof drainage holes with a vacuum and inspect the seals annually for cracks. If a leak occurs, use a towel to absorb water as a temporary measure to prevent mold in the interior. Worse, water entering the electrical system can cause short circuits. So, a quick check of sunroof corners during each car wash can save significant repair costs and safety hazards. Developing this habit is crucial—don't wait until water drips to panic.

The leakage in the Mingtu sunroof is often caused by damaged or clogged sealing strips. Simply put, the strips can age and harden over time, creating gaps where rainwater seeps in. Additionally, clogged drainage holes are common—if debris accumulates on the roof, water can't drain and may drip onto the seats. The consequences can be serious: soaked carpets lead to odors and even bacterial growth, which is harmful to health. I recommend checking that the sunroof is tightly closed before rain and regularly clearing debris from the corners by hand. Small issues, if ignored, can lead to costly repairs and frustration. In short, paying attention to daily details ensures a comfortable and safe journey.
