Does long-term non-use of the sunroof have any impact?

If the sunroof is not used for a long time, proper maintenance should be performed to prevent the rubber seal from aging and causing water leakage. It is advisable to frequently use the sunroof's sliding mechanism to maintain its lubrication and flexibility. Hazards of clogged sunroof drainage outlets: If the drainage holes in the four corners are blocked, accumulated water cannot drain properly and may seep into the interior. In severe cases, water may flow along the roof to the sunroof motor inside the vehicle. Once powered on, the sunroof motor is prone to short-circuiting and burning out. Methods for cleaning clogged sunroof drainage outlets: Initial blockages usually occur at the entrance of the drainage holes, which can be easily seen and cleaned by opening the sunroof. Over time, debris may enter the drainage hose and move further inside, making it more difficult to clear. In such cases, it is best to visit a 4S shop for professional cleaning by a technician.
Not opening the sunroof for a long time can really cause problems. The sealing strips age faster, and the rubber can harden and crack. On rainy or windy days, water can seep into the car through the gaps, wetting the carpets and seats. The tracks may rust or get stuck, and dust and dirt can accumulate, causing the sunroof to squeak when opened, or even get jammed—either not opening or not closing tightly, making operation less smooth. A clogged drainage channel is even worse; leaves and debris can pile up, obstructing water flow. Accumulated water can corrode the metal structure of the roof, leading to rust or unpleasant odors over time. I once spent several hundred dollars fixing this issue. Additionally, poor air circulation inside the car can lead to high humidity, which fosters bacterial growth. I recommend opening the sunroof at least once a month to ventilate and check its condition, while also cleaning the tracks and applying some lubricant. Small habits like these can extend its lifespan.
