Is It Normal for a Sunroof to Leak?
2 Answers
Generally speaking, a sunroof should not leak. Here is some relevant information about sunroofs: Functions of a sunroof: It can quickly lower the temperature, eliminate fog, and allow for rapid air exchange. Opening the sunroof while driving can quickly increase the speed of air circulation inside the car, thereby improving ventilation in the cabin. Precautions for using a sunroof: Open the sunroof in traffic jams to prevent exhaust fumes from entering the car. During traffic jams, when all vehicles are stationary, car exhaust will inevitably disperse in the air. Open the sunroof after exposure to the sun to balance the interior temperature. In hot summers, after the car has been exposed to the sun, the interior temperature becomes very high. At this time, the owner should promptly open the sunroof.
I've been driving for many years and have encountered sunroof leaks a few times, but it's definitely not normal. It's designed to be tightly sealed, but if the drainage holes get clogged—like from dust or leaves when parked under trees—water has nowhere to go and seeps in. Once, my headliner got soaked, the seats grew mold, and I had to spend a fortune on major repairs. Make sure to clean those holes regularly and check before rainy days—don’t be lazy. Long-term neglect can lead to short circuits in the electrical system, and the repair costs can be shockingly high. As someone with experience, I flush the drains with a soft hose every three months—it’s quick and hassle-free. Also, don’t overlook aging seal strips, especially in older cars—replace them in time, or leaks will happen sooner or later. Fellow drivers, regular maintenance saves headaches—safety first.
