Why doesn't the sunroof close smoothly?

Because there is dust on the sunroof track that hasn't been cleaned, this dust can prevent the sunroof from closing tightly. Lift the rear of the sunroof and hold the switch for one minute, after which the sunroof will close completely. Below are some related tips for using the sunroof: 1. When driving on bumpy roads, it's best not to slide the sunroof fully open; slightly closing it can extend its lifespan by several years. Fully opening the sunroof on rough roads can damage the motor. 2. Open the sunshade before opening the sunroof. Failing to do so may not cause immediate issues, but over time, it can lead to malfunctions. Additionally, extra caution is needed when using the sunroof in winter. After snowy or rainy weather, the sunroof can easily freeze, causing the sealing strip to harden. Forcing the sunroof open in this state can break the sealing strip. The solution is to turn on the car's heater to melt the ice on the sunroof before opening it. 3. Be especially careful when washing the car. Avoid directing high-pressure water jets at the sealing strip. It's important to know that the sunroof has four drainage channels at each corner to drain water. However, if these channels are blocked by leaves or dust, water can overflow, leading to common roof leakage or even severe water ingress. Regularly clean the sunroof's drainage outlets to prevent such issues.
Oh, I also encountered the issue of the sunroof not closing properly in my car last year. It was mainly because there was too much debris stuck in the tracks, like leaves and dust, which built up over time and made the sunroof slide less smoothly. It could also be due to a motor malfunction, where the motor doesn't have enough power, or insufficient lubrication, causing excessive friction in the sliding parts and preventing a tight seal. I recommend regularly cleaning the tracks with a soft cloth and adding some lubricant to reduce such problems. If you can't fix it yourself, it's best to consult a professional, otherwise water leakage into the car can cause trouble, affecting the interior environment and wasting electricity. Also, try to avoid parking under trees to minimize debris accumulation—safety first when driving, right?
