Why does the Xuan Yi sunroof bounce back when closing?
2 Answers
Xuan Yi sunroof bounces back when closing because there are foreign objects in the sunroof slide rail, or the slide rail lacks lubrication, causing excessive resistance, which leads to the sunroof bouncing back when closing. Here are some maintenance tips for the sunroof: 1. Protection of the sealing ring: When washing the car, pay attention to the protection of the sealing ring. Do not use a high-pressure water gun directly on the sealing ring to avoid deformation, which may cause water leakage. 2. Regularly wipe the sealing ring: Regularly wiping the sealing ring can prevent premature aging of the sealing ring. Do not use cleaning agents with high acidity or alkalinity to avoid corrosion of the sealing ring. 3. Drainage channels: Regularly clean the drainage channels in the four corners of the sunroof to prevent clogging of the drainage holes, which may cause water seepage on the roof and affect the use of the sunroof components. 4. Poor road conditions: If the car is driven on poor road conditions, try not to open the sunroof when the car is bumpy to avoid damage to the sunroof slide rail.
My Sylphy's sunroof had the same issue, and I was quite anxious because it kept bouncing back halfway when closing. Later, I discovered several common causes: dust accumulation or small leaves stuck in the tracks can trigger the sunroof's anti-pinch function to prevent hand injuries; insufficient lubrication in the sliding rails increases resistance, making the system think there's an obstacle; sometimes, it's a false sensor alarm or a fault in the motor wiring. I checked the tracks, cleaned out the debris, added a bit of lubricant, and tried again—problem solved. It's not a major issue, but timely action is crucial; otherwise, rainwater leaking into the car could damage electronic components, leading to bigger troubles. Developing a habit of wiping the tracks with a soft cloth every month can save a lot of hassle.
