Introduction to the causes of abnormal noise in the Boyue sunroof: 1. Aging of the sunroof rubber seal or sealing ring. The sunroof seal is often exposed to rain or sunlight, making it prone to aging. Rubber conditioner can temporarily restore the seal's performance. Open the sunroof fully and spray the conditioner onto the seal. Of course, a more direct solution is to replace the sunroof seal. 2. Loose sunroof screws. Loose screws can cause noise in the roof lining and the sunroof, and may even pose a risk of the sunroof detaching. The solution is simple: locate the sunroof screws and tighten them. 3. Dust particles in the sunroof sliding track. Frequent opening and closing of the sunroof can lead to dust accumulation in the track gaps. When enough dust accumulates, friction occurs during operation, causing noise. Use a cloth to remove the dust, and regular maintenance is essential.

I previously dealt with the issue of a squeaky sunroof on the Boyue. It's usually caused by excessive dust accumulation in the tracks. First, use a small brush along with a vacuum cleaner to remove sand and leaves from the track gaps. Then, purchase sunroof-specific lubricant from a hardware store and apply a thin layer on the metal strips on both sides of the tracks, being careful not to get any on the rubber seals. If the noise persists, check the sunroof bracket screws and tighten any loose ones with a Phillips screwdriver. After regular use, make sure no leaves remain in the sunroof groove. Performing a simple cleaning once a month can effectively prevent the squeaking from recurring.

I make it a habit to check the sunroof before driving. If there's any unusual noise, I immediately clean the tracks, paying special attention to removing gravel from the corners of the guide rails. Then, I spray WD-40 lubricant on the metal sliders. After spraying, I don't rush to close the sunroof; instead, I let it ventilate for half an hour. If the noise worsens on bumpy roads, it might be due to aged or deformed rubber seals, in which case new sealing strips need to be replaced. I recommend using cotton swabs to clean the grooves of the seals during car washes to maintain their elasticity and reduce friction noise. It's especially important to clean after opening or closing the sunroof on rainy days, as accumulated water mixed with dust can cause more friction and noise.

To fix sunroof rattling, target the root cause. Debris in tracks is the main culprit – use compressed air to blow out gaps. Hardened seals require replacement; OEM weatherstrips cost around a hundred yuan. For bent brackets, adjust mounting screw positions – minor tweaks of a few millimeters with a hex key work wonders. Keep rubber conditioner handy for regular anti-aging treatments on seals. For stubborn cases, visit a repair shop where have specialized track alignment tools. Never ignore minor rattles – prolonged vibration may cause permanent bracket deformation.

Last week, I just dealt with the rattling issue of my Boyue sunroof. First, I used an old toothbrush dipped in water to clean the sludge from the guide rails, then dried it with a hair dryer. Next, I applied bicycle chain wax as a lubricant—cheap and practical. During the opening and closing test, I noticed the right-side bracket spring was loose, so I reset it with pliers, which solved the problem. Before starting, I recommend keeping the manual in the car to refer to the structural diagram. Normally, try to avoid parking under large trees to reduce the chance of leaves falling into the sunroof gaps, which can save a lot of cleaning hassle.

For the abnormal noise issue with the Boyue sunroof, I recommend a three-step solution. First, clean dust and debris from the tracks—using alcohol-soaked cotton pads works best. Then, lubricate the metal sliding rails with lithium-based grease, which lasts longer than regular engine oil. Finally, check the tightness of all screws, ensuring the four corner fastening screws are fully tightened. After completing these steps, test by opening and closing the sunroof five times consecutively. A reminder to new car owners: wash your car frequently, especially after rainy seasons, and clean the sunroof drainage outlets. Blockages in the drainage channels can also cause abnormal vibration noises.
