The causes of abnormal noises in car sunroofs are: 1. Aging of glass sealing rubber strips; 2. Debris in the guide rails; 3. Loose internal fastening screws; 4. Insecure fixation; 5. Loose glass buckles. The methods to address sunroof noises include: 1. Wiping the sunroof slide rails with a soft cloth; 2. Applying butter to the tracks; 3. For rubber and plastic components, clean the surface and apply talcum powder for protection; 4. Regularly inspect the sunroof and tighten any loose screws promptly. The functions of a sunroof are: 1. Enhancing the ventilation inside the vehicle; 2. Renewing the air inside the car; 3. Providing an alternative escape route when doors cannot be used in emergencies.
I remember last year when I was driving, the sunroof kept making squeaking noises, which really annoyed me. The main reason was dust and small stones accumulating in the tracks, causing friction and noise over time. Another issue was track deformation, especially noticeable when driving on bumpy roads. The aging and hardening of the sealing strips also caused them not to close tightly, allowing wind to enter and create strange noises. Loose screws were another problem, so it's important to check and tighten them regularly. I tried spraying some lubricant myself, and after that, it became much quieter. I suggest you also try cleaning the tracks or applying specialized oil first. In short, sunroof noises are common but shouldn't be ignored. If they worsen and affect the opening and closing mechanism, it could become dangerous. Regular maintenance can save a lot of hassle.
