What Does a Rattling Sunroof in a New Car Indicate?

[DeBraxton]

Reasons for a rattling sunroof in a new car: 1. Aging sunroof rubber seals or gaskets: Sunroof seals exposed to prolonged rain or sunlight can deteriorate. Rubber conditioner can temporarily restore their performance; 2. Loose sunroof screws: Loose screws may cause rattling in the headliner or sunroof, and even pose a risk of the sunroof detaching; 3. Dust particles in the sunroof tracks. Sunroof maintenance tips: 1. During car washing, avoid directing high-pressure water jets at the seals, as this can deform them and allow water ingress, while also significantly damaging the seals; 2. On extremely bumpy roads, avoid fully opening the sunroof to prevent excessive vibration between the sunroof and tracks, which could lead to component deformation or motor damage; 3. Before the rainy season, clean dust from the tracks and seal gaps, and apply a small amount of plastic protectant or talcum powder to the seals.
