What Causes the Abnormal Noise in a Car Sunroof?
2 Answers
Car sunroof abnormal noise is caused by: 1. Aging of the sunroof rubber seal or sealing ring; 2. Loose sunroof screws; 3. Dust particles in the sunroof sliding track. Solutions for car sunroof abnormal noise: 1. Open the sunroof fully and spray maintenance agent on the rubber seal; 2. Locate the sunroof screws and tighten them; 3. Remove dust with a towel and perform regular maintenance. Car sunroof maintenance recommendations: 1. During car washing, avoid directing high-pressure water jets straight at the sealing ring; 2. On extremely bumpy roads, it is best not to open the sunroof completely to prevent deformation of related components or damage to the motor due to excessive vibration between the sunroof and the sliding track; 3. The biggest concern when using a sunroof is rain or water leakage, which can be effectively avoided with proper use and maintenance of the sunroof.
I've been driving for over a decade, and sunroof rattles are way too common. The most frequent cause is small pebbles stuck in the sliding tracks or thick dust buildup—you'll hear creaking noises when operating the sunroof. Last time I cleaned the tracks, I even found the lubricant had dried into clumps, causing direct metal friction and screeching sounds. If your car is often parked under trees, leaves or dirt embedded in the sealing strips can also create rattles. If the noise is especially noticeable on bumpy roads, check if the roof's mounting screws are loose—I once had loose screws that made the entire frame shake. My advice: use a soft brush to clean track gaps during every car wash and apply dedicated track lubricant every six months—this usually solves most rattling issues.
