What to Do About the Sunroof Rattling in Fista?

The causes of sunroof rattling are as follows: 1. Sunroof rubber seal or gasket: Aging of the sunroof rubber seal or gasket. Prolonged exposure to rain or sunlight can cause the sunroof seal to age. Rubber conditioner can temporarily restore the seal's performance. Open the sunroof fully and spray the conditioner on the seal. Of course, the direct method is to replace the sunroof rubber seal. 2. Sunroof screws: Loose sunroof screws. Loose screws can cause rattling in the headliner or sunroof, and even pose a risk of the sunroof falling off. The solution is simple: locate the sunroof screws and tighten them. 3. Sunroof sliding track: Dust particles in the sunroof sliding track. Frequent opening and closing of the sunroof inevitably leads to dust accumulation in the track gaps. When enough dust accumulates, friction occurs during sunroof operation, causing rattling. Use a towel to remove the dust, and regular maintenance is important.

Last time my sunroof made strange noises, I carefully cleaned the grit and tree sap from the rubber seal gaps with a damp cloth. After drying it, I applied a layer of rubber protectant. Surprisingly, the noise disappeared the next day when I drove. By the way, aged and wrinkled sunroof seals can also produce creaking sounds, just like the friction noise from leather jackets in winter. If the rubber hardens and cracks, you'll need to replace the seal. You can buy a new one online for around a hundred yuan, and using a hairdryer to soften it during installation makes fitting easier. Try not to park under trees with falling leaves, as tree sap corrodes rubber very quickly. Of course, if the noise only happens on bumpy roads but not when stationary, you should check the sunroof brackets.

I know all about sliding rail noises! I was tormented by that rustling sound for two months before mentioning it during a routine service at the dealership. The technician blew out three small pebbles with an air gun and applied special white lubricating grease. Turns out, clogged sunroof drainage holes causing water leakage can also corrode the rails, leading to metal-on-metal scraping sounds. It's recommended to clean the guide rail channels quarterly – avoid using WD-40 as it attracts more dust. If you experience jerky movement accompanied by clicking noises, it might indicate deformed tracks or damaged motor gears, which would require headliner removal for repair.

I've encountered many cases of sunroof rattling during car repairs. The most hidden one is loose screws: just tighten the fixing screws at the four corners of the sunroof base with a hex key, being careful not to use too much force to prevent stripping. Another owner had a panoramic sunroof that creaked at the rear half—turned out to be broken clips on the roof liner. Here's a little-known fact: when ground temperatures exceed 60°C in summer, the metal parts of the sunroof can expand and deform. If it rattles in high temperatures but not in low temperatures, this is likely the issue.
