What is the reason for the abnormal noise in the Ruicheng CC sunroof?
3 Answers
The reason for the abnormal noise in the Ruicheng CC sunroof is severe lack of lubrication in the slide rails. The slide rails should be checked for deformation and lubricated in a timely manner. The main maintenance for the sunroof is the lubrication of the slide rails. If lubrication is insufficient, over time there will be abnormal noise, poor movement, incomplete closure, or even jamming and displacement, which can burn out the motor. The Ruicheng CC is the first model under Changan's new design language, positioned as a sports mid-size sedan, built on Changan's new P3 platform. In terms of body dimensions, the Ruicheng CC measures 4780mm in length, 1825mm in width, 1465mm in height, with a wheelbase of 2770mm.
I've repaired many cars with sunroof rattles, and there are several common causes. The most frequent issue is loose track screws causing a rattling noise on bumpy roads. Aging seals with hardened rubber often produce squeaking sounds from friction. Debris or dirt accumulation in the tracks can create rolling noises, while insufficient lubrication increases friction sounds. More serious hidden dangers may come from deformed or loose internal brackets.
Simple DIY solutions:
1. Clean the tracks thoroughly with a damp cloth
2. Apply silicone-based lubricant specifically for sunroofs (avoid regular engine oil as it attracts dirt)
If the noise persists:
- Check screw tightness
- Visit a professional repair shop if necessary
Preventive maintenance:
- Lubricate quarterly to prevent minor issues from escalating
Safety reminder:
Unaddressed rattles may lead to sunroof jamming or water leakage, increasing risks. Always prioritize safety.
My Ruicheng CC's sunroof started squeaking annoyingly last year. At first, I thought it was normal for a new car, but the noise kept getting worse. After searching online, I learned the tracks might be dirty. I cleaned them myself using a vacuum to remove leaves and dust, then applied lubricant spray, which reduced the noise by half but didn't eliminate it completely. A friend suggested checking the screws, and I found the front track was loose. Tightening it fixed the issue entirely. The whole process saved money and hassle. The lesson: don't ignore strange noises—simple maintenance can often solve the problem. Now, I check and clean the tracks monthly to prevent dust buildup and extend the parts' lifespan. If DIY doesn't work, it's best to visit a 4S shop for professional help rather than experimenting blindly.
