How to Solve the Sunroof Noise Issue in a 2017 Mistra?
3 Answers
Here are the solutions to address the sunroof noise in the Mistra: Use cotton cloth or gauze to clean the sliding tracks. After thorough cleaning, apply a small amount of butter or talcum powder to the tracks to eliminate the noise. Here is some relevant information: 1. The sunroof's sliding mechanism is track-based. Typically, after a period of use (3-6 months), dust and sand particles accumulate in the contact surfaces and gaps of the tracks. If not cleaned periodically, noise will occur. 2. The sunroof system also includes many rubber and plastic components. These materials should not come into contact with oils or sticky substances, as they can be corrosive. To clean rubber and plastic parts, simply use a clean cotton cloth. After cleaning, you can apply a small amount of talcum powder for protection. Regular use of the sunroof can help prevent noise issues.
As a former owner of a Mistra, I also encountered the annoying issue of a creaking sunroof last year. My 2017 model's sunroof always made friction noises during operation, mainly due to dust accumulation in the tracks and insufficient lubrication. I handled it myself: first, I carefully cleaned the dust from the tracks using a soft brush, especially removing small particles from the gaps, then wiped off grease with a clean cloth dipped in alcohol. I bought specialized sunroof lubricating silicone spray online and applied it evenly—avoid using regular engine oil as it attracts dust. After application, I opened and closed the sunroof several times to allow the lubricant to penetrate, and the noise basically disappeared. Checking the tightness of the screws is also crucial—use a wrench to gently tighten the bracket screws, but don’t overdo it to avoid damage. If you lack hands-on experience, it’s safer to visit a professional shop; ignoring sunroof noises can lead to jamming or leaks, increasing repair costs, so regular maintenance is recommended to extend its lifespan. The entire DIY process took about half an hour and cost less than 50 yuan.
Sunroof rattling is mostly caused by dirty tracks or lubrication failure. I recommend starting with simple steps: clean the track dust—use a toothbrush or small brush to carefully remove debris, then wipe with alcohol to remove grease stains before spraying specialized lubricant. Quarterly maintenance can prevent major issues. Next, check if screws are loose and tighten them with a wrench, but avoid excessive force to prevent cracking. If the noise persists, it may indicate aging motors or internal components, requiring professional diagnostic tools. Park away from trees to reduce debris accumulation. Neglecting repairs can lead to minor annoyances like noise or major issues like impaired opening/closing functions and even water leakage during rain. My car repair experience taught me that prevention is better than cure—regular track cleaning saves hassle and money. Similar discussions often arise in the Mistra owner groups, with most feedback suggesting DIY lubrication fixes the issue.
