What Causes the Resonance Noise in the Car Roof?

[LaEva]

Here are the specific reasons and solutions for the resonance noise in the car roof: 1. Manufacturer Issues: If the resonance noise occurs in a new car, it is likely due to installation or configuration problems by the manufacturer. In this case, the owner must replace the entire roof lining; otherwise, the noise will persist. 2. Faulty Components: If the issue lies with certain components, they can be replaced after inspection. For example, replace the door hinge if it is causing noise, or the inner lining panel if it is the source. It could also be due to welding points coming loose, causing friction between steel plates. In such cases, the loose welding points need to be re-welded.

I often encounter roof resonance noises while driving, with annoying buzzing sounds on bumpy roads. This is usually caused by aging and loosened roof liner clips or friction from dust accumulation. I've tried gently pressing to locate the source, and sometimes a slight push stops the noise, indicating a temporary fix is possible. However, the root cause might involve frame vibration transmission or improperly installed components, especially around the sunroof where it's more noticeable. Long-term neglect could lead to greater wear, so it's best not to delay. Last time I went to the repair shop, the mechanic simply reinforced it and fixed the issue. In daily driving, avoiding potholes and keeping the interior clean can help reduce occurrences. In short, while the noise might seem minor, it's irritating, and addressing it promptly saves money and effort.
