Solutions for the rattling noise in the Emgrand sunroof: 1. Check the sunroof sliding rails and apply some lubricating oil if necessary; 2. Inspect the sunroof's fixation, as looseness may also cause the noise; 3. The sunroof sealing strip, when exposed to prolonged rain or sunlight, is prone to aging. Open the sunroof fully and spray rubber conditioner on the sealing strip; 4. Adjust the sunroof screws. The Emgrand's body dimensions are 4632mm in length, 1789mm in width, and 1470mm in height, with a wheelbase of 2650mm. The Emgrand comes in two models with different engine displacements, equipped with a 1.5L naturally aspirated engine and a 1.3T turbocharged engine respectively.
If the sunroof of my Emgrand squeaks, I first check if there's dust on the sliding rails. Last time my car had this issue, it was due to leaf debris clogging the tracks, causing the glass to open and close unevenly. Cleaning it with a brush solved the problem. If cleaning doesn’t help, apply some special rail lubricant—the white paste kind—avoid using grease as it attracts dust. If the noise persists, inspect the sunroof seal; if it’s aged or deformed, it may rub against the glass. Replacing the seal costs just around a hundred yuan. As a last resort, check the screws—over time, the body frame may loosen, and tightening a few screws can eliminate the noise. Remember to rinse the rail gaps during car washes and operate the sunroof twice a month to maintain flexibility.
I follow a three-step approach to address sunroof rattling: First, identify the source of the noise by tilting the sunroof open to check if the clicking sound comes from the sliding rails. Then, open the sunshade and use a flashlight to inspect the tracks. Clean out any debris or dirt with cotton swabs, and wipe the metal tracks with a WD40-sprayed cloth. If the rubber seals feel stiff, apply rubber protectant—never use cheap engine oil as it can corrode the rubber. Finally, test the sunroof by sliding it open and closed. If the noise persists, consider visiting a shop to adjust the bracket position. Remember, temperature fluctuations between winter and summer can cause rubber seals to crack, so slightly open the sunroof first to equalize air pressure.
Cleaning the tracks is crucial. I used a discarded toothbrush and vacuum cleaner to address the abnormal noise three times. First, brush out the sand particles in the track grooves with the toothbrush, then use the vacuum to remove the dust, and finally apply silicone-based grease. Also, check if the screws are loose; the cross-head screwdriver in the trunk toolkit can tighten the screws around the sunroof frame. If the rubber seal is aging, buying the same model on Taobao and replacing it yourself isn't difficult, but pay attention to aligning the slot positions. Try to avoid opening the sunroof on bumpy roads.
