How to Solve the Creaking Noise of Haval H6's Panoramic Sunroof?
2 Answers
Solutions for the creaking noise of Haval H6's panoramic sunroof: (1) Adjust the sunroof's flatness and gap within the tolerance requirements, clean the contact surface between the body seal strip and the front glass, and then apply lubricant. (2) Loosen the bolts of the sunroof glass, insert a feeler gauge (2mm, or use a work ID card or bank card as a substitute) between the front end of the glass and the roof seal strip to ensure sufficient gap between the glass and the seal strip, then adjust the glass to be flat and tighten the bolts. (3) Check if there is lubricant in the mechanical group track; if not, add lubricant. If signs of interference wear are found, slightly grind the bottom, then reinstall the sunroof glass and adjust its height as required. More details are as follows: 1. If there is a friction sound when the sunroof glass is tilted and closed, the cause may be: lack of grease in the plastic guide rail slot, leading to dry friction between the guide rail and the plastic slot. Solution: Remove the front sunroof glass and apply grease in the plastic slot. Additionally, if there is a friction sound when opening the sunroof glass or driving on uneven roads, and pressing upward on the sunroof glass also produces a friction sound, then apply grease in the limit groove. 2. If there is abnormal noise when driving on uneven roads, the cause may be: friction between the sunroof glass and the soundproof seal strip or roof seal strip. Solution: Adjust the gap and flatness of the sunroof glass; remove the soundproof seal strip and apply lubricant on the drainage channel frame; clean the body seal strip and the sunroof glass seal strip, and apply lubricant on the seal strips.
My Haval H6's panoramic sunroof squeaks every time I open or close it, which is quite annoying. I've encountered this issue several times. Start with the simplest solution: cleaning the sunroof tracks is the most common fix, as dust or small stones stuck there can cause scraping noises. Try wiping the tracks clean with a soft cloth or small brush. If the noise persists, it might be a lubrication issue—the tracks could be aging and becoming stiff. Buy some sunroof-specific lubricant from an auto parts store and apply a thin layer. Remember not to use engine oil or grease, as those attract more dust and make things worse. If the sound comes from the sealing strip, check if it's cracked or loose; aging strips can rub and squeak over bumps. Small cracks can be temporarily sealed with adhesive, but severe damage requires a replacement. I've also tried tightening screws—loose support structures can cause resonance noises, so use a wrench to tighten all visible bolts. Finally, if the noise is especially loud when opening or closing on bumpy roads, the frame might be deformed, requiring adjustment at a 4S shop. In short, many issues can be solved DIY, and regular cleaning and lubrication can prevent squeaks.
