How to Deal with the Sunroof Noise in the Envision?
4 Answers
Fully open the sunroof, clean it with a soft cloth, remove debris from the tracks, and apply a non-sticky, non-absorbent lubricant to the sunroof's transmission tracks. Here are specific details about the Envision: 1. The Envision is positioned as a midsize SUV with a relatively large body size and ample interior space. In terms of price, it is positioned around 200,000 RMB. The car's exterior design exudes a sense of power while maintaining a stylish look, making it an ideal choice for young drivers. 2. In terms of design, the 2019 Buick Envision features a newly designed intelligent drag-reducing grille, aluminum roof rails, newly styled chrome dual exhaust pipes, 19-inch multi-spoke aluminum alloy wheels, and multifunctional exterior mirrors. 3. For the interior, the 2019 Buick Envision continues Buick's luxury concept, equipped with front multifunctional seats, adjustable-angle rear sliding seats, a large split central storage box, a heated steering wheel, a two-piece oversized panoramic sunroof, and an 8-inch HD touchscreen.
Last time I drove the Envision on rough roads, the sunroof creaked annoyingly, which turned out to be due to dust buildup in the tracks. The cleaning process is quite simple: first, use a vacuum to remove sand and debris from the track gaps, then wipe the guide rails on both sides with a damp cloth. After air-drying, apply special sunroof lubricant. If the noise persists, it’s likely due to aging seals—replacing the seal strip with a Taobao purchase for around 100 RMB can fix it. Rubber conditioner can also serve as a quick fix; spray it on the seal and let it sit for half an hour to noticeably reduce noise. Those with good DIY skills can adjust the screw tightness themselves, but avoid tampering with the brackets, as improper handling may require replacing the entire assembly. Final reminder: never use WD40 on the tracks! It corrodes rubber. If the noise persists after treatment, head straight to the 4S shop to check for bracket deformation issues.
I know all about sunroof rattles! Especially that squeaky noise on bumpy roads. First, check if the rubber seal is deformed by running your hand along the sunroof edge to see if it's warped. I always keep a can of dashboard wax handy and spray the seals monthly to prevent aging. Another magic trick is fuzzy cloth tape - just three bucks a roll, stick it on the tracks and the noise reduction is amazing. If there's obvious clicking sounds, it's probably loose screws - grab a T20 wrench from your toolbox and tighten the rear screws. Remember not to overtighten to avoid cracking the glass. Try parking in shade when possible, as heat hardens seals faster. Once I stuffed a rubber band into the track and it stayed quiet for six months - pretty down-to-earth solution, right?
Sunroof rattling is mostly caused by three issues: lack of lubrication on the rails, aging sealing strips, or loose bracket screws. Start with the cheapest solution—first spend fifty bucks on a tube of Volkswagen OEM sunroof grease, applying it to the metal tracks can last half a year. For rubber strip maintenance, Vaseline is more cost-effective than rubber protectants, just ten bucks at the pharmacy. If adjusting screws, be sure to use a torque wrench and keep it under 5 N·m. The most troublesome issue is clogged drainage holes causing water accumulation—I've seen cars leak like a waterfall cave. Here's a testing method: after pouring water, check the dripping speed at the C-pillar; if slower than one drop per second, the drainage tube needs clearing. If you're not confident doing it yourself, just head to the repair shop—a thorough cleaning for two hundred bucks is much cheaper than replacing the entire assembly.
