Why does the Tiguan sunroof fail to close when tilted upwards?

Tiguan sunroof failing to close when tilted upwards is usually caused by foreign objects in the sunroof guide rails or a malfunction of the sunroof motor. If there are obstructions in the sliding rails or insufficient lubrication, excessive resistance may prevent proper closure. First, check the sliding rails: When lubrication is insufficient and resistance is too high, the sunroof's automatic anti-pinch feature will activate, manifesting as failure to close. The main maintenance for sunroofs involves lubricating the sliding rails. Lack of lubrication over time can lead to abnormal noises, poor movement, incomplete sealing, or even jamming and displacement, potentially burning out the motor. Check the electrical system: Inspect whether the electric sunroof's fuse has blown. If the fuse is intact, examine whether the sunroof switch is damaged. Press the switch to check if power is being supplied. If power is present, then verify whether the sunroof's drive motor is functioning by listening for any operational sounds. Additionally, failure to close tightly may be due to obstructions, deformations, rust, or poor lubrication in the sunroof's sliding channels.
As a Tiguan owner, I've also encountered the issue of the sunroof getting stuck in the tilted position and failing to close, mainly due to some common causes. Dust or small stones accumulated in the tracks can jam the sliding channels, especially when driving in rainy or dusty areas. Insufficient lubrication of the rails or aging components can also cause the sunroof to get stuck in the tilted position. Another possible issue could be a faulty control switch or motor, such as a short circuit causing system failure. On my car, frozen seals due to rainwater in the rainy season can also cause this. When addressing the issue, avoid forcing the sunroof closed as it can damage components. It's recommended to manually clean the tracks or have them inspected by a professional. Regularly cleaning the sliding channels every quarter can prevent most of these problems.
My car keeps having this issue where the sunroof tilts up but won't close. I've learned to handle it myself: open the cover to check the tracks, usually clogged with debris like leaves or dust stuck on the sliding rails, just clean them thoroughly. Lubrication is also important, buy some specialized oil and spray it on the guide rails to prevent sticking. Electrical problems occasionally occur, with the switch button responding sluggishly, requiring a trip to the shop for part replacement. A friend's car had a similar situation, mostly track-related issues, simple DIY can fix it at low cost, but it's better to address it early to avoid water leakage damaging the interior.
