Why does the Volkswagen Tiguan sunroof pop up and fail to close?
2 Answers
The reasons why the Volkswagen Tiguan sunroof pops up and fails to close are as follows: 1. There are foreign objects in the sunroof's sliding track; 2. The sunroof motor's return function has malfunctioned; 3. Insufficient lubrication in the sliding track, causing excessive resistance when closing the sunroof. Note: Do not force the sunroof to close when this issue occurs, as it may lead to damage to the sunroof glass. Vehicle sunroof maintenance methods are as follows: 1. Regularly clean the sunroof's sliding track: This ensures smoother opening and closing of the sunroof; 2. Regularly inspect the vehicle's sunroof: During vehicle use, periodically check the sealing of the sunroof's rubber seal. Poor sealing can result in water leakage. When driving on bumpy roads, ensure the vehicle's sunroof is closed.
I also encountered the issue of the sunroof tilting up and not closing properly when I drove a Volkswagen Tiguan before. It was really annoying. Usually, it's because the sunroof track is stuck, possibly due to dust or leaves blocking the sliding channel, causing the slider to move poorly. Or, the track might lack lubricant, becoming dry and stiff over time. I suggest you try gently pushing the front edge of the sunroof to help it reset slowly, but don't use too much force to avoid damaging the parts. If that doesn't work, quickly clean the track with a vacuum or spray some track lubricant. This issue is quite critical—if the sunroof is open and can't be closed, water might get in during rain, ruining the interior and creating excessive noise at high speeds, which affects safety. So don't delay; it's best to have a professional repair shop thoroughly inspect it, as it could be a motor or sensor issue. For prevention, I clean the sunroof track every three months, and now I rarely have problems.
