Why does the Sportage sunroof automatically bounce back when closing?

This may be caused by the anti-pinch function being triggered. The anti-pinch function may activate when the sunroof encounters excessive resistance during closing, which is often due to insufficient lubrication in the sunroof tracks. Car owners can apply some grease to the sunroof guide rails. Types of car sunroofs: Automotive sunroofs can be broadly categorized into: sliding-out type, built-in type, built-in flip-up type, panoramic type, and curtain type. They are mainly installed on commercial SUVs, sedans, and other vehicle models. Functions of car sunroofs: Experts explain that air pollution inside vehicles severely affects the health of drivers and passengers, especially after the car has been closed for a period, when the cabin is filled with harmful gases such as benzene and formaldehyde from interior decorations. Therefore, the first thing to do after overnight parking is to open the sunroof, utilizing its superior negative-pressure ventilation principle to filter the cabin air and protect the health of occupants. Sunroofs revolutionize traditional ventilation methods: Car sunroofs change the traditional ventilation pattern by allowing wind to create airflow that draws out stale air from the cabin. When driving at high speeds, air flows rapidly around the vehicle. Opening the sunroof creates a negative pressure zone outside the car, which, due to the pressure difference between inside and outside, extracts polluted air from the cabin, achieving ventilation and maintaining fresh air inside the vehicle.
Hey, speaking of this issue, I think it might be something stuck in the sunroof tracks or accumulated dust. The anti-pinch function sensed resistance and automatically retracted to prevent pinching. I’ve experienced this with my own car before—suddenly it started raining while driving, and the sunroof wouldn’t close and kept bouncing back. It was so frustrating! After checking, I found leaves and small twigs clogged in the sunroof gap. Once cleaned, it worked fine again. You can try fixing it yourself: first, use a soft cloth to wipe away dirt from the tracks, then apply some sunroof-specific lubricant, avoiding excessive force. If that doesn’t work, you’ll need to visit a repair shop to check if it’s a motor or sensor issue—safety first, don’t delay driving. Regular maintenance, like cleaning the sunroof periodically, can help avoid such hassles. Also, an improperly sealed sunroof might lead to water leakage into the cabin, damaging the interior, so don’t underestimate this problem.
