Volkswagen Tiguan Spoiler Water Leak and Camera Sensor Errors

I bought my Volkswagen Tiguan 4 months ago and the vehicle currently has only about 900 km. After the first wash, I noticed that the spoiler was taking in water. I dried it, but water continued to drip for hours. In addition to this, the vehicle started to give errors in the sensor and camera system. Because of these problems I took the car to the Gebze Aykan service three separate times. On one occasion the vehicle stayed in the service for about 20 days, on another visit it stayed for about a week, and on another for approximately three days. In total, the car has spent a significant time in the service in a very short usage period. Despite this, the service could not produce any solution to the spoiler water leak problem. I have lost my confidence in both the brand and the vehicle due to a problem that occurred in such a new car and could not be resolved despite repeated service visits. I request that the spoiler be replaced or that the seals or insulation of the area where the water leaks in be renewed in a way that permanently eliminates the water intake problem, and that the sensor and camera system errors be completely fixed.
