Will a car with a sunroof leak when it rains?

[ValerieLynn]

"A vehicle with a sunroof will not leak during rainy days as long as regular maintenance is performed on the sunroof. Below are the relevant details: Sunroof maintenance: Clean the drainage pipes every two years and apply appropriate lubrication to the sunroof rails. Regularly clean the surrounding areas of the sliding rails—generally, use a damp cloth to clean the rails every two months on average, followed by applying a small amount of engine oil for lubrication. Function of a sunroof: Installed on the roof of a car, a sunroof effectively promotes air circulation inside the vehicle, increasing the intake of fresh air, providing drivers with a healthy and comfortable experience. Additionally, a car sunroof can broaden the field of vision and is often used for mobile photography and videography needs. Sunroofs can be broadly categorized into: sliding-out, built-in, built-in flip-up, panoramic, and curtain-style types. They are primarily installed on commercial SUVs, sedans, and other vehicle models."
