Having a sunroof in your car can indeed be a delightful feature. A glass sunroof allows more light into the cabin, provide additional ventilation and comfort for the occupants. On a nice day, it’s fun to slide the roof back and enjoy the open sky. However, sunroofs can also cause major repair issues.
Mechanical Failures
Mechanical failure of sunroof components can render it inoperable, which is particularly problematic if it gets stuck open. This could expose the interior to the elements, leading to potential damage.
Glass Cracks
Glass sunroofs can crack due to mechanical problems or road debris. Replacing a cracked sunroof panel can exceed $1,000, depending on the vehicle and the cause of the issue.
Water Leaks
One of the most costly issues is when the sunroof leaks, allowing water to enter the vehicle. Water can damage wiring and electrical control modules located below the seats and carpeting, causing short circuits and a myriad of issues, often leading to a large repair bill. Additionally, water can cause mold to grow, leading to potential health issues if not addressed quickly.
The most common cause of water entering the vehicle from the sunroof is plugged sunroof drains. Sunroofs are not water-tight even when closed; these drains are designed to move water that gets past the sunroof seal into the sunroof channel. When sunroof drain tubes get clogged with leaves, dirt and debris, water can back up and allow water to flow into the cabin. Signs of this issue include water stains on the headliner, water dripping from the ceiling, a musty smell inside the vehicle, or a sloshing sound when driving.
Prevention and Maintenance
To avoid debris plugging the sunroof drains, it’s important to have the drains cleared regularly. While most manufacturers have no recommended servicing intervals for the sunroof, it is wise to have the drains cleaned every two years, especially if the car sits outside and is subject to leaves and dirt. Generally, a shop can clean the drains for under a couple hundred dollars, which can save you thousands of dollars in the event of water damage.
While your insurance company may cover the cost of repair, you would be responsible for the deductible, and making an insurance claim could increase your rates. Regular maintenance of the sunroof drains is a cost-effective way to prevent major issues and ensure your sunroof remains a pleasant feature of your vehicle.
