Volvo XC90 water intrusion into cabin through sunroof and Intellisafe system requiring full sunroof replacement on Volvo XC90

Some Volvo XC90 owners report experiencing water intrusion into the cabin through the sunroof, which can lead to issues with the Intellisafe system and may necessitate a full sunroof replacement. Common signs of sunroof drain blockage include a wet headliner, water dripping from the headliner, damp carpets, and pooling water in the footwells. Owners of older models, such as the 2004 XC90, have successfully resolved leaky sunroof drains by cleaning debris-clogged elbows, which can save on costly dealership repairs. For newer models like the MY16 XC90, Volvo offers a quick fix that involves installing a new sunroof tub seal and using a kit with new seals to improve water drainage. However, water intrusion may also stem from other sources, such as leaks from components located under the dash. Repairing water damage from sunroof leaks can be expensive, with some owners facing charges exceeding $3,000 for labor and additional costs for sunroof seals. Understanding these issues and potential solutions can help XC90 owners address cabin water intrusion effectively.
