The reasons for water leakage in the A-pillar of the X-Trail: 1. Clogged sunroof drainage holes: If the sunroof drainage holes are blocked, rainwater that falls on the car cannot be drained in time, and the water will flow along the interface of the conduit into the interior of the A-pillar. 2. Poor windshield sealing: After replacing the windshield, if the adhesive is not applied evenly, the car's sealing will be reduced, and rainwater will flow into the car through the gaps. If the windshield has not been replaced, it is likely that the aging sealing strip is causing the leakage. 3. Aging window seals: The sealing strips of the windows will harden and age over time, reducing the window's sealing. Additionally, if the fixing holes are not properly handled when installing a roof rack, it can also cause water leakage.
My X-Trail previously experienced water leakage in the A-pillar, mainly because the sunroof drain pipe was clogged. Leaves and debris accumulated in the pipe, causing water to backflow into the A-pillar. Another possible reason could be aging door sealant or fine cracks at the A-pillar welding points, allowing rainwater to seep through the gaps. Water leakage not only soaks the carpets and makes the interior floor wet but also easily leads to mold and rust on internal components. To fix it, first, clean the sunroof drain holes to ensure smooth water drainage. If the leakage is severe, use specialized sealant to close the gaps. I make it a habit to inspect the sunroof quarterly as a preventive measure.
