Volvo XC90 passenger side floor carpeting soaked with water sloshing sound, suspected leak from insulation trim on Volvo XC90

Some Volvo XC90 owners report experiencing issues with water accumulation on the passenger side floor, often accompanied by a sloshing sound. This can be caused by a leaking windshield seal, which allows water to enter the vehicle and pool on the carpet. Additionally, clogged sunroof drains can prevent proper drainage, leading to water intrusion inside the vehicle. Some owners also find that a clogged AC evaporator condensation drain results in water buildup on the passenger side floor. Furthermore, an overflowing evaporator core box, particularly after using the air conditioning, can contribute to this problem. It is essential for owners to inspect these potential sources of leaks and blockages to prevent further damage to the vehicle's interior and ensure a comfortable driving experience.
