What Causes Water Accumulation Under the Front Passenger Footwell in a Sedan?

[DelEzra]

If there is water under the car's floor mats, on the driver's side, front passenger side, or beneath the rear seats, it may be due to issues with the sunroof, poor body sealing, or the vehicle driving through deep water. It is crucial to promptly address water that has seeped under the floor mats or carpet. Failure to do so can lead to mold growth inside the car and damage to wiring harnesses or control units. Common causes of water leakage include: 1. Sunroof leaks: Poor sealing. 2. Clogged or detached sunroof drainage holes: Preventing water from draining out of the vehicle. 3. Poor body sealing: Leakage during rain. Check the door drainage channels. 4. Vehicle water immersion: Driving through deep water, allowing water to enter the cabin.
