    Noticed wet carpet on passenger side. Second incident. Had downpour of rain yesterday. My car was involved in an accident a few months ago and was hit on the front passenger side. Wonder if this could have caused leak.

    I have water pooling on the drivers side. The floor mats are soaked after each rain. I have pulled apart the floor to find the problem with no real success.

    After the first day of heavy rain on 9/5 I found water pooling on the driver side floor. I checked doors, windows, moon roof etc to see if everything was closed properly. Upon 2 more days of heavy rain, I found pooling in both driver & passenger side front floor & took it to the agent in Rockville MD. They have had the car for 4 days & have pulled out panels, wipers, fareings etc but have not found a cause. Also with the water pooling the engine check light came on & the park break light is also on although the break has not been enguaged. A warning is issued when driving & this goes off when manually doors are locked. Agent has not yet diagnosed this issue as well.

    Same problem. Water on both drivers side and passenger side. So I tore it all apart and this is what I found. When you remove the outer plastic wheel well piece and the mud flaps you see the factory did not seal the seams in the wheel wells where they force the run off water. All of the water is basically channeled down the seam which allows water to flow into a cavity in that corner. When that cavity is full, it flows into the interior and onto the floorboards. I cleaned out the seams as best as possible and sealed them with strip caulk. I then took the Pilot out for a drive in the pacific Nw where it is currently raining. No surprise there. Anyways,if you have questions on how to fix, send me an email..I have pics to show what I did. cooldeez@hotmail.com

    After winter noticed that both driver and passenger side were damp. Finally all dried up, but now instead of general dampness there is a wet spot. about 4" above the hook for car mats. I'm going to try and use information to fix this myself and hope that it's not something else...
