Problem Description and Possible Solution
On certain models a leaking side marker light wire harness can cause a water leak inside the vehicle. Resealing the wire harness where it goes through the body into the cabin area should stop the leak.

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. firstname.lastname@example.org
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.
I have water pooling on passenger side floor. Have checked under mat, wheel well drain, no sunroof. I believe its the I beam seal or wire harness holes behind front quarter panel. Wondering why no recall from honda with so many people with same problem?
Just bought a certified pre-owned pilot two weeks ago and when I vacuumed it out yesterday I noticed that both the front drivers side and passengers side floors were wet (passengers side was soaked)I cleaned and dried both sides and this morning we had another rain storm so I went out to check the floor and there is another puddle on the passengers side, my car has not moved so I know it wasn't from driving through a puddle or anything else the dealer was trying to blame on me. Now I will begin to fight with the dealer until they fix this problem.
water leak started on pas. side..now driver's side too.
Just noticed the last few days water has been collecting on both driver and passenger sides under mats. Have tried to dry it out completely with no luck (cold and snowy/rainy here). Taking it to Honda tomorrow, was just trying to see if anyone had the same problem so I know what to expect.
Water on passenger side floorboard, then drivers side as well. Going to try to seal those seams under the wheel well.
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.
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.
My passenger front side started getting leak from the bottom of the carpet, I really can't figure out where the water is coming from, I remove the carpets, cables. left panel, windshields, inside the tire also. I placed my hand underneath of the glove box and the water comes from the car metal near the box cable. I took my car to this Honda dealer we have in Colorado Springs and the Manager said that they have never heard that any Honda Pilot has this problem. I told him to Google it and that I am not B...ing and he said that my car is old and things just wear out when is old. WTF? He said bring the car but it will cost you. I am so disappointed with Honda, they know this problem is happening and they don't do anything for their customers.

Water is coming in on the driver's side under the electrical panel
I have same problem water leaks
I have the same wet floorboards on my 2004 Pilot. The passenger side is wetter than the driver's side. I believe I have discovered where the water is coming from. I removed the nut holding the passenger side fusebox so I could pull it back. There is a hole in the metal (vertical surface) that is approximately 3/4". It looks innocent enough. When I pushed a rolled up paper towel into it a large volume of water immediately absorbed into the paper towel. I then put a popsicle stick partly in, and water rolled out down the stick. There is some type of cavity behind that hole that is filled with water. I don't know if there is supposed to be a rubber plug in this hole but there is nothing now. I also wonder if there is supposed to be a drain for water that accumulates there. I need to figure out why water is accumulating and sitting there. If I simply plug up the hole there will still always be water in there. Please comment if you have found the same issue. Thank you.
Leak on passages side floor.
We have just had some very heavy rain during the last few weeks and have now noticed the front passenger side carpet is very wet and the driver side getting wetter.
I called 2 Honda service centers and both don't know of a problem but it seems lots of Honda Pilots have this issue....so annoying as this has been a great car!
Bought pre-owned at dealership 1 year ago...discovered both driver's side and passenger side floorboards are soaking wet :-(
I have a leak on the drivers side that is causing the footwell to collect water when it rains. Does anyone know if there is Service Bulletin that shows how to repair this? I asked my Dealer about this when I brought my car in for other recall repairs. They looked at me as though they've never heard of this issue.
My car has had this issue for about 2 years.
I have been reading the blogs about the issue with the side marker light harness going through the body into the interior. I will give it a try. This has been driving me nuts.
still leaking. I am looking for a solution on-line now.
