Questions about apparent interior water leak - 2014 CRV

Hello! My 2014 CRV EX-L w/ sunroof appears to have developed a water leak. It became apparent after a heavy rain earlier this week. However, the dealer I took it to (have never been there before) is having trouble confirming that the water inside is from a leak and not from either the car having been flooded (nope) or me having left the windows/sunroof open (double nope).
Here is the timeline and description. Any insight is appreciated!

1. Heavy overnight rainstorm. When I got into my car the next morning (it is parked outside), I noticed that the headliner on the driver side was soaking wet near the front between the window and visor. When I began driving, I could *hear* water sloshing in the roof on the driver side. It was most apparent when I sped up to 20+ and then braked to a stop. I didn't check the floor for water and didn't notice any, possibly because I have all-weather mats.

2. Called a recommended local dealer after this initial drive and described the problem. They at first said that their "water specialist" was not in until next week, but I pressed wanting to bring it in the same day so that they could at least inspect it to see if the water inside the roof was going to be problematic. I took the car in 2 hours later and the tech confirmed he heard water in the roof and that the headliner was wet. He asked me to bring the car back the following morning to drop off (I could not leave it that day). He said they would need to check the drain pipes as those were likely the problem.

3. Brought the car in the next morning (yesterday - Friday). Received a call Friday evening from the service manager saying that they could not find a problem with the drain pipes or leaks from the closed sunroof. He only talked about the carped being completely soaked. I asked about the water in the roof and the wet headliner, and he was unaware of either of these things and said the tech I saw previously was not there today. I explained that I brought it in for these 2 issues and he said the headliner was dry and he hadn't been told about anything other than the interior being wet. I explained again what I'd told the tech on the first call and visit, and confirmed for the manager that our street does not flood (he was concerned about the car having been flooded) and that I had not left any windows/sunroof open during the rain. He said that until they find a leak they could not say that it was a warranty issue, but that they would definitely need to rip out the carpet immediately to replace the padding before it molds. He said the water in the carpet was very heavy.

I am not sure what to think -- I've heard of others having water inside the cabin, but usually from clogged or disconnected drain pipes. What else should I be asking about? Are there other causes I need to be sure they check or common flaws to be aware of?

Thanks

There are not any common flaws that I can remember hearing about. In my professional experience the most common issue when you have such a leak is from the drain tubes (pipes) that you have mentioned. One of the problems we use to see was that they would become clogged, especially from leaf fragments and that would cause them to become blocked. Then a dealership guy would try to unplug them by blowing compressed air through them. With a clog this sometimes caused the tubes to be blown off their connections which then allowed water to leak inside the roof liners.

Cars with factory moon roofs are made with a steel lip so that its difficult for water to leak anywhere unless there is a problem with the drains or the drain tubes not flowing. Of course anything is possible and there are other things to cause this but the moon roof is the prime suspect.

Talked to the service manager again this morning.

Here is the update, which has more surprises:

1. Most (to me) troubling issue first - the tech who I saw on Thurs did not confirm to the manager that he saw any water in the headliner or heard any in the roof. Which is the opposite of what the tech told me. I communicated to the manager that this was very concerning because that is what I took it in for and the tech told me the headliner issue was obvious.

2. The floor: the water appears to be coming up from underneath the carpet because the padding is soaked but not all of the carpet is wet. On Saturday I could feel that the carpet on the driver side was wet but not anywhere else in the car. The manager said they have now removed the seats and pulled up the carpet and the padding is wet throughout the car, but only the actual carpet on the driver side. This tells him it's not an issue of water coming down into the carpet. They will have to replace the padding (and carpet? not sure).

3. There is also a very small amount of water inside the center console. Not enough to soak my belongings, but enough for them to see on the bottom, almost like a sheen of water.

4. Relieving my stress the most: there is no evidence of flooding. They found no flood lines and no other markers indicating that the car was flooded. Which is great because it wasn't.

5. They found no evidence of a windshield leak.

6. They have thus far found no evidence of a sunroof leak, nor evidence that the sunroof was left open during the storm. Also great because it wasn't.

7. What's going on now:

- Manager is calling American Honda to get, basically, permission to take EVERYTHING out of the car (all carpet, center console, whatever they can strip down) and do another water test. He said it's clear water is coming in some way, but they do not know how yet.

- They are also going to check the AC drain, but said problems with this usually appear on the passenger side first.

- Since they haven't taken apart the car yet, they have not checked the length of the drain tube from the sunroof. They did confirm that water is flowing out of it correctly but will need to confirm that there are no punctures in the tube.

- There is no timeline for when I'll have my car back.

- This is currently a big mystery for them.

(I originally posted this in the incorrect forum, so I am rewriting and posting here instead)


My 2014 CRV EX-L w/ sunroof appears to have developed a water leak. It became apparent after a heavy rain last week week. However, the dealer I took it to (have never been there before) is having trouble figuring out where the leak is and/or how the water is traveling.

Background:
Heavy overnight rainstorm last Wednesday night. When I got into my car the next morning (it is parked outside), I noticed that the headliner on the driver side was soaking wet near the front between the window and visor. When I began driving, I could hear water sloshing in the roof on the driver side. It was most apparent when I sped up to 20+ and then braked to a stop. I didn't check the floor for water. Took the car to a nearby dealer the same day and the tech confirmed he heard water in the roof and that the headliner was wet. He asked me to bring the car back the following morning to drop off. He said they would need to check the drain pipes as those were likely the problem. Took the car to the same dealer Friday and left it.

Received a call Friday evening from the service manager saying that they could not find a problem with the drain pipes or leaks from the closed sunroof. He only talked about the carpet being completely soaked. I asked about the water in the roof and the wet headliner, and he was unaware of either of these things and the tech from the previous day was not there. I explained that I brought it in for these 2 issues and he said the headliner was dry and he hadn't been told about anything other than the interior being wet. I explained again what I'd told the tech on the first call and visit, and confirmed for the manager that the car experienced no flooding/sunroof was not left open.

Dealer's plan for the weekend/Monday was to rip out the carpets to prevent molding.

Saturday I went to check out how wet the carpets were. Confirmed that the driver side carpet was wet to the touch and did not feel any wetness on other areas of the carpet. Headliner had dried. No work had started.

Update from call with service manager Monday morning (today):
1. Most (to me) troubling issue first - the tech who I saw on Thurs did not confirm to the manager that he saw any water in the headliner or heard any in the roof. Which is the opposite of what the tech told me. I communicated to the manager that this was very concerning because that is what I took it in for and the tech told me the headliner issue was obvious. The manager did not dispute that the headliner was wet, but said the tech did not confirm that and has it down as reported by me.

2. The floor: the water appears to either be coming up from underneath the carpet because the padding is soaked but not all of the carpet is wet, or at least flowing into the floor in a way that it hits the padding first. The manager said they have now removed the seats and pulled up the carpet and the padding is wet throughout the car, but only the actual carpet on the driver side. This tells him it's not an issue of water coming down into the carpet. They will have to replace the padding (and carpet? not sure).

3. There is also a very small amount of water inside the center console. Not enough to soak my belongings, but enough for them to see on the bottom, almost like a sheen of water.

4. Relieving my stress the most: there is no evidence of flooding. They found no flood lines and no other markers indicating that the car was flooded. Which is great because it wasn't flooded, and also great because that would halt any work until insurance was factored in.

5. They have found no evidence of a windshield leak.

6. They have thus far found no evidence of a sunroof leak, nor evidence that the sunroof was left open during the storm. Also great because it wasn't left open.

What is going on now:
- Manager is calling American Honda to get, basically, permission to take EVERYTHING out of the car (all carpet, center console, whatever they can strip down) and do another water test. He said it's clear water is coming in some way, but they do not know how yet.

- They are also going to check the AC drain, but said problems with this usually appear on the passenger side first.

- Since they haven't taken apart the car yet, they have not checked the length of the drain tube from the sunroof. They did confirm that water is flowing out of it correctly but will need to confirm that there are no punctures in the tube.

- There is no timeline for when I'll have my car back.

- This is currently a big mystery for them.


I am looking for insight on:
1. Anything beyond drain tubes and windshield I should inquire about for the leak

2. If an AC leak could end up in the headliner (I don't think so) and if an AC leak could produce enough water rather suddenly to soak all the floor padding

3. If there are any other examples of water leaks from either rain or mechanical issues that sound similar

4. Any thoughts on the timeline thus far and other questions I need to ask


Thank you

I recently noticed a large water spot on the headliner over the front passenger grab bar. My headliner throughout the remainder of the vehicle is clean. The window was not left down during rain, neither was the sunroof. Where could this water/moisture be coming from? If anyone has ever had this issue, or one similar, please give me some insight on the resolution

I used weed eater string to snake out the drain tubes and it works excellent. Take bottle of water and do a drain t st after you snake them out. Also compressed air thru a small hose can clear blockage.

I have a 2015 CR-V and I am also having similar issues with the headliner water stains. Rarely is anyone ever riding in the back seat, but I noticed one day when I was lowering the back seats that water stains were were highly visible on the ceiling. There was a water ring around the back seat driver side seat belt area of the ceiling. Also, the pull handle on the passenger backseat side had a water ring. I have no idea where it could have originated, and I noticed there were no water stains near the moon roof. My original factory warranty has expired but I purchased an extended warranty with the same coverage from Honda Care through the dealership. Here are some pics, and they look terrible. I need to get into co tact with a local dealer next week to have it checked out.

Hi, I had the same issue on the B pillar, passenger side. water keeps leaking in and staining headliner after a fairly heavy rain.
car is a 2015 CRV, no moonroof.
dealership i bought it from (used) did the first repair for free, but could not find the leak. Put extra sealant around the bolts in the roof rack track.
It leaked again even more about 6 months later or so, and they wouldn't repair it again without charging me. I took it to another dealer, who said they have seen this before, knew how to fix it and did so...at a cost of over 900$ canadian. I will contact Honda Corporate to sort this out. Any news in your situation?
