Check the drain lines from the sun roof and make sure they are clear. There are four drain lines at each corner. You can easily get to the front one. The rear two drains are a different story which requires pulling down the head liner. The seal around the glass does not actually provide a water tight seal, they just slow the flow down. The drain lines keep the water from building up in the channels and leaking into the cabin.
The seals on the side windows again are not intended to be water tight just reduce the amount of water. There are drain holes along the bottom of the doors and need to be clear to allow the water to drain.

 

Thanks for reminding me
Have you checked the drains under the windshield, above the firewall?

This was ours today, plugged with leaves and dust

Sucked it clean then blew through the drain hole with compressed air.

Not sure if this would overflow into the interior, but it is in the right area
Cheers!

 

You might want to pull back the carpeting, You might see old water marks which can help indicate where the water is running in from.

 

I strongly suspect that you have a plugged sunroof drain, this is VERY common. There is an easy way to check this, open the sunroof and pour a cup of water in the drain channel and see if it quickly drains out, you should also see it running out onto the ground.

 

Thanks for the replies everybody. I'll check those drains.

 

If they are clogged, you can try a length of weed trimmer line run thru the drain.

Don't use compressed air.
If this doesn't turn out to be your problem, check that the drain holes on the bottom of your driver's side door are clear.

 

Update. The water seems to be flowing well from the sunroof frame to the ground through the drains and from the base of the windshield to the ground. I poured some water on the sunroof frame and sprayed water with a hose to the windshield.

I guess the rain was just too heavy for the drains to keep up. It was an extraordinary storm that got flooded many areas of the city including the airport. However, the other cars in the block didn't get water in, so it has to be something else. Maybe the leaves accumulated in the base of the windshield, combined with the heavy rain did it.

I will leave it dry before putting the panels back on and wait until the next rain to check again. I will blow the leaves more often too.

 

Some have reported water coming in around the door seals.

 

UPDATE: It's been a month since the big rain and I thought the problem was solved, but last week another heavy rain left some water on the driver floor, not as much as the first time, but still enough to need attention.

So I removed the mudguard inner black plastic trim on the front left wheel and I found a big bunch of leaves that accumulated there throughout the years. I bought my car 10 years ago and I always park it under an oak tree that drops leaves all year round. Most of the leaves usually accumulate on the base of the windshield, but some make their way between the mudguard metal panel and the black plastic trim.
I cleaned everything on both sides. The right side was as dirty as the left one. I hope this will solve the problem.

 

If you didn't do it already check in the wheel well for the sunroof drain exit. Then run the water accordingly. Passengers side on my daughters had all the leaves like that and other junk still blocking. I used my shop vac at the drain and pulled some junk through. It was like a big plug and all of a sudden flowing quickly. The drains have a 90 degree turn inside so even the weed trimmer line won't get all the way.

I did the drivers side the same way just to be sure and that had a lot of junk also.

When done I vacuumed the carpet padding real well with shop vac. I then rented an industrial dehumidifier from Home Depot and closed up the car (tube ran outside). I collected over 1/2 gallon of water with that. That was after close to 1/2 gallon from just shop vac.

Here was the thread with pictures The small black grommet next to cable is the drain, same place on passenger side. On the inside its the blue line with black elbow.

 

UPDATE: Water inside again.
The leaves were not the problem, or at least not the whole problem.
There was some rain lately, but nothing exceptional.
Carpet on the driver side was again wet, front and rear. More on the front. Passenger side was dry on both front and rear.
I will check the drains again.
I'm thinking in taking out the wipers and the trims under it. Not sure how difficult that is.
The spare wheel well is dry. The problem is in the front.

I wonder if water from the windshield wipers sprays pipes is somehow leaking inside.
Or maybe condensation water from the AC system?
Does that make any sense?

 

Hi @Mariano, were you able to trace the leak?

We have the same scenario. I've been tracing the leak for weeks, but maybe the source may differ to us. Try to check your hood release cable under neat, there is a rubber on the car's fire wall, rain water might be flowing through that cable. I have read that from other page, and check mine also but with no luck.

 

^^ Thank you very much. I haven't got any water since the last update. I checked after every rain. I will do the hose rain again and check the hood cable.

 

Has the windshield ever been replaced?
There have been many reports of water leaks in vehicles that have had their windshield replaced due to improper sealant/adhesive application. If there is a leak on the side of the windshield the water will leak down behind the trim where you can't see it and end-up on the floor (either side). If you purchased the CR-V used and don't know, look at the windshield's left lower corner and see if it says Honda on it. But, even if it does say Honda on it, the windshield may have been replaced.

 

^^ Thanks. Not that I know. I've owned the car since 2013, when I bought with 20k miles. I'll check if it says Honda.

 

@Mariano so i was able to give time to check the car, before typhoon days arrive, and found the cause of leak inside the floor mat driver side when it rains

I remove the splash guard/mud guard/plastic covering (see pics) and found inside this 2 groumet and hood release cable which has a crack due to heat. I put a silicone on the rubber of the hood cable, and cover the 2 groumet with butyl tape. Just after a few minutes, it rain so hard for 30mins, and after the rain, I've check my floor mat, it was very dry!!

So I waited for few days, rain comes again, that hard, I can say that I successfully did a good job, no more leak, no more wetness. Hope this can help you out

 

^^ Thank you very much. Good job finding that one!
I checked the hood cable on mine and didn't find any crack or hole.

I got some water inside after last heavy rain, and it was very close to the driver's door, so I suspect the door drains or the door weather strips. I have to pull out the driver's door panel and see.
I also suspect that water comes in only when the water is pushed by the wind from the driver side. That would be the reason why water gets in only in some storms and not in all of them.
