Hello all! If this video has been any kind of help to you, I would really appreciate it if you would subscribe to my channel. If I can get to about 1000 subscribers, I believe that makes me eligible to get a little add revenue from KZfaq, which will help me make more videos! Thanks so much!

I am surprised there isn't a case action lawsuit against Honda

3 years later and still relevant. This led me to the problem in minutes. My 08 Fit is all cracked in there. You're a fucking champion!

Just bought an 07 and dealer didn't disclose a leak. So literally driving off I hear water sloshing and there it was water in the tire well. Glad I came across this video.

hello from New Zealand. My daughter has a Honda Jazz & has the same issue. Funnily enough Honda New Zealand as also about as much use as a chocolate teapot on a hot summers day!! Thank you for sharing and you've saved me from the hassle of putting a video up on KZfaq and hopefully I've helped you get one subscriber closer to the magical 1000 subscribers. I'll also let other Honda Jazz owners know about your channel.

Thanks heaps. This fix worked very well for my 2006 Honda Fit in New Zealand. The tyre well previously always had a puddle in it. It's now been dry for months after the fix. I used basic clear silicon.

Thank you so much for this video. My GD3 had a crack in the same place leading to water in the wheel well. I spent < $20 on a can of flex seal and after a couple more rainstorms my wheel well is still bone dry.

We didn't notice the water. But we noticed when we opened our car after one week of not using it and it sitting in the hot, humid environment. The entire backseat was riddled with mold! We had a professional come out and do a deep clean that solved the mold problem--actually made it cleaner than when we first got it! But then we had to figure out why there was so much water in the trunk and backseat floorboards. Then we found your video! This is exactly what our Fit is doing. We had had extreme amounts of rain that week--that's why we didn't drive the car. So thankful to find your video and apply the solution.

If you go to any outlet that sells car body panels they should stock an item called .. "Seam Sealer" it was actually developed for marine use but was also taken on by the body repair world, you can get it in tin form so you can brush it on or in a similar type tube that would normaly be used for bathroom type sealant .... its the best stuff to use...... And for those who have the leak problem.. dont worry about it... its water.. its coming in somewhere which means it can be found and fixed. :)

Thank you. A very clear description and solution to this problem. I have a Honda Fit (it's called the Jazz here in the UK) and it leaks into the trunk. Someone has used some RTV to seal it but they've done a bad job. The dealer who sold me the car said someone washing the car had 'accidentally spelled some water in the trunk' but they would dry it out. I didn't know this was a problem until the first big rain storm arrived and I could hear the sloshing. I contacted the dealer but they didn't want to know. Anyway, I am preparing the car for sale and this is an issue to fix. Thank you for your video.

OMGOSH thank you for this! My daughter has a swimming pool in her trunk and back seat floorboards. Geez Louise. This car has been in the family (my 2 sisters owned/passed it down since it was brand new, 2008) and I was hoping that it would last a while for my daughter. Thank goodness for carpet shampoo machines, because mine has been getting a workout. THANK YOU SO MUCH FOR THE DETAILED VIDEO! I can’t wait to work on getting the car permanently dry today!

You have made it very easy to understand whats going on regarding how the water is getting in. Regards from a grateful Honda Jazz Sport owner in the UK 👋☺

Thanks for posting, my spare wheel would have been floating if it had not been bolted down. Fixed now thanks to all your hard work and some plumbers gold sealant. Nice one I owe you a beer

Thanks ... never would have guessed our leak came from those cracks ... but your great vid helped us find and seal them.

The most helpful guide on KZfaq. I scraped all the old sealant out, which was dry and brittle. I then used Sikaflex sealant adhesive to fix it. While the water ingress is greatly reduced, I do need to do a bit more.

I have had this issue for years and now with the last month of rains here in Kingston, Jamaica it is showing up the worst, Thank you so much for your video.

Hi from Wirral, UK. (Independence since 11pm last night. 31st January) There's a Honda Jazz in the family which has the same problem. Have been informed rainwater gets in through the rear lamps. Your video is very informative. Thanks for posting. Have silicone sealant-will check it out.

So very insightful. I am about to fix up my Honda Fit to stop that dang water leak into the trunk. This video is a lifesaver!

Thanks for posting this. We have noticed water in the back for a while and using your video found the cracks and sealed them. It rained all day yesterday and we just checked the car and it is dry. Thanks again.

Lol I wish I checked my boot before I bought my 2004 honda jazz 6 years ago. Eventually I had 4 holes drilled to let the excess water out. It worked...its as dry as a whistle now and I'm still driving it. 5 minute job done!

Thank you so much for this! I Just purchased an '07 fit last week and have water in the spare tire area. You saved me a whole lot of time searching for the source!

Thank you so much for this video! I have just fixed the water leak in my 2007 Honda Fit, spending only $13 for a tube of Flex Shot clear sealant. So pleased that my leak problem is solved. I only wish I had found this information years ago. :)

Had the same leak in a 2005 Honda Fit, with the same cracks in the waterproofing! Thank you for sharing!

I've done it in 2010:) I could repeat every word you said about this issue. I found a blog post from British Jazz owner, who repaired this issue on his 2001 Jazz and repaired my!!

Man dude I had this same issue and just figured it out myself. I wish I would have seen your video last summer! I went to the dealership and they said they had no idea what was wrong, of course. I came across the exact cracks you did. I hope others can figure this out quickly as well!

Cheers for this. Had a downpour the other night and noticed the smell of death in my car, thought it was the frozen meat I'd left in the back the night before but no, must be a gallon of water in the tire well. Watched your video and saw the two big cracks all the way down the caulking on both sides. Filled it full of Shoe goo, finger crossed no more involuntary swimming pool. Thank you!

I ended up filing a Vehicle Safety Complaint and I advise everyone else with this issue to do the same, hopefully it will draw attention to the issue and push a potential recall if needed.

You saved me so much grief! Such a simple fix! Mine was overflowing and leaving standing water in the backseat. SO MUCH GROWING MOLD.

Brilliant, I had exactly the same problem on my 2003 Honda Jazz (Jazz in the UK) and couldn't work out where the water was getting in. Your video took me straight to the source of the leak and I have exactly the same cracks on my car. I've sealed with silicon and fingers crossed that'll sort it. Thanks very much

Thanks for making this video! We have a 2008 Honda Fit and discovered water pooling in the trunk. You definitely saved us time in diagnosing this problem.

Thank you for posting this! I have a 2008 Fit Sport...exact same problem. Your video will make it easy for me to at least try and resolve this issue that Honda won’t fix.

Great vid!! I live in the Netherlands and we call it a Honda Jazz - they do have the same problems. Let’s hope this is the solution.

Very well presented. You did a great job with the camera shots, tracing the entry of the water and identifying the problem I was about to do the same diagnostic today as mine has water from yesterdays storm. I don't have a lot of water in the boot but that's nice to see. I've had other cars where there's been swimming pools in the boot spaces. This one looks to be quite an easy repair. Bit fiddly without taking the rear door off, but possible, Thank you for your effort, subscribed

Thank you so much for posting! My Fit has the same problem...

Thanks for sharing this. Big help! I'll share this with one my coworkers who's having the same problem with his.

Thanks for taking time to show ,mine fills up with minimal rain.i just vac today ,week ago same.also get rear driver side carpet wet .

Thanks for this video. It helped me sort out my Honda Fit's water leak. My fix isn't pretty but it will do.

I had a friend get a flat tire which reminded me I needed to check mine. The bottom of my jack is ruined from sitting in water. Thanks so much for this video! Hopefully this will solve my leak!

2006 Honda Jazz GD in South Australia, 39,000Kms. Car has been housed mostly outside, very hot dry summers and very wet winters. Noticed a few months ago car was smelling, passenger carpet behind driver soaking wet. Found the boot full of water, bailed out over 12 litres. Checked roof rails, good condition, no rust but filled up with pollen and grime from trees. Cleaned roof rails. Took it to Mechanics shop who work on a lot of Honda Jazzes. They had it for 2 days. They spent a lot of time investigating, they removed some roof lining, they sealed the seams on the top at the back, as this video. However they had to admit car was still leaking. I saw rain coming the other day, so I sat in the car for a few minutes. Ive had the boot lid strapped up to the back headrests for weeks with the back seats up. After a few minutes, I was able to see that a leak was coming from rear passenger door, running down the black plastic sill and then seeping into the carpet. If you put your finger in where the back seats lock in, its very wet. I noticed the other rear passenger floor was slightly wet where the seat locks in, although I could not see a run line on the door sill. I believe this means the door interior has to be removed, and it could be a bit of plastic type paper that has failed, easy fix with a bit of heavy duty adhesive tape. After the rain, I opened the hatch, I could see a small run of water on the plastic at the back of the rear lights, running to the boot. I popped off the triangular cover and there was damp in that area. I noticed there was a rust line on the boot floor from the rear light area running towards the passenger rear seat, especially around the nut where there is a ring pull to remove the fittings around the boot. I had suspected that water was coming in the rear lights and suggested this to the mechanics shop. I spoke to Honda Head Office in Melbourne twice, they said have the car examined by a dealership. That dealership said it was best to go to a Crash Repair Shop as they are the ones to find leaks. Talking to an ex Honda mechanic, not in the business anymore, he told me to re-seal the rear lights, a known problem. He seemed to think it was only 2006 models, I told him Jazzes leaked like sieves. I under the rear lights gasket in time flattens. I believe this to be the problem. Unfortunately, for 2006 model the bumper has to come off to get the rear lights off which is a bit beyond me. Another Honda mechanic told me to keep the Jazz gasket and silicone either side of it, so the gasket is the sandwich. It was a wet day today and windy so not ideal to be working on fixing leaks. At the moment, car rear lights are masked up with ordinary masking tape until I decide next option. My season is a very wet and coldish Spring at the moment. When I first had the problem, I dried the carpet by heating a largish wheat bag very hot in the microwave, I laid this on several sheets of newspaper in the rear passenger footwell. The weight of the wheat bag pressed on the newspaper which soaked up the water. I also put a couple of other heavy items on the newspaper. Changed the thick wad of newspaper several times. Eventually, it dried without smell. I heated the wheat bag every hour or so, to me this was better than mucking around with a hairdryer. On days it was fine, I would leave windows open and hatchback open. Will update on re-sealing the lights and removing the interior of rear passenger door.

Many Thanks. I just wish I had checked sooner. Always thought it was the gas sloshing around. Nope, just a lot of H2O. Fixed it. Many thanks

Thanks for the post! I have the same year and even the same color fit. I did buy Flex Seal spray (clear) Pryor to finding this video. Wish me luck!

Excellent, thank you for that information, I have got the same problem with my Honda including the smell.

Thank you! I would have never looked on top and I'll try to remove the insulation, which is probably moldy! Very helpful!

I used the flow able silicone that you use for around windshields to fix windshield leaks on those cracks and it works great I did it right when I bought the car and no issue since

Old video but thanks. Mine was bad, and I let it sit a month… bad choice. I pulled the plastics and saw one little streak and traced it back to the same cracks you showed in the video. I’ve just been parking in garage, been too lazy to buy the silicone.

wow! this is my exact car (color and all!) and I had no idea where to start. thank you!

Found the crack pretty much where you suggested! Good video many thanks

0:41 its been tormenting for months finally found out there’s an ocean in my boot

Thanks! Same thing happening to my 2015 and Honda was trying to charge me $300 to fix. Going to try this first.

Thanks for this great video! Used a toothbrush and Permatex 81730 Flowable Silicone Windshield and Glass Sealer to repair it first attempt. NO water! Thanks again!

I'm currently looking into the GD Fit as a future track car and have been looking for possible issues that I may need to fix, thank you for sharing this info!

Thank you so much! Finally we’ve got a dry boot. Amazing

Thank you very much for your video! Very helpful. Our 2007 Honda Fit was swimming in water!

I thought it was the rubber seal never imagined it was the metal. Thank you.

Thanks for video! I had same problem plus leakage from driver tail light (water was accumulating between gasket and metal part on lowest opening for fog light. I ordered new gaskets and hope they will keep water out) and from small white plastic pocket for tail light pin (sealed it with sikaflex) both dripping down to spare tire area.

My son's 08 Fit had water on rear passenger floor and when I found this video I looked in the spare tire well and found 1.5" of water. Also found the same cracks and after cleaning, I repaired them with Aquaseal which is a clear urethane sealant that sticks well and self levels before it hardens to a tough flexible surface. I have used it to repair wetsuits with a lot of success. Hopefully this will solve the problem. thanks for posting the video.

Thank you sir for your post! I THINK this is going to help me on were to look for my leak on my crv wetting my head liner!

Great information! Thank you very much for posting this. Recommend 3M 41594 Polyurethane Sealant 540 for this repair (even though you'll end up using only a small portion of the cartridge content).

Spencer Strickland - you are my hero (for the moment). Great video. I have the same model, experiencing the EXACT same problem(s). Now I know what to do about it. It really sucks that Honda has turned a blind eye to its loyal customers - your video has almost 10k views!!...this is not an isolated problem! (I smell class action! - is there a lawyer in the house?)

I have a 2007 Honda Fit doing exactly that. Thanks for the video.

Very many thanks for this from the UK, my Wife's Jazz (The UK name for the Fit) has the same problems which I now have a thought about how to deal with.

Thanks for your video. Wife’s car had same problem. Nice easy fix👍

Thanks for sharing 👍🏻.same issue with my civic..your video solved my problem.many thanks 😊

Thanks for showing those small cracks. I just got a 19yr civic which started leaking this after after a couple shit load of rain showers. I was looking at the rubbers but I guess I need to hunt for small cracks as well

Really useful video, thank you. I've just bought a 2011 Jazz and there's water puddling on the parcel shelf. I need to investigate further and repair.

Thank you so much for this video! 15 bucks in materials will get rid of the swimming pool in my trunk!

My Fit had so much water, this morning when I braked, the water rolled forward and flooded the floor under the back seats. Thanks for the video. I will be using 100% silicone caulk around the seams you showed us.

This is what I love KZfaq for. Thanks for taking the time buddy. Subbed

Thanks for your video and talking through fixing this problem.

Thanks for sharing your experience!

i had this issue too, on the join panel.. i'll try the way you fix it... thank you for the information..

My 3rd gen is having water pool on the same area. Thanks for the video. I'll check these seals

thank you for the straight forward easy fix!

My 2008 Suzuki SX4 hatchback had the same problem! Thank you!

Thanks for this - really helpful.

Thanks for this video I checked my bottom thing because of the video and it was full of water, my jumper cables were inside dirty black water… went right to Walmart and covered those cracks with RV sealant

Thanks man, my 93 Civic hatchback is leaking from the back hatch. I think this will help.

Thank you for sharing. I got one side of rear seat floor wet in the winter and I couldn't find water trails so far. I have also tried to apply some silicon glue to the join parts but not yet sorted out the issue. Very strange.

Brilliant video ! ,thanks for the help ( UK honda jazz/fit owner) 10/10 :-)

Just had the same puzzle with a 2007 Fit in Gatineau Quebec - dealer played stupid. Last time I will be taking any business there.

You can use dry ice to freeze the sound-deadening and then smack it with a hammer to remove it. That mold doesn't look like it will be coming out.

It’s almost the end of the 2022, but this problem still goes on. I hope this 5 year old video could help me out, imma try this one later this week and i hope i don’t forget to write down the updates

UPDATE January 2022: I had used Permatex to seal all possible seams. Still good and dry inside! Here I am August 2020 and I decided to have a look in the hatch (mine is a 2008 Honda Fit) cause I thought something was rolling around. Oh man, all this rusty water was accumulated around the spare tire! Just awful Must have been a problem for YEARS cause I did notice a general musty smell in the car. thinking it was just a lousy HVAC system. So I found a problem I never knew I had. Thanks for the helpful video.

I have the 2016 Honda Fit and I have the same problem. Mechanical wise, the car is very reliable.

You sir are a legend! Thank you so much, really helped!

Think this solved my problem with my HRV, too! Experiencing the same problem and thinking this will solve it. Makes sense, they're built on the same platform.

Thank you so much me and my husband try to find out where it was coming from because on the days that rain it will make our back passenger side floor wet but no where else besides where the spire tire is and we have been stressing out for about two months now we do have a 2008 Honda fit but we love our car even tho the leaks

Thanks, we have 2 Jazz's (UK) a 2004 and a 2005 and they both do it the newer one reallt bad, 4 inch on water last time, I'll try what you've said thanks

Great Info, Now i have facing this issue on my Honda Fit 2007 (Silver Colour) . Let me fix it . Thank for your posting!

Thank you! I’m currently having this same issue along with water getting to rear right passenger floor whenever it rains.

Thanks man. My Acura MDX is doing the same thing

THANKS. Same problem with my 2007 Honda CR-V.

Ps aren't scared of trappibn in moist, it will start rusting. I'm glad I live in Caribbean where it hardly rains..but nowa season has started where it does rain more then usual so thanks again for showing to look for cracks as well

O meu Fit 2006 está com o mesmo problema, vou por algo a base de silicone também, obrigado pelo vídeo. Saudações 🇧🇷🇧🇷🇧🇷

thank U for the video i had got the same problem , i have fixed this but my question is : did the water also runs to the inside of the back fenders ?? becouse i dry everything but i didnt check down there ??

Thank you so much I have subscribed out of gratitude

My fit leaks too. Gonna see if this is the issue. Very likely thanks

Same here in Portugal

I did notice my rubber seal is folding inwards so think rains gets through when it's really pooring like hell. But the leaking is more at the top, not near that seal issue. So must be something like a crack or so

Thx I learn a lot I have a problem after car wash or heavy rain big puddle in boot 👍🇬🇧
