Honda Jazz Water Ingress
Вставка

- The well known problem of water ingress into the wheel well area of the Honda Jazz/Honda Fit generally has a fairly simple solution.
I'd performed the usual fix of applying sealant, to the roof channels and upper rear hatch area without successfully stopping the water ingress.
The leak is under the rubber roof trim just above the damper brackets. The factory applied sealant cracks and very slowly lets water in, thats why it's difficult to find.. Lift the trim and dig it out about 4>6 inches of the old sealant and redo with silicone sealant. A 3mm hole drilled in the floor either side of the spare wheel bracket will drain any other ingress. As you saw it was dfficult to find where the water was getting in so large accumulations usually take some time to build up. The little drain holes will stop this and a good spray around with water repellant will stop the rust. That's how I did it anyway.
Hi Golem, it's a strange one with this car. The first Jazz we has was a really easy fix. Just sealed the rain channel area behind the back hatch and no more problems. This one is more troublesome but I'll try putting some additional silicone under the black trims.

Thanks for the comprehensive investigation, my 2003 se sport was leaking for years until recently i siliconed the roof rail channel and some cracks on the side of the boot lid hinges. Its all dry as a bone now but another totally different problem came up when my Catalytic converter disappeared overnight :(
I've been reading about the cat thefts on a couple of forums, quite shocking really at the number of people reporting that problem. So far, the boot seems to be completely dry - I really can't believe that the nick in the seal was to blame for all of the water ingress! With the first Jazz it was solved easily, this one really had me scratching my head.
@@gtd65 I will be installing an aftermarket Cat soon but am anxious the lowlifes will come round again on my driveway, do you have or recommend any CAT. protection on your car?
@@stevelee838 To be objective, I think any measures you can put in place would easily be overcome by a motivated thief.
I was going to link to the clubjazz forum for help but see that you've already put a post up regarding this subject.
Would it be possible to install a CCTV recording option or a very bright pir led if this occurred at night?
@@gtd65 Thanks for your suggestions, I will probably install both and even attach some wire cable and clamps to the cat itself
@@gtd65 mines a 2006 and it has a big leak will a new seal fix it? Thank you
My wife's Jazz is a 55 plate version and has just begun to exhibit this problem, my own 56 plate version had it - and may still have as I sold it a couple of years ago. Makes sense if the door rubber has started to go, perhaps capilery action draws the water in with the door seal fitted but doesn't have the same effect if it aint there. Thanks for the useful investigation which backs up many US you tubers problems with the Fit (The US name for a Jazz).
It's a peculiar one, as the previous Jazz that I had a go at, on an 02 plate, was fixed immediately by applying some Hammerite paint to the joints at the rear of the roof channel. Great little cars otherwise but tonight I need to change some brake pipes and fit a new drop link.
Brilliant videos but oh Gavin I wish we'd had your You Tube info 21 years ago when I had my first 2002 Honda Jazz! It was a 3 month old Honda Dealer's forecourt car and I had lots of problems with leaks which only became apparent just after the warranty had expired...of course! Honda were no help. However, when I bought my 2007 Jazz, again a Honda dealer's forecourt car ,which I still have and love, there were quite a few forums etc mentioning leak problems which again occurred in mine but my wonderful garage guys, who used to work for Honda, were brilliant at fixing them. However, that was many years ago, until now March 2023, when I have just discovered a pool behind the driver's seat but very little in the boot and none in the wheel well. I'm pretty certain it's the roof seal probably due to the age of the car. I would do it myself but I am now 80 and still have my wonderful mechanics who are going to fix it. In spite of the leaks I love my Jazz, it's like a Tardis and hope that this one will see me out!! However, thank you for your videos they are so helpful but would have been very useful all those years ago!
Hi Sheila, thank you for the positive feedback and I hope you manage to track down the source of the water ingress soonest! They are cracking little cars indeed and very much Tardis like 😀
So two possibilities on my recent experience with a 2006 model. It could be the vapour shield behind the door cards needs resealing. Or the door seals are saturated at the bottom and water is squeezed inside and trickles down soaking the carpets. The seals have several drain holes a foot apart. I made some more 6 inch apart at the bottom. I could see these areas were saturated when inspecting. I always inspect after rain , open doors and wipe away any excess pooling on the door seals. This works for me. I've had the car 3 months now. The first month was a real pain as I tried to find and fix the leaks with no garage. It's been just as wet since but I've got it sorted. Had both rear door cards off twice. Second time I used the black RTV sealant as clear silicone didn't work for me. I use a liquid rubber protector on the door seals once a month but the additional drain holes I made have made the difference.
My cat was stolen two weeks ago. $850 for the repair. Chicago, IL. Great video. Thanks.
That's not so good, you can get pattern cats here for a fairly low price but not sure of the quality.
The salesman was right, "they all do it"
To quote a wise man, "not a Yaris owners problem"
Whilst they can't hold a candle to Toyota build quality, they are a more engaging car to drive, and offer class leading usability.
@@MrWilliam.Stewart it's something you'd think would be fixed by Honda.
They are very practical cars and as you rightly point out.
I think the only other problem with these cars is the input shaft bearing?
Otherwise, fantastic little run arounds 😀
@@gtd65 Yes, infamous for manual gearbox input shaft bearing sometimes being made of cheese, again "not a Yaris owners problem" but the Jazz is such a good motor vehicle once it's manufacturing flaws have been mended.
Own both a first gen Jazz, and second gen Yaris. The Toyota has proven superior when it comes to component durability and low cost of ownership. The Jazz has proven superior for everything else.
Bought a 2006 Jazz a week ago. Strangely it has a cut in the boot seal same as yours. I suprrglued it back down. Also used clear silicone on the plates at the top of the tailgate. Not checked under the roof seams yet. Just trying to be proactive. Bit of water there where the jack is stowed beneath the damaged lip. Also a common problem on my Citroën c1. I have put sealant round the tail lights. Always have the plastic plug in the wheelwell out on the c1
JC, coincidentally, there was a fair amount of water in the back of this car at the weekend. Looks like I'll need to have another look! With the first Jazz, it only needed looking at once and no more water ingress.
@@gtd65 Lashing it down here. Rear paasnger side windows tend to mist up also. Experimenting with the best AC and blower set up . Any tips? I will check the carpets and boot tomorrow
@@JC-hu1wd Yeah still raining here and a bit on the windy side. Ripped the felt off one of my shed roofs too! Boo! I think the best bet is to make sure the seams inside the back door are sealed up as well as the last few inches of the rain gutter, initially. I really didn't understand why there was no water ingress with the boot seal removed....
Sealing the roof gutter and back hatch seams solved the 2002 car first time and it had really bad water ingress.
@gtd65 Update I checked boot this morning and still water where the jack is stowed below the boot lock. So put my hands down and round inside where the central plastic trim is. Foam pads saturated at both left and right. So I unclipped the trim by the lock and popped it off. What I found was damage to the plastic trim at both ends about 1 cm broken off at both ends. Someone must have levered the plastic trim off with a screwdriver in the past. I'm sure this is where the water gets in. So silicone it where the gaps are and along the seal by the lock.
@@JC-hu1wd The rain stopped here late afternoon. I'll try to get a look at the car tomorrow, if it's not being used. Thanks for your latest update.
I've been on a similar journey with my leaky jazz, I eliminated all the usual suspects but still have a tiny bit coming in on the right rear, I've drilled a couple of drain holes and that's stopped it collecting so job done as far as I am concerned. I also found a crack in the roof guttering on the front passenger side which explained the front soggy carpet Regarding the cat thefts I'm going to replace my original cat with a pattern part to remove the appeal to thieves, they'll take on look and not bother as pattern ones are worthless as scrap. I'll sell the original for circa £300 and treat myself to something nice
You've certainly had a few issues with water ingress then! Sounds like a plan for the cat replacement. Seems mad that they sell for so much when a new pattern item is so cheap on eBay?
cat converter wise, I thought it was not the scrap value, but the precious metals that they are after? From the research I did online, Mark 2 models are a little harder to steal, and mark 3 models they actually moved the cat into the engine bay so it makes it really hard to steal. So worth maybe trading in for a mark 3?
@@redfox05nl last time I had a look, you could get aftermarket cats for the Jazz's on eBay for as little as £55. No idea of the quality or efficiency though.
I noticed theres rust on the metal lip that the boot seal mounts on. There's also some panel joins there. IMHO your boot seal isn't "nipping" onto it's metal lip and water is collecting on the lip. It's then draining into your boot through the panel joins. I'd get some rust killer on the lip, then some seam sealer. Finally I'd fit a new tailgate seal. Hopefully that will cure your leak. I'm no expert but I had a very similar leak in my car.
Yeah, so far it all seems watertight. I'll wait until the weather improves then have another look at the rust killer idea. I just find it astonishing that such an amount of waters gets in through that small tear in the boot seal!
@@gtd65 When the boot is closed, a lot of water runs off the roof and round the tailgate aperture. The only thing that stops it getting in your car is the rubber seal, so yes it;s a real pain when it goes!
@@schneil but the thing is, with the seal removed, the water wasn't getting in.
@@gtd65 Yeah that's crazy, you'd expect the car to fill right up.
@@schneil my thoughts too 😂
At 2:17 it looks there is a massive crack in the foreground, just in frame, that tou havent sealed yet...
Ben I did an update here and so far it seems to be water tight.

Thank you for this video, I was eyeballing a jazz 1.4 i-DSI, but when I started reading on the water problems, and it kind of put me off. I'm glad I saw your comment about the nip in the seal that was the problem, so I'm back on track documenting about this car. By the way what would you recommend the better engine would be, the 1.4 i-DSI or the 1.4 i-VTEC, for a city car, no highway driving?
miagy420 the water leak is usually very easy to fix with a bit of sealant at the rear rain channel, so I wouldn't let this put you off too much. I've only had experience of 2 x 1.4L DSI (UKDM) and the USDM 1.5L but not the VTEC engine. I'd guess either would be fine for city driving at the end of the day but the VTEC might have more power and or efficiency?
Just bought a 2004 jazz 1.4l dsi. As these models are fairly old now rust is to be expected. Just look around for any major signs of water ingress or cracks in the bodywork, but other than that the engine works like a dream.
@@testuser4810 they are certainly reliable little cars in general.
@@gtd65 I park my car on the street. I had for 5 years a Seat Leon mk1 without a single leak. Now I was looking for a Jazz but these kind of leak really put me off. What should I do? Do I need to buy another Seat Leon? I would hate to have to investigate water leaks all the time. I sold my Leon because I wanted a fuel economic car like the Jazz. Diesel Leon would be an option but Diesels are another nightmare more expensive than water leaks.
@@AC-db4ek it's fairly easy to see if a jazz has a leak problem. Just open the back hatch and look at the space where the spare wheel is stored. Look for any water staining or rust. Also have a look at the seams at the top of the hatch to see if there's been any work done to reseal the car.
I wouldn't be put off buying a diesel, I've been very happy with both of my Hyundai i20 and Kia Ceed diesels.
Both gave fantastic mpg and £30 per year road tax. I'm almost on 189000 miles with my Ceed.
I've just had the same problem with my 06 plate Jazz, thanks for uploading this, I'll have an investigate when it finally stops raining here in South Wales (lol). I've also had a leak into my driverside seatbelt housing, anybody else found that?
The inside of this car has been bone dry since posting this video but there was a couple of nights of very high winds and lots of rain this week. There was some water ingress into the boot but not like it was previously.
In your case, I'd double check the rain channel right along the length of the roof to see if there's any cracking at all. You'll need to move the plastic trims first of course.
Other than that, I'd have a really good look at the door seals to see if there's any damage.
@@gtd65 thanks! I've spotted some cracks up on it so going to give them a clean and a go over with sealant tomorrow. The seal in the boot was mullered, so I've patched it with duct tape while I find a new one! I really appreciate you uploading this, thank you!
@@groglorb8980 it's good that you've found some likely suspects.
I've yet to replace the back door seal but still find it ridiculous how much water could get through.
Let us all know if your repairs fix the problem.
@@gtd65 dry as a bone in there now! Your video really helped! I ended up duct taping the holes in my seal and it seemed to work! Much appreciated dude!
@@groglorb8980 that's good news, great when something works out well!
I had exactly the same problem, my hole was under the roof gutters and down the top of the boot where you sealed
The first Jazz we had leaked at the gutters as well and was an easy fix. Expected this to be the same problem.
Same problem on my 2006 civic,sealed same places as you but still leaking.
It was a quick and easy fix on the previous jazz, at the roof seams. Never had a drop of water get in again. This one is much improved but there's still something getting in somewhere..... It's a strange one that when you remove the door seal, no water gets in. That doesn't really make sense.
hello out there...I have the real same problem. and did all my investigation...last thing i will do is change the trunk sealer. ..wow what A PROBLEM THIS IS !!
What I found strange was that there was no water coming in with the door seal removed! It's normally the roof joint that causes the problem.
I've still not changed the seal.
@@gtd65 why isn't covered by Honda, this is really a manufacturing problem isn't it?
@@saltandlight4869 you'd expect it would be considered as an inherent defect.
@@saltandlight4869 This is a major problem for both the Jazz and Fit (US version) which Honda claims isn't a problem. There are loads of UTube videos for the Fit with the same problem, they all concentrate on the same issues as this vid, the roof seal and boot.
Great video. Lots of work there. I never found my leak. Have you resolved it? Thank you very much
Freddie, it seems to be ok, so far.
The usual problem is at the top of the hatch with the rain channel sealant.
@@gtd65 thank you. But I noticed that the worse part is always the wheel jack so I supose its where the water enters from... Mine is totally destroyed with rust. So you think it comes from the hatch rubber trail until the jack area? Thank you. I had to buy the entire panel, a new wheel because everything disintegrated.
@@stillalive-- I think what happens is that the water pools in the wheel well and you get water all over the jack while driving around.
Also, if there's always water you'll probably also get condensation, which might form on the jack.
@@stillalive-- it's possible your leak is above where the jack is stored but it's usually coming from the top of the hatch then running down and into the wheel well.
It's a very annoying problem, for such a reliable little car .
@@gtd65 could be that... But it has all over the trunk but what's most rusty is the jack.
Halla
what is the name of the glue you used above?
Uveys, I just used super glue because I couldn't find any rubber solution (puncture repair kit glue) at the time.
what is the name of that sticky?
also have
water in the car. nothing found. then drilled ten 8mm holes in the bottom so that the water can drain :-). .... after the video I will buy a seal
Heiko, did you check the roof gutters for possible cracking?
@@gtd65 Thanks for the tip, I'll check that tomorrow
@@haigocraft that's the most common problem with the Honda Jazz for water ingress. It's a fairly easy fix.
What kind of mechanic works on this problem?
Cynthia, I would think any local mechanic could do this for you. Just tell them you have a water leak.
ua-cam.com/video/WSEU8StkG_c/v-deo.html maybe this is going on as well - water coming in through the rear door(s)
What’s the name of the sealer?
You can use a polyurethane seam sealer. There's brands like Sikaflex but any would likely do. I used Hammerite paint, which worked perfectly.
