Honda Jazz / Fit water in the boot / trunk fix.

Honda Jazz water in boot and/or rear footwell fix.
In this video I detail how to stop your Honda Jazz boot from filling with water. This can also cause condensation and even ice on the inside of the cars windows. I hope this helps.
Hello everyone interested enough in this channel to visit here.
I'm just a single Dad whose son wanted his own TH-cam channel to try and make some money because, quite frankly, we're pretty poor. Sadface.
But we're really happy together and I'd do anything for him, including making all sorts of random videos to upload to TH-cam.
As such there's going to be games, reviews of various things and, as I generally can't afford to pay to get things fixed, anything I'm repairing that I can video I'll also upload.
Whatever you're doing folks I hope you're more successful at it that I am, take care and stay safe.
PLEASE SUBSCRIBE.
Peace.

That looks oh-so familiar! As well as the cracks by the hatch hinges, I found some water was getting in behind the brake lights.

@thromboid 🫤 I honestly wouldn't believe Honda could've made such an error if I'd not seen it first hand. When bathroom sealant from poundland fixes your car, you know something's not been made right. I understand the gen 2 cars don't have the issue so they did at least learn from their mistake.

@@channelone4655 My first repair used Flex Glue which also became brittle after a couple of years. Last time I upgraded to a Sikaflex automotive adhesive/sealant which I have greater hopes for...

A panelbeating shop mentioned that it can be helped with some additional spot welds in the roof, but I doubt it would be worth the hassle. I've heard headliner removal is a bit of a herculean task!

Rear foot wells could be the plastic aprons behind the door cards and the door seals at the bottom where they flatten out. I tried clear silicone but had to do it all again with seam sealant and RTV on the aprons. Pricier but lessons learned.

[@channelone4655]

I have actually seen that when I was looking for possible causes so you're absolutely right that the rear door/window sealing can cause this too. Thankfully I the months since sealing the roof we've had no problems.

i think all the 1st Gen Fit / Jazz is experiencing the same leaking issues. I also drive the same car model. I have used silicone to cover whatever gaps on the boot to stop the water from going in. Even went back to the dealer to get his mechanics to get it fixed. It has improved now but is still leaking, I thought he sold me a broken car till I saw many videos here reporting about this issue for the same model,

[@channelone4655]

Yep sadly it's very common on these and not what you expect from Honda. The design is no different to most cars they just chose a poor sealant. The bean counters at work trying to save a few pennies no doubt.

Had this problem in me old mk4 astra once,turned out it was the wiring loom going into the car to the boot,the rubber was fucked and was letting in water

[@channelone4655]

Oh gosh. Whenever I've mentioned this to someone they've all had leaks from different places on different cars. It wouldn't be so bad but usually by the time you notice, carpets etc are soaked.

0:50 & 3:43 These splits should never have occurred. I was an inspector in the aircraft industry. Any aircraft with this type of split would have been grounded. This split is flexing, widening and lengthening. One TH-cam shows the channel split running over halfway the length of the roof line. A structural failure. A water sealant will not stop its progress. Like the Titanic's pumps it will only buy you time.The flexing at the drop off is widening the split along the roof and downward toward the spare tire well. As there are so many video on this subject - it is a systemic problem. Something very bad about how these vehicles were made is evident. Such a shame. I have always though the first generation Fit was the most aesthetic and wicked to drive.
My guess is rough driving might begin the flexing. Or perhaps water entering a split then freeze - thaw repeated over years would widen it. The same as happens in nature to a boulder.

[@channelone4655]

I looked into myself before attacking the problem and I didn't see any examples of the welds spliting. It just seems the bean counters got involved at some point and decided a cheaper sealant would work. Which it clearly hasn't. There's no lay-bys in the sky which is why their quality control is higher (disregarding Boeing anyway). We've had managers from the automotive industry join where I work who all shared the car makers mantra of, get it out the door and fix problems under warranty. It seems car buyers are doing the development work for the manufacturers.

@josephbingham1255 Since the video the car has been written off but thanks for the info. It's all quite interesting for such a major manufacturer to make such a blunder.

@@channelone4655 I bought my wife and I two new Honda Civic Si hatchbacks in 1992. Both upon revving gave a "bearing" sound. I took them back to the dealer in the first month. I talked with the dealer's mechanic that worked on them. Both had "very tight valves" which he adjusted. The engines came from the Canadian factory that way. Also a friend who was the senior technical writer for Honda Motorcycles USA ( a champion dirt track rider) and I discovered something odd about the timing. We removed a spark plug and inserted a long stiff narrow plastic rod to the top of the piston. By hand cranking the engine and watching the rod reach its lifted peak you could locate top dead center. The timing marks supposedly used for valve adjustments did not line up where the instruction book said top dead center was. The V-Tech motor was said to have timing that changed during high revs so maybe it was something to do with that. He wrote a letter to Honda Automobiles USA and they did not respond.
One final thought. My experience was that Toyota executives were gentlemen interested in feedback to improve their product. And acted upon it. Hyundai executives,' We don't accept unsolicited comments." 😂
