Water in the boot / wet carpets (Honda Jazz 2002-2008)

[E27006]

 I believed the leaks affected the Jazz cars assembled in China, Japanese assembled cars were not affected and the changeover for source of manufacture  was around 2008,  The failure is believed to be of a mastic panel-to-panel sealing compound which cracks and brittles in UK winter  temperatures allowing water  to seep between the body panels of the rear of the car

My Jazz was made in Japan and has the wet boot problem.

Flaky paint seems to be a Mk 2 issue.

We have a 2005 SE version that had water in the boot when we bought it we innocently thought that the boot had been open for some reason at the time as it was raining heavy for a while , yes we can be gullible . But as we had had it a few days we still had this problem even after i had mopped it all up previous , it was getting worrying, i had the boot seal off, the back lights off , and the roof trim removed and cleaned the guttering there but couldn't trace it, it looked all fine then a few day's back on a dry day i got the hosepipe out and worked a slow stream of water from the lights up nothing ! Arggh, then i focused near the rear of the roof trim in the gutter where the rubberised strip lies right at the rear near the boot hinge the water appeared " got you " i thought YES there was a hairline crack in the mastic seal next to the rubber boot supplying the electrics to the boot hatch and same on the opposite side .
I applied some caravan mastic and it solved the water ingress so from my experience check this area first as it was not obvious and hard to get to.

Yes, that's the standard place for a leak on a Mk1 Jazz.

For me any mk1 version could be subject to the problem regardless of the year of manufacture. In 2005, 2006, 2007 or 2008 the assembly pieces remained the same.

It depends on how well the mastic was applied, not on the parts used. It appears to be a Quality Control issue.

Also had this issue on a recently purchased 06 jazz. I added the sealent, and no more water. I remain very sceptical though, as the amount of water that was in the spare wheel well was a lot. I could literally hear it splashing around when I was driving.

I also ended up having wet carpets on rear passenger foot floor, which I would like to assume was due to the massive amount of water in the spare wheel well?

2003 model here
Leaky aswell...

But some previous owner did something else to tackle this issue.
He just drilled a small hole on the lowest point of the trunk.
Whatever leaks in, will also leak out

In the long run it’s easier to to resolve the issue by scraping out the cracks and resealing and using lock tight around threads where damper units are mounted because where the water runs down it will cause corrosion.

Indeed, i have some sealant ready in garage but i gotta wait till its not -10°C outside
