Hi Lennie
My car does not have any rust issues. Hope I have answered your question?

My jazz has also rust spots, cannot believe it!

I’m another shocked Jazz owner (2014 model) who’s car rust is being fixed as I type.

That's annoying. I would definately push it as a safety issue if it is distracting you from your driving then it needs to be replaced. Mine certainly doesn't do it. We don't or have never owned a car that has. If the dealer won't I would take it to another. Good luck!

Mine is 2009 model

Hi Bob, I purchased my Honda Jazz in January 2015 (Dec. 2014 model) and in 2016 I noticed the first rust spots under the bonnet. I reported it to the service staff at Hoskins Honda (now Sutton City). They took some photos and promised to contact me. Nothing happened so at the next service I reported it again. By now rust spread to engine bay and the hatch door.
They took more photos and promised to contact me again. Since nothing happened I contacted Honda Australia. They advised me to deal with Sutton city. They took more photos (two years later) and I haven't heard from them since.
When I requested all further communication to be conducted in writing they went dead quiet and even rejected my registered letter which I than posted to Melbourne Honda Australia. No answer, so today I am attending the first session at NCAT.

I have a Jazz first registered December, 2016 and noticed rust under the bonnet and hatch. Nordic have arranged for the car to go to a crash repairer to have it rectified. My worry is that I can only see rust in very obvious places and there may be more I can't see. The front driver side door was also leaking badly. NOT HAPPY.
