I understand that the Mazda 6 (2002 - 2007) had rust issues. This is also mentioned in HJ's CBCB.
I gather that this is partly caused by poor welding on the wheel arches, the inner arch not being closed of properly, etc.
Apparently even the Mazda 3 suffers from this, and particulalry viciously in the US and Canada. Wonder whether Mazda as a company has poor manufacturing practices, in this regard?
I also notice that Mazda had a 6 year corrosion guarantee on the Mazda 6 till 2005, then increased it to 12 years from 2006.
Any idea whether MAZDA has made any modifications to the car to address corrosion? Or was this just a marketing ploy to increase customer confidence?
Also any idea if the car body is galvanised? If so has it always been galvanised, even pre-2006?
Any one has experienced rust on a 2006 and onwards model of Mazda6?
