Looks like the problem is still with the alloys  >:(
Can any Mazda Techs shine a light on this.

It's not "techie" issue, just a well known and highly documented situation that has been going on since 2004.  Mazda  (or in actual fact the sub contractor who makes the wheels) have never manufactured or coated their wheels to contend with the climate in this country. Over the years I have spoken with many people in multiple countries who have never had a problem with this kind of corrosion. It's a combination of UK weather conditions and the chemicals that are invariably used on our roads during the winter months.

I have in the past spoken directly to a Mazda engineer at Mazda UK who acknowledged that this was the case, but for Mazda to make an exception by manufacturing or fitting different wheels to UK spec models is out of the question. This is why Mazda have usually honoured every claim under warranty and have even gone so far in some cases to offer a goodwill donation to help towards replacing affected wheels outside of the warranty period.
I myself have had 4 complete sets of wheels. Three inside warranty and one set just outside, so I have plenty of experience of this.
Of course as a company Mazda are never going to continually replace wheels past the warranty end and I think I'm right in saying that even if you take out an extended warranty, the wheels are not covered.

Unfortunately this is the Achilles heel of most Mazda 3's and to some degree other Mazda's also.  Although this will not make you feel any better, we are not alone.  BMW, and Toyota have also experienced the same problem.
There are many topics covering this on the Forum including some that go some way to explaning the chemical interactions that cause the corrosion. There are also some offering advice regarding protecting the wheels (coatings & polish etc).  There are also some relating to refurbishing and powder coating them to resolve the issue. Of course the last ditch solution is to change the wheels for an aftermarket style that can combat the elements better than the OEM's.

Hope this helps.

Thanks for the reply, yes that does explain why the problem is still about.

Thanks Tony

Hmm.  Not a chance. was the reply.  Full dealer service history, and I 'm the original owner.  I payed full whack as it was one of the very first BM models in the UK (7th I was told)

Still in Warranty (up to the 27th of Jan and this was the reply before the warranty run out).  That's because despite  keeping the car detailed and absolutely immaculate the wheels are only just going on the outward facing side, they're all bad where its on view on the inner sides... but most people have a layer of dirt. So that doesn't count.

 I suspect if I had abused the car by not looking after it, they would have been replaced.  Because I super detail its not the case....that to me sucks! You would think they would be interested in keeping an enthusiasts car looking superly nice, but instead it just highlights things.

This car BTW is one of three Mazda's in our household and the second one I have purchased brand new from Mazda. 

I just know if nothing is done I won't buying another. (It just doesn't make any business sense either!)

At 5 years mine are bubbly in places, however a little perspective is a nice thing. They have less corrosion than the 2nd replacement set on the wife's ds3 which is 2.5 years old and has done 11k not 56.

I plan to get them refurbished when they get bad but they are still OK from 3 yards at the moment.

I had my Mazda 3 2010 wheels shot blasted and powder coated for £40 a corner and so far they are as good as new. The problem isn't solely with Mazda, most Japanese manufacturers have the same issue
