05 Mazda 3 Corrosion Success Story!!
I have an 05 Mazda GS, bought in London, ON.
I discovered rust on rear wheel wells earlier this year, and have watched it develop.
At the same time, I was reading the threads here regarding the same issue on other M3's in Canada.
Here's my story...
The rust started developing on LH rear wheel well in the winter of 08 (@ approx 75k km). Didn't think much until reading this forum, and seeing others with same issue.
Rust continued to develop this spring/summer. Now extensive rust on LH well as well as rear RH well (underside).
I then went to my Mazda dealer in London, armed & prepared for a fight over the definition of "perforation" rust, and ready to detail other owners' success in covering this issue. When I called them, they were not surprised to hear of 'rust' issues. I brought it in, and within 5 minutes of arrival, the service manager greeted me, and started taking pictures of my car.
She new exactly where to look, and in fact showed me other areas of my car that had become corroded. In addition to my wheel wells, 3 of the 4 pax doors showed a subtle 'bubbling' in between seams.
She told me that 1) 90% sure all corrosion would be covered; and 2) all Mazda 3's have been re-warranteed with 6 year perforation rust warranty. She would call Mazda Canada with photos to confim coverage.
She said that this issue started rearing its head in 07, about 3 years after the 04 model. At first, all claims were rejected. After so many claims came in, Mazda Canada realized this was a manufacturing issue, and therefore increased peforation rust warranty to 6 years, and began accepting the claims. They did so even with small rust issues, since they knew these cars would be coming back in a year or two with more rust.
So......the answer came back to me.....all corrosions issues will be covered by Mazda @ 100%
She also asked that I come on this forum to inform all M3 owners that Mazda Canada is AWARE of this issue, and will now cover repairs under warranty, provided they meet the new corrosion definitions. Mazda 3 models from 2004-2006 will likely be affected now, but WATCH YOUR CAR. She also said the 2010 Mazda 3 has fixed this manufacturing issue......it took that long to develop & correct.
Anyhoo.......I have pictures and will post them soon. Until then, I still love my Mazda 3, and am quite pleased with Probart Mazda in London.........and encourage all M3 owners to take a good look at theirs, and send 'em in if there is any rust.
I hope that helps,
