Starting in the model year 2015, Mazda Canada is extending its new vehicle warranty program to include unlimited mileage, while retaining the time limits on its coverage.

While the changes to the 3 year bumper to bumper and 5 year powertrain warranty will be welcome news, the important one for Canadians is the 7 year anti-perforation coverage, which no longer has a mileage limit. Scarred by the legacy of the first-generation Mazda3 and its notorious corrosion problems, the new coverage should bolster the brand in the eyes of Canadians, who are in a constant battle against rust, thanks to winter weather and liberal use of road salt.

    This is welcome news. While looking for my current vehicle a couple of years ago, I was seriously considering a Mazda 3 GT. However, having owned a 2002 Mazda MPV for 3 years made me decide to go with something else.

    Mechanically, that MPV was a great vehicle. Every issue I had with it was rust-related. The body rusted out, the exhaust rusted and detached, and the list goes on. The underside of the hood was so bad that every time I closed it, a rust cloud would fall to the ground. Even the license plate bolts in the rear rusted off and took part of the body panel with them. I had my plate held on with zip ties by the time I sold it at auction. Don’t get me started on the fenders or quarter panels either.

    I know someone with a first generation Mazda 3 and it seems that it is a lot more rust resistant than my MPV ever was. This perforation warranty should change quite a few people’s minds.

    Obvious solution is obvious: corrosion is a function of time, not distance.

    Wut, no mag-chlor?

      Distance, over Canada roads especially, increases exposure to catalysts that promote corrosion. It makes a difference when the car is constantly getting bombarded with salt brine, being sandblasted by aggregates and emersed in a slushy slurry.

    enough with the hyperbole, out with the fine print. (yearly coatings, biyearly inspections)

      If its anything like their previous corrosion coverage they tried to sell me when I was looking at a mazda, it would have required inspections by them every two years and even then they try to find a rock chip or anything else they can blame.

    That’s the problem I’ve always had with warranties. Certain items have no business being mileage related.

    The first thing a service department does, on any car for any reason, is check the odometer. Does it matter how many miles I drive if the radio goes dead or a window down switch stops working?

    It would be good to have components put under a time warranty or a mileage warranty, depending on the system. Unlimited mileage on everything doesn’t hurt either though.

      “Does it matter how many miles I drive if the radio goes dead or a window down switch stops working?”

      Miles might not be the best exact approximation of usage (ignition on or engine hours might be better), however the condition of your switch diminishes primarily with use, which generally occurs when you are in your car accruing mileage, ditto for the radio. Sitting in the garage unoccupied over long periods of time isn’t when it gets used.

        I agree with you to a point, but the life of certain solid state electronics or infrequently used mechanical switches will be affected by much different factors than drivetrain or suspension components.

        For instance, a lot of people on TTAC confess to never using the sunroof. A lot of people also rarely have back seat passengers or open the rear windows. Those switches and actuators will see mere minutes, if not seconds, of use over 3 years time. 24 months into ownership (which would be when I’ve passed 36k miles, based on my driving), if such a person found out the switch wasn’t working, he’d be on the hook for several hundred dollars’ worth of repairs for fixing something that might have gotten used once or twice.

    Arguably, the downside of a long warranty is it gives the dealer many more opportunities to bend you over. Your mileage may vary.

    Good news for Mazda buyers.They must have confidence in their products.Ford is really having an expensive hard time with their warranty costs, which leaves their customers with little confidence.

    I have no intention of buying a Mazda, or any other car for that matter. When I see a Mazda I think “wow, nice looking car, too bad they rust” I’m a Canadian, and I’m very much aware that our climate, kills all cars. Its not just perception, the Mazda’s are the worst rusters. So maybe this new warranty will sway a few buyers. I want to see a five year old Mazda with no rust issues.

    @ Derek I was going to recommend, you treat your new car to a Krown spray. Think about if you planning on buying it after lease. I’ve just lost so many nice cars to the rust monster. Its heart breaking.

      +1. Even on a lease, I’d take it to Krown.

      North American-built Mazdas have generally been rust-resistant; I don’t think I’ve ever seen a rusted-out 6. The 3 might fall under this umbrella now.

        I’m not buying it out after, so I don’t think I will.

        • 0 avatar

          I claimed and received with no fanfare whatsoever, bodywork and paint around every badly-drilled hole Krown made in my ’99 Impreza. After four years with treatments every year from new, rust was obvious to my then 84 year old mother who thought it looked bad. Krown paid right up., after a two minute “inspection”.

          Perhaos the Krown “technicians” need to buy new drills every now and then, or drill pilot holes first. Shoddy work doesn’t begin to cover the mess they made.

          Don’t bother with this trearment, they just make things worse.

        Depends on where your dealers are located. I just took one of mine on a 260mi round trip for a spray and have another appt in December for the other one.

    “…liberal use of road salt.”

    I’m waiting for someone in the audience to blame Saul Alinsky for the snow.

  • avatar

    I’m taking my Impala in next week . The Krown guy I go to is an owner operator . Small town guy that’s been at the same location for years. I’m not crazy about the whole drilling thing. However there is parts of the body you simply can’t excess any other way.

      Where is it? I have friends who need to go there.

      Drilling sounds horribly unnecessary to me. If you can’t get oil into somewhere without drilling a hole, then how can water and salt possibly get into there?

      This is coming from the Canadian original owner of a Mazda3 that will be 11 years old next spring, with no sign of body rust. I brush out the rear fender lip and spray it with green-bottle Rust Check every seasonal tire change, spraying some of the thinner red stuff in the drain holes of the doors at the same time. If the rear fender was like the front and had a plastic liner to keep the dirt and salt from collecting, I’m not sure I’d even need to do that.

      Western Canada is nothing like Eastern Canada when it comes to rusting though. Nowhere near the amount of salt and humidity here. Used cars imported from Eastern Canada are easy to spot. Just look at anything aluminum under the hood, including the radiator. Nothing aluminum has a clean surface finish after a winter out there.

        @rpn453…..Right you are. Your Mazda has held up well, only because of where you live. Drilling holes sucks. I’ve tried everything, every product, every method. Krown sprayed into every nook and cranny is the best, Not just the body panels, its the brake and fuel lines. Call your Mazda dealer, or good independent, get a price on parts and labour to do brake and fuel lines.

        If it has worked for you, the only logical thing is to keep doing it! I do see a lot of Mazda3s of my generation with rear fender rust. I’ve even seen a couple that were at least two years newer and rusted right through. I’ve always assumed the worst ones came from Ontario though. Dealers import a lot of Eastern cars because used cars are more valuable here. You find that out in a hurry if you check out the inventory at used car lots. You don’t expect to see much rust on a purely Western Canadian car until it’s at least twenty years old.

        A few years ago I did rear brake lines, from master cylinder to caliper, on a ’93 MX-6 that spent its first eight years in Ontario. It wasn’t very expensive, but it was an extremely unpleasant job. I had planned on doing only the rusted section in the middle but I gave up on the worthless misaligned Chinese flaring tools and just bought straight sections of pre-flared brake line instead. I guess it wouldn’t have been too bad if I had known to just do that going in.

    I find it odd that some years after Mazda reduced their US warranty from 4/48 to 3/36, they’re increasing it in Canada.

    (Apologies for duplicating myself from the other thread, but this is really the more appropriate place for it.)

    When my 2006 Mazda5 GT started rusting (after 2.5 years of ownership and 46,000km), it was still under warranty, and had been undercoated and rustproofed when new from the Mazda dealer, with annual inspections and resprays. Two separate dealers did everything they could to deny my warranty claim (Agincourt Mazda and Scarboro Mazda for those of you in the GTA), and only escalated to the regional rep after I caused a scene in the service department. They actually had the nerve to tell me that it was my fault for driving in the city!

    All Mazda did was respray the rusted surface. I could still see the bubbling underneath the “fix”. Needless to say the car continued to rust and I sold it after 4 years at a considerable loss. Rust is terrible for resale.

    I don’t care if Mazda extends a warranty if they’re not speaking about what they have actually done in their manufdacturing process to prevent rust. I will never purchase a Mazda again.

    Perforation warranty is useless since no one drives 4 yeats with a rust-brown call till it perforates.

    And they void the warranty when the wheelwell get hit by stones. Which they do sine they are around the wheel. I tried to get rust fixed for my Mazda 3…… after dealer refused to fix I annually derusted it, painted, used Sikaflez for the inner parts..

    If you ever buy a Mazda – you have been warned.

    The Mazda 6 holds up well in year 7 now. But I won’t a car when quality is a hit-and-miss. I prefer 1 year warranty that I nver need over 10 year warranty I have to use daily and fight over.

      This is exactly the issue, every rust perforation warranty is useless.

      Even the worst rust bucket won’t rust through a panel (to form a hole) in the time period of the warranty. Could have tons of surface rust or bubbles, but that isn’t covered by the warranty.

        The 6 year perforation corrosion warranty is the minimum required by Transport Canada. Most makes offer more. This rule was introduced after the horrible experiences of the cars from the 70’s, where steel of mostly remelted scrap and unlined box fenders resulted in perforation after as little as 18 months and structural safety of the unibody was compromised. Plastic fender liners were a big plus. Properly zinc coated steel works very well, if the automaker wants to spring for it. Galvanizing works even better, but that is more $ yet. The technology is available for the body to go 15-20 years under Canadian conditions without supplemental oil spray, but only if the carmaker uses it (very very few do).

    Besides alleviating rust concerns, combining efficient engines with warranties based only on time should make Mazdas attractive to anyone piling on miles at an above average pace.

    Hmm recall the tugboat days when rust was a non issue? Had 99 Protege no zoom zoom rust there. What’s going on Mazda?

    Perforation warranty can only be claimed if the rust develops a puncture on the steel, and it is voided once aftermarket rust protection is applied. At least that’s how I understand it. Friends have told me the dealership will fight tooth and nail to try and deny a claim.

    I’ve also heard from others that Krown would drill into doors where a simple pull of the inner door trim would have allow them access into the inside of the doors, or drill into the underside of the body when there are rubber gaskets that could be pulled to access the same places otherwise (e.g. FRS/BRZ).

    Mazda looking desperate for sales. Maybe others will follow if it helps with those sales.
