I have 92,000 miles on my Mazda CX-5 with the faulty valve seals. When I first purchased the vehicle it would burn oil on occasion. Not all the time. Now it seams to have stopped burning oil. What would cause this? Is there buildup on the valve stems which causes a better seal? Is the oil pressure lower? Do the seals swell over time? I am trying to decide if I want to push the dealer to have the seals replaced. 90% of miles are highway.

Yeah that could be just natural sealing somehow, of course I really have no idea.
Have you tried a "high mileage' oil, I believe they add seal conditioners and that might help.
Is is under warranty?

I sent an email to Mazda Canada that day to ask the same question. I'll post here with their reply when I get it.

So here's what the rep said. This happened to be the same guy I was dealing with for my rear diff issue.
He wrote:
This is, quite honestly, a very low-effort response since the CSP11 documentation provides the information he just mentioned. Not to mention the fact that the CX-9 has never been made in the USA. I replied immediately asking why Canadian CX-9s would not be included despite our VINs falling within the affected range, and with the only differences between US and Canadian vehicles being the trim level names and the countries they happen to be sold in. We'll see what they say, but it seems like Mazda Canada is not acknowledging CSP11 at the moment.

Class action I guess. I like Mazda, but there's no defending to this type of idiotic decisions.
I still don’t fully trust mazda Canada’s response. I find the customer services of most brands know very little more than other things. The only way to really know is to get a good service manager from Canada to tell us, or to have someone having lived through it.
One thing is for sure though, I have not received a mail notice in Canada from Mazda notifying me of the extended warranty.

Which answers your question. Those were mailed out to US owners months ago.

Yes, what it comes down to is that the class action and settlement were drawn up specifically for US citizens. As a result, Mazda USA's only legal obligation (regarding the settlement) is to US owners.
With that said, this does provide a precedent for Canadian owners. While there are currently no legal proceedings to force Mazda Canada to issue a special service program/extended warranty, this settlement identifies the issue and Mazda USA has a plan of action established to address it. It may be as simple as someone in Canada starting a class-action and using the US class-action as a precedent.
It's only right that Mazda Canada take care of those affected. It would be a great idea for them to take the initiative and offer the same extended warranty to Canadian owners.

My thinking is the settlement in the US won't help us. Not sure it ever got to trial, Mazda likely settled early so that they could limit their damages. In Canada we'd need to go through the same process, however courts here tend to be limited in terms of punitive damages.
I guess we'd have to start with finding Canadians with this issue. Hopefully I'm not the first.

I would say it depends on your local laws. In Quebec there are strong consumer protections laws, and I think you could make a case for it. The US extension of warranty is pretty much an admission by Mazda that there is an underlying issue. However those laws would only help single individuals to get their claim covered, not really force Mazda to extend a warranty problem.
Also, with the powertrain warranty in Canada be for 5 years/ unlimited kilometres, it is likely that most early case of cracked cylinder heads have already been covered under the original warranty. I still wish we had the US 10 years extended warranty though.

Circling back. Heading in for an oil change Friday. ~5600 miles since last change and 52k on the car. I took a picture of oil level immediately after the oil change and it was on the bottom of the top dipstick hole. Earlier this week I checked and it was about the top of the bottom hole. So it's lost somewhere from 0.75-1 quart over 5600 miles. This seems significant to me. Is it significant enough to push to get the fix done since there seems to be instances of the seal replacement causing other issues?
Yours is a turbo, correct? If so, I would say yes, you should asking for the TSB to be done. Mine never drops between oil changes.
Yes. Turbo. I noticed oil level dropping between changes from the start. I seem to be on the lower side of bad compared to others.
