Class action settlement for defective exhaust valve seals/oil burning 2021 CX-5 CX-9 2.5T etc

Posting another update. The smoking never went away and the car made it a whopping 1,112 miles before the low oil pressure light came on since they did the valve seal replacement and oil change.

Dropped it back off today. Service guy said they had another CX5 with "very similar" issues that had to get the valve seals replaced again, because they were leaking.

Seems to be the dealership not wanting to fix their mistakes on their own dime and try to get some reimbursement from Mazda
Unfortunately the dealer did a botch job/ butcher job on your valve seal replacement meaning they didn't know what they were doing and most likely now ruined and possibly damaged way more more than you came in for. Of course they will admit no wrongdoing and want to bang Mazda for any more time on repairs when the real problem is that the tech who did it absolutely sucks and is the reason another person had the same issue. I wish you luck and please update us again because in no way should your engine consume that much oil that your light comes on in 1k miles. Thats nuts. They screwed it up bad.

Make sure you request a Master tech look at it. These are the reasons why I don't like my car being disassembled for complex warranty work.

Did you watch the video of the valve seal replacement - post#100 ?

I did watch it. Seems very complicated, but it's the technician's job. The service guy was mentioned that there were like 5 other 2.5T vehicles that needed the repair when I dropped my vehicle off, but Mazda only sent one valve replacement tool to each dealership and may take a while for the repairs to be done.

It's now been more than 6 weeks since I had the valve seals replaced on my vehicle initially, so hopefully they got to practice on a few more valve seal replacements and have more experience.

I hope this time you have a positive result. I've gone 5,000 miles in my 21 CX-5 Sig since the seals were replaced and the dipstick is still at the full mark; it has never smoked. 39,700 total miles. Had the oil changed along with ATF, differential fluids, brake fluid, spark plugs, and BG intake cleaning. The plugs looked great, not sure why the turbo has such a short change schedule. Brake pads are fine, probably because 80-90% of my miles are freeway/highway miles. I enjoy this car enough to likely keep it another 3-5 years. Fingers crossed.
 
The plugs looked great, not sure why the turbo has such a short change schedule.
It's due to the laser iridium part being specced from NGK at 40K miles while the other plugs are 80K miles. So, it seems Mazda is simply following NGK spec.
 
I am hopeful I will either move on to another car before I get to 84mths/84k miles, or don't have the issue crop up in that time. I have yet to get a low oil warning in my 28k miles. 5k interval oil changes are done at the dealership.

10 days later, I picked up my car today and they re-did the valve seal TSB. Of course, I drive out of the lot and notice that my car is driving poorly, tachometer needle was bouncing around, had issues accelerating and a lot of vibration when accelerating. Went right back and it was a fouled spark plug, it got oil on it. Waited around for another 45 minutes to get that done.

So, hopefully everything is alright now and hopefully not need to post an update about my car regarding this valve seal again.

Huh, I guess dealerships don't "test drive" a vehicle after they do work to verify everything is okay anymore?? Jeez 🙄
 
I have a 2021 CX-9. I had a year and a half of free oil changes and brought it in telling them that it was burning oil. I was told that was normal for a new car especially one with a turbo charged engine. Like many others I keep oil in my car now because it is definitely burning it.
After receiving the postcard I called my dealership to schedule the repairs. Twice I was told I would receive a call back and didn’t. Finally when I spoke to the service manager I was told I would have to come in for an oil change. Then after driving 600-1000 miles I would bring the car back in for an oil consumption test. I told them that that is not what is stated in the post card I received. Does anyone know if that is true? Do I have to have that test done or is me saying it is burning oil enough?
Primarily, an oil consumption test is merely to validate that the problem really exists, not some dummy forgetting to put that last quart of oil in your engine or, heaven forbid, an oil leak somewhere not too noticeable. In regards to dumping the vehicle through selling, make sure to tell the purchaser that this issue exists otherwise that might come back to bite you unless it's a dealer of course. And, if you think this oil burning state is bad, wait until you see what it does to your piston rings and catalytic converter. Valve seals may prove to be the least of your problems.
 
I had my low oil level warning come up, I was supposed to take it in the day after but something else came up and had to add oil so I could go on my weekend trip that was planned way in advance.
Would that code still show up if they pull up the codes? What else can I do to prove that the code was there? I don’t think I took a picture of it as I usually would but didn’t get a chance.
It’s a 2021 CX9 with about 60k miles.

Yes, the code should have been stored. You don't need to prove anything though, the light coming on is not required any longer. You have to simply state you have needed to add oil between changes and the light has come. You also have an extended engine warranty and related components ONLY for damage to them directly due to the defective exhaust valve stem seals. Not something like a water pump etc. That extension is for up to 7 years and 84k miles. Take it in and have it fixed free.

Apparently this isn't the case for some when they have tried to have the issue fixed. Some dealers don't seem to be "getting the memo"...
 
It should be that easy, but several have posted that the dealers are still wanting to do oil consumption testing. Maybe if they are pushed to call Mazda tech service they will understand this isn't needed.

btw are there any stipulations if car mileage is past warranty or not? When the code came up I was just under 60k miles now I'm at 60,300 miles. My oil change appointment is tomorrow. I'll state when the low oil warning came up, the mileage from the last oil change and now to show its under 7500miles and that I had to add a quart. Will the scanner show the exact mileage when the code came up? I don't want them to claim that it's out of warranty now and they can't perform any work.

No stipulations because your VIN falls under the class action service campaign which extends the warranty to 7 years 84k miles automatically for this issue. Additionally, when a code is set, the ECM/PCM logs freeze frame data of when the code was triggered, mileage and under what conditions. Now, there are reports that the low oil light has come on for some oeople and dealers are saying no code has been logged. I personally don't believe that and think dealers just blow it off and don't even bother properly scanning or scan at all, but in any case it is NOT required any longer for the repair to be performed. It is black and white and you also do NOT need to have an oil consumption test done either by the dealer to have the repair done. It is all clearly laid out to them from multiple communications from Mazda headquarters. So, do not let them tell you they have to do this or that first. Some dealers already know the deal and take care of it without hesitation and some will fight you tooth and nail because they are ignorant, uninformed or lazy. Just stand your ground firmly if you get any nonsense or pushback and tell them you know the case and the requirements and to fix it or you will open a case with Mazda. I despise dealerships who think they can do or say whatever they want and treat you like you are stupid. Just be firm and polite and speak to the service director if need be. Sometimes service advisors "salesman" are dumb as a box of rocks.

Hope that helps.
