Mazda CX-9 TSB Valve Stem Seals & Oil Consumption - Low Level Oil Light - Is the CX-9 Burning Oil?

[@cardona3623]

My 21 mazda 3 turbo at the dealership as we speak for the same reason. They said they will fix it at no charge. Had the low oil light go off for the first time with 55k miles. They are definitely aware of this problem and did not ask any questions.

[@lpeddle8404]

Just what I was looking for in my research on this vehicle. Thank you, thank you Sir. It is a gorgeous car that can obviously get ugly real fast if you don't do your homework. I just saw and test drove this same model yesterday that falls in that VIN range and it is very concerning for me. I'm going back tommorrow and checking this. I will demand an OBDC readout to see if it ever threw that error after I look at it's dipstick and service record. If either one is not what it should be I'm going to have my say but I'm not touching any CX 9 that falls within that manufacturing range. Subscribed.

[@RandomEarthMedia]

Thank you for watching and glad my video helped. I will say that I had my valve stems replaced over a year ago and I have had no issues since. Doesn't Burns oil anymore and I've had zero problems since the repair. It's been a great car and I have not had any problems whatsoever. I am now at 43,000 miles.

[@lpeddle8404]

@@RandomEarthMedia Thanks for replying REM. When you say burns oil what exactly do you mean? It still shouldn't be losing oil should it.

[@RandomEarthMedia]

Sorry that was a typo it was supposed to say does not burn oil anymore.

[@Travis8126]

My 2021 CX-9 had this same problem at 35k miles, currently at the dealer being repaired. Mazda gave us a loaner vehicle. So far they have handled it perfectly, no questions asked. Sounds like they are taking care of there customers on this. Does anyone know if this is only on 2021 models?

[@Jaybeezcuits]

A law suit just settled and Mazda must fix that issue beacuse its a manufacturers issue. I just left my Mazda 3 at the dealer to get fixed, about 3 weeks to fix it.

[@Matys1975]

My Mazda dealer overfills all CX-9s regardless of what year they are as a matter of policy. I have a 2020 CX-9 (wife’s car) that is not covered under the TSB, and it does not appear to burn oil but they overfill it anyway, although not quite as much as you are showing in the video. I would say my dealer overfills it by about half as much as what you are showing. I was told a similar story by the dealership as you. I do also have a 2021 Mazda 6 that is covered by the TSB but luckily I am not seeing it burn much oil at all. In 2k miles I barely see any change in the level on the dipstick. The Mazda 6 is my baby so I change the oil myself.

[@RandomEarthMedia]

Thanks for watching and commenting. I guess I'm not alone and other dealerships are doing the same thing.

[@johnkohlmeyer1499]

You won’t see oil consumption until around 3-3500. When the dealer monitors they are only required to test consumption and around 1200 miles which is a joke, but my car will not make the full 5000 mile interval of oil changes without needing oil

[@Kudzeee]

2021 cx5 ce turbo here... I have to add half quart every 4k miles. Didn't ask the dealership about it, but I think I will sell it soon and buy something more reliable. CE turbo is awesome, I felt that I hit the bucks for that money... until I started experiencing oil consumption 😅

[@MrCodyswanson]

Mazda just extended the factory powertrain warranty in the US on the 2.5L turbo to 84 months or 85k miles.

[@lpeddle8404]

Do you have any idea or heard if this is also the case in Canada?

[@shazam66]

Dot to dot on the dip stick is 1 liter.

[@donreinholz8121]

That engine takes 4.5 qts when you change the oil and filter. I am curious if a person used Valvoline Restore and Protect if that would clear up this issue. In order to keep warranty relevant you must have the dealer do all maintenance. Dealer changed mine and it was exactly on the full mark.

[@johnkohlmeyer1499]

I have the exact problem with my 2021 cx5. They claimed there was no tsb until I found it and showed it to them. They changed the seals and I haven’t made it to the next oil change interval and the light came on again😡 I think they deliberately over filled so you wouldn’t notice. Note I have to go back and tell them it’s still using oil. I found the problem before 36000 miles.

[@RandomEarthMedia]

I just had my seals replaced last week. That's good to know it may not have fixed the issue. I'll be keeping a close eye on the oil level. Thanks for letting me know!

There is now because of a class action lawsuit drivetrain warranty extension to 7 years 70000 miles

[@TheFalconx00]

i've left a few comments below describing my situation. But basically my valves were replaced about a year ago, but I kept burning at about the same rate, went back to the dealership. Dealer changed my oil and added dye (I paid for oil change), after keeping car for a few days dealer found my valve cover gasket was leaking oil. That was covered under warranty. So if your engine is burning oil something is off, it could be turbo or somewhere else.

[@jamesgerard2956]

This has been happening on my 2021 CX-9 since the time I bought it. They kept on having me bring it in filling up and then bringing it back. They would then tell me that the oil level has not going down at all. Today I received a notice about a class action lawsuit about valve stem steel settlement.

[@tommulchy1]

I just received this notice as well; I would like to know more information regarding this situation and just want Mazda plans to address this . The letter is somewhat confusing ?

[@nomercyriding]

Received the same notice today (coincidentally two days after the first time we saw the engine oil light). I will definitely be contacting my dealer to try to get the valve stem seal replaced.

[@miltonlejeune5738]

I have cx-30 turbo I have the problem as well and mine falls in the ViN range. Thanx for the info. I will be talking to Mazda soon. Mine seems to burn the quart 3000 miles. Further I’ve had my car at the dealer for service and was not told about the bulletin! Mine also looks overfilled. I expected more from my dealer.

[@john_ron]

Did Mazda fix the issue for the 2022 models?

[@neonnoir9692]

I've been tracking this issue and waiting for a fix before I buy. People on reddit say the TSB doesn't fix it. Affects 2022 models too. I'm so pissed, I want a Carbon CX5 turbo so bad but I can't mess with a turbo that burns oil out of the factory 😡

[@Ryan57Garr]

CE is a cool color, but not worth the oil burning issue, so stay away from 2021. I have a ‘21 Sig Turbo and it’s burning a quart every 2k miles. Otherwise awesome car. Get yourself a ‘22 or newer CX-5 Turbo. They look so good with the gloss black trim and they have the valve seal issues worked out!

[@Jussoparkours]

From Australia here, having the same issue with presumably the same engine as I don’t think they vary between regions, the Australian dealerships don’t want have anything to do with this and refuse to acknowledge the issues you guys are having in the states. At a loss what to do to get this resolved in our 2021 cx9

[@codeguy112]

2021 CX-9 Signature series. 24000 miles. Last year oil light came on two different times. It’s a lease under warranty. Brought back to service adviser and confronted him. He said nothing wrong a nd I said you’re a liar. Here’s the TSB about oil usage and valve seals. He said Mazda has NO FIX AT THIS TIME. He said oil level is very finicky and if it happens again bring the car in so they can document it and fill oil for free. So now I have to bring car in every so often is an inconvenience. Too bad because we were thinking of buying it out?!

[@O5rx8Mazda]

I had the oil light come on before my first oil change just shy of 5k miles. After that, I switched to amsoil, and now my consumption is 1/4 of a quart every 10k miles.

[@JosselinTorres-c1l]

Is this happening to Mazda CX9 2018?

[@TheFalconx00]

Bought 2021 GT with 8k miles 6 months ago, now I am at about 16k miles. I had my valve stems replaced under warranty 2 months ago under that TSB (prior to that twice low oil popped up twice). After the repair in 2.5k miles I burned through another 1.5+ quarts. After topping off I am suppose to bring it back after 1000 miles so dealership can measure rate of consumption again. My dealership adds about .5 above the max line. So in my case valve stems replacement didn't solve the issue. Could be Monday morning engine build? or piston rings? Who knows. Not happy at all. Expected to keep the car for 5-7 years but now I am not so sure.

[@RandomEarthMedia]

Thanks for the comment. I had my seals replaced over a month ago and I am still burning oil. Sent an email to the dealership but no one responded so when I go in for my oil change I'm going to bring it up. I don't know why they even bother with a TSB if replacing the seals doesn't even fix the issue.

[@siddharthnarula4344]

@@RandomEarthMedia Did you find a fix for the issue?

[@RandomEarthMedia]

@siddharthnarula4344 I had my valve seals replaced and that seems to have helped. The vehicle barely consumes any oil now.

[@siddharthnarula4344]

@@RandomEarthMedia That’s great. How did you convince Mazda that it needs a repair under warranty?

[@RandomEarthMedia]

@siddharthnarula4344 all they needed to see was the code when they hooked it to the computer. Even though I had topped off the oil level, the code was still in memory and that's all they needed to approve it. Directly after getting the seals replaced, I did have some oil consumption and I thought the new seals did not fix the issue but overtime, it got much better so perhaps there was a short break in. Or something. Just recently went 5000 miles between oil changes and there was barely any oil consumed.

[@viktorzzz2124]

2021 CX-9 GT i just started having this issues too. It started with just breaking itll come on then off. But the closer id get to my 5k range the light would come on way more and stay on.

[@zeitck]

Great video. Isn’t the reason they are overfilling that the actual capacity is 5.5 quarts but the manual says 5.1 quarts? Or, are they filling 6 quarts? Just seeing your video, visually it appears to be 6 quarts or just shy.

I have a 2021 mazda 3 turbo , i have 93000 km on it, its been burning about half a litre , 500 ml-600 ml , every 7000 km since I purchased brand new, the consumption seem to remain the same amount, is it worth getting it fixed??? I heard people getting their fixed , and the problem getting worstttt, so I am hesitant, Any advice anyone

[@Ryan57Garr]

Any update on if the valve seal replacement fixed the issue? My ‘21 CX5 Signature is having the same issue. Light used to come on about every 4k, but this last time it came on after only 2k, so the problem is getting worse. Only 19k on my car and I’m religious about maintenance. Mine is scheduled to go in

[@RandomEarthMedia]

Unfortunately it looks like having the new valve seals installed did not fix the oil consumption issue. I noticed my oil level is still dropping after having the repair done. I emailed my service manager but have not heard anything back so I'll probably just wait until it's time to have my oil changed and I will bring it up then.

[@yournightmare9999]

Overfill can damage engine don't listen those morons. Drain oil to the top level. And better if you start change oil by yourself. That's why when you go to the dealer, dealers pour in as much oil as possible and then the engine takes oil. I changed the oil in the gearbox at the dealer at the beginning of this year and they poured in half a quart so the gearbox couldn't shift higher at 60mph. Than I check transmission oil level by myself and drain to the point and transmission start shift like before.

[@edstacks5254]

Just keep it til 100k miles... oil cosumption of a quart for 5k miles of driving is pretty normal even new toyotas do that without the valve stem issues😂😂😂

[@C-howard-youtuber]

Just curious- what do you mean "just keep it til 100k miles"- are you insinuating that there shouldn't be any major damage to the vehicle by overfilling the oil every 3500 miles or so until the car reaches around 100k miles? I have a cx9-2021 and having the same exact issue with my vehicle. I only have 30k miles. If I can overfill and not have any major problems for another 70k miles I will probably keep it cause I do like the vehicle a lot, but if it's just a ticking time bomb even after the tsb is addressed, I am inclined to sell it sooner than I was wanting to.

@VisualFarts I think the reference to the 100,000 miles is in regard to the certified preowned warranty that I have on the vehicle which covers the powertrain up to 100,000 miles. I don't anticipate any issues after 100,000 miles.

[@nazad89]

My 2020 cx9 has 42000 miles on it and just around 1300 miles before my next oil change this low oil level light came out. I topped it off with little over half quart and now in NY got my oil changed they put 6 quarts instead of 5.1 quarts. Should i be concerned because of overfilling or let it go since the overfill would eventually be burnt by the engine anyways?
