I'm about to get a 2022 Mazda CX9, and I'm wondering if the infamous oil burning affects models after 2021. Any insight would be appreciated

 

Welcome to the forum

The forums do not have accurate numbers and its not infamous.
Do you actually believe everything on the internet??

There is not one bit of empirical facts and exact numbers from a reliable and verifiable source to claim any actual number effected.
If it is a dealership I will state the same thing I keep posting name the dealership that says otherwise! As an authorized independent c contracted with Mazda for some warranty work I can access that dealership information and find out exactly how many oil burners they actually had!

Most member here on this and a couple of Mazda forums will likely tell you their good experiences with that model you are looking at!

 

Is this a fake TSB?

 

A bulletin doesn't mean all vehicles are affected by the problem described in the bulletin. Bulletins are for professionals to use to assist with information, process, and procedure. While the Internet may show dozens or even hundreds of vehicles with what may seem like a similar issue, the numbers are still minuscule compared to numbers of vehicles in service. Also, internet reports are usually claims. Rarely do you see verifiable documentation or get detailed info about diagnosis.

Bulletins are considered manufacturer communications. In the USA, NHTSA regulations require automobile manufacturers provide those manufacturer comms to the NHTSA within 30 days from the end of the month in which they are issued. The documents are then posted online and easily accessible. You have the right to read, post, copy, and interpret it how you wish by statute. Unfortunately, being publicly available leads to a lot of poor interpretation.

 

ok dude this is another way as I posted to ad to the “Disinformation “ found on the internet to support information reading from inexperienced and also not even reading what the “complete” TSB says

Look go re-read it again a few times then go re-read what I posted.

The TSB is not fake but it is also meant for Trained Automotive Technician. Clearly states that and it use of that information.

What DOES NOT show in any way exact numbers of effected engines only VIN and “Possible” effected engines.
For an Automotive Technician that works at Mazda should they do in-fact get an engine that fits the TSB that will know how to proceed and what parts will need to be replaced .

NOTHING MORE


btw that TSB had you read it was about supposed faulty vale stem seals not crack or head casting problems. But hey if you go on a hunt for that TSB look no further ,it has been posted along with yours several times.

You may even find what I found about the new valve stem seals to replace the suspected ones. 😂

now if this was about a Pinto I would agree not to buy one 😂

 

well stated

 

“btw that TSB had you read it was about supposed faulty vale stem seals not crack or head casting problems.”

The originating post didn’t mention cracked head. A design defect will eventually affect all engine but depends on use case.

 

I know.... and BTW I was one of the first in the US to actually get a set of the OEM replacement to compare them on a experienced and professional level. ROLMAO
So the real funny thing is I know some interesting NONE posted facts about these so called failed one and the replacements.
But as I am not the one to pull back the curtain I can state DIY or just owners like yourself that often and this thread proves it really have no clue about defects, and TSB in general.
The cracked head and the valve stem seals are 2 badly posted in number on the WWW and especially forums .
