2022~2023 CX-9s with Cracked Cylinder Heads?

[Vetteman]

I’ve seen all the stories about the 16 thru 20s with issues. I have a 2022 CX9 with 53k miles. Does n e one have a 22 or 23 model with a cracked head or was it resolved now? I have the opportunity to get an extended warranty as I come up to 3yrs of ownership in February.. Do not want to get to 90k miles in 2yrs then need an engine..Are there n e high mileage 22s or 23s that have been fine with no issues?

It was up to 2020, here is the NHSTA TSB link. You will have to copy and paste it.

There is one case that I came across on Reddit of a 2021 CX9.

I have a '22 with no issues, but only 31,000 miles. Only thing I noticed is that minuscule leak at the oil control valve.

For those interested if Mazda resolved the CX9 Engine issue: not on mine it wasn't. Purchased my '22 Grand Touring CX9 in September of '22 and at 19,500 miles in December '24, the engine light went on. The dealership replaced the head assembly and gaskets: leaking on cyl #1. Not a happy camper, but at least it was still under warranty and covered. Hopefully, Mazda will also include extended factory warranties to the '22 like they did with the prior years. I also have a 2019-CX9 that I received notification of the extension for.
