Tons of reports from the CX-9 thread at Mazda247 seem to imply that any 2.5LT engine from 2016-2021 is guaranteed to grenade at some point? Mazda even has a TSB issued, but no recall formally. Also what about about 2021+, are those engines confirmed free from this defect, or have we heard of additional reports.

It’s really frustrating that none of this shows up on Consumer Reports, JD Power, or reviewers, implying a reliable power train issue is out there in somewhat reasonable numbers (enough numbers, that Mazda issued out a TSB). Combined that will reports of Mazda not honoring repairs even just shy of the warranty puts a really sour taste in all this. I feel like a PSA/Sticky, like they did in r/CX9 is a start, but given how prevalent the engine is (Mazda 3, Mazda CX-30, CX-5, CX-50, Mazda 6), just feel like this should have way more attention that it currently does now.

Iunno, just ranting as a recent 24 CX-5 buyer, would have strongly re-considered if I had known that the 2.5T issue could go beyond the initial wave covered by the TSB.

    It’s probably one of the most reliable turbo 4 poppers out there.

    MY21 had oil consumption issues; but otherwise it’s pretty much a solid and issue-free engine. Turbo engines are mechanically more complicated and require slightly more maintenance than their NA equivalents but I haven’t heard of any 2.5T just grenade themselves.

    SkyActiv is generally considered to be a dependable range of engines/transmissions. Change the oil every 5,000mi and you’ll be good.

    Every CX-9 built since 2016 is guaranteed to eventually grenade itself? That’s honestly just a ridiculous and blatantly false statement lol

    All of the TSB’s out there shows that the issues were resolved mid/late 2021. Of course, only time will tell whether the powertrain issue will creep into the 22 or 23 as it just hasn’t been long enough.

    I have a 22 CX9 now with 25,000 km and I came from an 18 CX5 2.5 NA with a cracked cylinder head at 42,000 km (slowest oil leak ever as there were no other symptoms besides a burning smell in the cabin when the HVAC fan/blower was on).

    I knew about the potential problems of the 2.5T prior to picking up the CX9, but the other alternatives in this class were just too expensive for similar features.

    There’s not a single vehicle out there that doesn’t have issues . At the end of the day, I guess you just have to think positively that your car is not one of the “issue car” out there.
