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.
