Considering buying a Mazda CX-30. 2022's are available now but have to wait for the 2023 to be released. Both the 2022 and 2023 have the same engine (2.5L DOHC 4 cylinder) but the 2023 uses cylinder deactivation. Supposed to get 2mgp better gas mileage with cylinder deactivation. Any issues with engine wear, longevity, etc. associated with cylinder deactivation. Also any general thought on Mazda products?
Cylinder deactivation will cause the engine to wear out more quickly. Check to see if that "feature" can be disabled.

This is a detailed post on cylinder deactivation. But in short avoid it.
One would think car makes would solve the cylinder deactivation problem by now. Or maybe there is no incentive to solve it.
It was a bad idea when GM introduced it in the 1981 Cadillac (as far as I know the first mass-produced car to use that technology), and it is still a bad idea today.
Judging by Mazda constantly adjusting part numbers for the cylinder head - it sure seams like they’re having issues with it.

But as far as owner-reported engine issues, pretty much all are abound extreme oil consumption on the turbo variant - pretty much nothing about the NA.

TMK, Toyota has stayed away from such technologies, which implies that there hasn’t been an adequate solution by Mazda, Honda, or any of the car makes.
One would think... Thanks All for the input. You've confirmed what I already suspected - stay away from cylinder deactivation technology. Thanks again!
