On the Mazda3 it was in the fuel monitor screen. I don't know if 2018's have this. I was test driving 2019's.
Is this the screen that gives you a instant mpg reading via a gauge readout in the info screen?
If so, there is a explanation. I have that same app in my info screen. It will be reading something like 30mpg or so and suddenly go to 40mpg. That is the engine going into a Miller type cycle. This is what was explained to me. You will see this once you get up to speed and are set for a while.
That's what I recall on the Mazda6 but on the Mazda3, there was an image with 4 circles with either just 2 or all 4 lit up. I didn't drive the CX5. From what I understand, each model and trim-level has a slightly different display format.
@PimTac: Can you feel when your engine switches mode?
@buster: As far as I know, it cannot be user-disabled.
Honestly, if I were in the market for a car now, that would not be a deal-breaker for me. The vehicles were in test markets for a couple years before going mainstream. I know several people with 2018 CX5's and they really like them. The dealers could not keep them in stock and same is true for the 2019. They've sold 300,000+ units with cylinder deactivation in North America. The actual number of incidents is (from what I understand) basically insignificant. Yes, there's a recall but, it's being fixed with a software update. There are units out there racking-up a lot of miles and if a disaster was going to happen, we'd know by now.
