    Report back from Mazda dealer here in australia is that issue was also noticed in 2 other cars they test drove. They have notified head office and then mazda Japan so waiting to hear back if there will be a fix for this. For me the issue is too great a problem that I wont be just accepting and 'live with it'. If they dont fix this then the car will be returned under warranty as it is not what I paid for.

    i got a 2019 bought in march 2.0l hatch and my only issues that bother me are the blind spot monitoring are all over the place, can't be trusted at all, turn on and off randomly while no car in the back. And the cylinder deactivation when running on 2 cylinders and applyiny little trhotle, the car vibrates alot and it's very annoying. Don't notice anything when the cylinders turn off, just that there's always a lagg when applying throtle, like almost half a second of nothing happening and then the car "wakes up" and starts accelarating. really annoying even when taking off you have to be careful since the delay can make you stall the car.

    - If driving less than 60 mph on 2 cylinders (in cylinder deactivation mode), noticeable vibrations penetrate the cabin. If you have ever driven a car with a 2 cylinder engine before, you know exactly what I'm talking about. Vibrations disappear when all cylinders are activated.
    The only flaws that I have noticed so far in this car, I have the European version 2.0, what can be done to make mazda aware of this?

    Report the issue to Mazda Corporate. I guess you could also petition for signatures of those who are experiencing the same issue, with the intent to forward the petition to Mazda and show how widespread the problem is. That's about as much as the layman can do. When/if there are enough people making a stink about it, Mazda may address it publicly.

    The vibration from being in cylinder deactivation makes this car feel like a POS . It really is not great to be vibrating down the road. Answer from Mazda so far has been "Normal Operation" AKA we don't know why it's doing that

    lol Seth, even passenger trucks these days do not shake like this, in fact they are quite smooth. Maybe like one of the cube truck things. But I know exactly what you are talking about and I hate it. It's crossed my mind to rid myself of this car because of it......but how would you sell it. Tell there person : oh ya the shaking is a feature not a problem. From my research I think it is probably in their drivetrain software - it is too aggressive and activates at the wrong times. I have also had mine stuck in two cylinders. Real annoying. I have complained to both dealer and Corporate so I hope enough do the same and it makes it's way to Japan.

    It is INEXCUSABLE not to include a switch to disable cylinder deactivation, just like BMW does. That way Mazda gets the EPA/other credit, but allows those that don't want it to opt out.

    I did a 3 year lease on my CX-5, but will go back to Lexus if the CD proves problematic.

    Dammit, I*m eyeballing a 3 hatchback when the lease is up on my CX5, and this is the one thing that might have me looking elsewhere. Definitely gonna test drive the crap out of it before making a decision.

    I am in the same boat as you are, but I will be buying and owning for years instead of leasing. If you lease, the car would be under warranty during lease term and there is no worry of CD failure post warranty like owning one. I would pull the trigger if I were you.

    Just like this. Two buttons, easy to set every time in markets that would require it, or the vehicle can remember the setting.

    It is idiotic for them to lose customers to this. EASY fix.

    I highly, highly doubt they would do it, but I wonder if it could be added to a software menu in an update. It won't be, but I wonder if it is technically feasible, if issues with the system really did start to pile up.

    It's possible for sure. It's just a matter of programming. I'm more worried about legal problems. It's tested and approved with CD. With the system switched off, it's MPG will change. But during the VW dieselgate scandel VW reprogrammed, even modified existing engines. These fixes were approved. There's a chance a CD off option will be approved too.
