The 2.5 engine shuts down 2 cylinders during cruising...

I love all my previous Mazdas..

But this "FEATURE" will stop me from buying this car. I've bought 5 brand new Mazdas since 2012, and loved this brand for it's excellent engine drivability.

2012 CX5
2013 Mazda 6S
2) 2017 CX3 GT
2019 CX5 GT Reserve

I don't care how they sugar coat it. I'm not buying it. Unless I can disable it without going to the aftermarket 😡

Customers should have the option to disable this garbage.

If this is actually the case, it doesn't make sense to me that they would have a separate ECU programming for the same engine.

Also, for my own interest, I am only interested in the top of the line premium package anyway... I like all the bells and whistles.

They can keep this one for now... NOT interested... not even for a test ride. :mad:

don't understand why you call it "garbage" some other manufacturers have been using it for years (Honda for example) on some of their engines.

This feature is also standard on the top GT model in Canada but there is increased fuel economy with this feature.
2.5L without - 9.9 / 7.7 (AWD)
2.5L without - 9.3 / 7.1 (FWD)
2.5L with - 9.5 / 7.4 (AWD)

There have been a raft of complaints regarding the intrusiveness of the cylinder deactivation on the Mazda 3 forums. I wouldn't get it either if I were buying a Mazda today.

It defies logic, adding a layer of complexity for no significant gain, that can only come at a cost in reliability and longevity. Its got me hesitating too. Just as dumb as the start/stop systems some manufactures are using. Luckily, my early production 2017 CX 5 does not have it. I usually only keep my cars 3 years/40k miles or so. I might chance it.

I didn't realize that they were doing this with the CX-30 but in all honesty it's not a deal breaker for me, especially if it's only standard in the top model.

Does anyone know if CDA comes with the FWD Premium trim in the US or just AWD Premium trim? Honestly, from what I've read, I don't want CDA and I can live without AWD but I'd really like to have the Premium trim.

according to the Mazda US website, it's a feature of the Premium trim regardless of the drive-train.

Yeah, I've see that -- just trying to twist it into the reality that I would prefer (no CDA). The funny thing is that the gas mileage for FWD with and without CDA is reported to be the same (rounded to integer numbers) so why would they even bother with it if there were no significant improvement? Arghhhh ...

Think his point is it has been used reliably by other manufactures and even Mazda for years. But I wonder if he is aware of the problems the new 3 had with it even though it was supposed to be proven technology. Some leading to total engine failure, later blamed on software by Mazda.
Am I right conwelpic?

Sorry, not following. Your post #4 doesn't list mileage for FWD with CDA. Are you suggesting that Premium FWD does or doesn't come with CDA?
remember this is Canadian info the GT model (similar to the US Premium model) is not available in FWD in the Canadian market.

don't know, it was just a general comment that came to mind when I read the post.
