2021 grand touring non turbo. Absolutely no problem with CDA. Completely seamless with no change in smooth cursing in town. And in country on flats giving up to 58mph.
Our 2024 doesn't have CDA or i-stop. It was manufactured March of 2024. They said they stopped putting both in the Cx-5's around October/November 2023 due to parts shortages. Maybe so, but I can't help but believe they realized there was a problem with it.🤷 I'm really glad they're not there. That's one reason I bought this particular year model and build date.👍
If I didn't already own a 23 Mazda , i would be afraid to buy one after watching your experiences over the year. (Knock on wood. No issues at 6k miles).
This guy has a ton of time on his hands and the slightest hint of a hiccup gets a full lecture. Did you see the fuss he made over the exhaust smell of a car near him?
I have CX-5 2024, 2.5l 194 hp, euro specs wit only 7k miles on it and it has that jerky thing that drove me nuts on one of my longer trip. My wife says she cant feel it as a passinger but I can. Now, not to say that it is unberable but for brand new car I was a bit unnoyed. After a while it seems it become smoother or I got use to it but I know it could be annoying. On Mazda forums there are comments that will go away after I put more miles on it. Anyways I love this car, and I still enjoy driving it!
Honda and GM both have infamously tried cylinder deactivation. Neither brands have perfected the technology and long term durability is definitely of question. Any system that interrupts normal combustion, besides causing an imbalance can lead to uneven wear and lubrication issues. One of my favorite CZcams channels is "I do cars" where a mechanic tears down destroyed engines and he has had some pretty glorious destroyed six cylinder Honda engines that had this horrendous feature, and it is obvious which cylinders get deactivated... but maybe Mazda's system is different, better? I also question Mazda's use of direct fuel injection instead of the more reliable port fuel injection, because of the increased carbon buildup in intake valves leading to more expensive servicing down the line, negating any fuel savings and performance advantages.
Please be more precise in your title. I can see on the flow control you don't have a mild hybrid. I have a 2024 CX-5 gasoline non-turbo 2.5l mild hybrid. I haven't driven it too much yet but did try cruising and accelerating and I haven't felt any "kicks". i-Stop is also quite smooth, works pretty well. Though I believe the mild hybrid helps a lot with that.
CX5 2021 - no such such issue with CDA. I feel a little jolt on switching jears when transmission is "cold", ex. switch to 2nd gear on parking serpantine in mult-level garage. Does sport mode turning CDA off? - can't find the answer here
I have a CX3 and it's moody, but overall drives great. One day it's driving smooth, the other day a bit jerky, one day faster and eager, the other a bit sluggish. It depends on your speed, gas quality, tires, if you have the AC on, wind gust, driving habits will also change the built in algorithm response, how you press the gas pedal, the temperature outside, if you have Turbo, have sports mode on, driving on flat vs hilly roads, etc. So I assume the jerkiness might be due to the timing belt slightly slacking or slipping from cylider deactivation or it could be just software needs update
I have a 2024 CX five GX, which is the lowest trim level here in Canada Is manufactured in September 2023 I bought it because according to the Mazda Canads website, the two lower trim levels did not have cylinder deactivation or I stop But I found out once it came in, it did have both of them. Idiots! Since I paid a nonrefundable deposit? I was stuck with it. I detest them both! It’s really a pain in the butt to have to keep turning off I stop every time I turn on the car, because every mechanic worth his salt has said that a it is really hard on the engine in the long run As well, just like you ,every time, the CDA kicks in or out, I feel like the engine is faltering, slightly, like you said, or missing I usually only notice it when I’m going between 70 and 80 km an hour over a long flat stretch I’m going to try just using the car in manual mode and see if it does the same thing I’m hoping that perhaps CDA is bypassed in manual mode but I guess I’ll find out
Own a 2023, mine does it along with a jerky trans unless you're really gentle on throttle. Mines also starting to have lifter tap on cold starts which I recently found out is a problem dating back to at least 2018. This was my first Mazda after having it be bragged up to me by friends & coworkers, seriously thinking on trading it.
Glad that my 2022 CX-30 doesn't have CDA or Stop/Start (iStop). Those are deal breakers for me in a vehicle purchase, & that sort of problematic engine tech is only around due to fuel economy regulations pushing automakers into hit certain average MPG numbers. The end-customer pays the price, however.
My 2021 is jerky, particularly when accelerating at very low speed. Sometimes it’s a hard jolt. I took it back to the dealership and they said I needed a new transmission (at 68,000 miles). They replaced the transmission, and it’s still doing the exact same thing.
Co-Pilot AI states that CX-5 trims equipped with a turbo do not include the cylinder deactivation feature. So name your poison, I guess. You can still get a Toyota RAV4 without a CVT and without cylinder deactivation. It does, however, include automatic start-stop (which can be turned off after starting the vehicle).
I've got Mazda CX-5 2019 non turbo. I'm still not sure if my Mazda has cylinder deactivation. There is no graphic for cylinder deactivation in the system settings. Do anyone knows if 2019 model year has cylinder deactivation?
I'm beginning to think you lost your marbles. After 2021 there is no issues with cilinder deactivation. I have 2022 mazda cx5 with 30,000 miles ! No issues. Maybe you fart when you get that jolt.😊
@@batira not ready usually is talking about the standard batteries condition to run stuff for iStop. I don’t believe your battery is charged enough for iStop to function. It may also be the reason for the jerkiness of CDA.
@fisherbrown903 Mazda was rated #1 by Car & Driver in 2021. Also, Consumer Reports rated Mazda the best a few years ago. I'm also less than thrilled with CVT transmissions. I could go on and on...
CDA seems like a disaster in the making. Two cylinders will wear out faster and throw the engine off balance. I was just looking at new CX-5 and now I need to find a vehicle without CDA.
You misunderstand how CDA works. It merely cuts fuel delivery and doesn't affect engine speed. All cylinders keep moving at the same rate, but the total power gets cut.

My wife's 2021 CX-5 had a seemless CDA as well. Not so with this 2024 though.

But both “features” returned in 2025 (per spec. sheet on Mazda website). I bought a later 2024 CX-5 for same reason.

Good to see a review of CD. It would be a deal breaker for me.
That's not typical issue as we can see. On my GT 2021 CX5 I doesn't feel any jolts 🤷♂ some engines doesn't have it as I've read it correct.
In my 2022 Mazda 3 (manual transmission), cylinder deactivation is smooth when it activates/deactivates, but... at lower engine speeds (
Custom programming is not allowed. The dealership will laugh behind your back at such a request.
@@VacLab All the more reason to ask then.

You need an UPDATE on the transmission firmware. That’s a known issue for mazdas, and there’s even a bullentin for that
mayb didnt replace transmission
Is it Mexico or Japan?
How much did you have to pay for the transmission? I'm basically at 60k miles and transmission I think isn't covered after 60k miles.
Did you pay for the new transmission ? 68k miles is basically out of powertrain warranty.

If the animated grapic can't be found, you don't have CDA.

*Does the sport mode cancel CDA? -Does running the A/C cancel CDA? Is it true Cx5 2024's built after Nov. '23 do not have i-stop or CDA?*
@@thomasfarrow7053 Running the A/C doesn't cancel the CDA.
@@vlreviews Thanks !
@@thomasfarrow7053on the CX5 the 8 character on the VIN will tell you if it has CDA or not. If VIN has a M it does, if it has a L it doesn’t
Just wondering, if running your car in manual mode, bypasses CDA
the same question is about sport mode
Battery status is “Not Ready”
It shouldn’t be going into cylinder deactivation. So something is going on.
That's the standard battery, which I think has nothing to do with CDA. The mild hybrid battery would, but it seems he doesn't have a mild hybrid car.
@@batira not ready usually is talking about the standard batteries condition to run stuff for iStop.
I don’t believe your battery is charged enough for iStop to function. It may also be the reason for the jerkiness of CDA.
does cda improve fuel economy?

Y didnt you buy honda or toyota?

Good luck with newer Honda or Toyota vehicles. Quality & reliability isn't what it used to be.
