Never had any issues at 110000 miles and still going strong. Yes, I use 100% synthetic oil and still running new. I still get 40mpg with cylinder deactivation on the highway.
It's extremely annoying, me being a mazda fan and planning on purchasing a cx5 in the near future, that cylinder deactivation is standard on ALL trim levels for the 18-20 years. If I had enough money to buy a brand new 2021 I would, but part of the reason I love mazda is because they and toyota have EXCPLICITLY avoided some of these dumbass new technologies like tiny engines with turbos/ direct injection (oil dilution problems eg honda and gmc), cvt transmissions, etc. They are about quality and reliability, but this REALLY shakes my confidence in their engineering. It just seems like a ticking time bomb, and for what, and extra 1 mpg? Cmon man
I don’t think it is a ticking time bomb. You always have the option to purchase a 2.5 turbo engine without it. You’re right the 1 mpg increase is not worth it for these technologies. However as long as manufacturers have to meet the demands of politicians they will keep creating and using these types of enhancements. I don’t think you will have any problems or disappointments with any CX5 with cylinder deactivation.

@@JSS Touring 2020... There is a bunch of features still don't know... I learned today what is the Advance Smart City Brake. Great video, I just clicked on subscribe. Greetings from Seymour, IN.
I took the turbo engine option to avoid Cylinder Deactivation. There are easy ways to clean the intakes with a spray, so the turbo doesn't scare me at all.
Is there any way to deactivate this "feature"? I have only read horror stories about cylinder deactivation and with the new 2021 models coming out with this "feature" missing completely, doesn't really instill any sort of confidence with this technology.
I'm not aware of how to deactivate it. I think they discontinued it for 2021 because of increased Turbo offerings, and it didn't really have the fuel economy payoff they were hoping for.
The 2021 model year with 2.5L non turbo engine still has this feature. Checked on the Mazdausa.com website. Its the turbo engine that doesn't have this feature.
I have this technology on my 2019 Mazda 3. Had an issue with it for over a year. When it would go into two cylinders at 80-100 kmh it would vibrate the whole car and create a low rumbling sound. There was a fix recently released with updated radiator mounts and software which has pretty much resolved the issue
@@JSS This is not correct disconnection of two cylinders. We can see that the valves are closed. The cylinders are under compression. And this means that compression slows down the engine and the car. It's like a retarder in a truck. To properly disconnect the cylinders, you need to open the valves. This is called the decompression mechanism.
The cylinder deactivation is only useful on highway when driving moderate speed. In and around town, it´s always more useful to shift into the next higher gear to have lower revs.
@@a124as Just shift like the suggestions of the car. You will never see 2 cylinder mode, but instead always shift into the next gear. Below about 1600RPM the 2 cylinder mode doesn't work.
Has Mazda addressed the cylinder deactivation issues that were in the 2018-2019 CX5? Out of the 2.5NA and the 2.5T, which do you think is more reliable long term? Thanks!
I think they’re both pretty solid. Typically turbos would fail before anything, but so haven’t seen any signs of that on these engines. I would say you’re pretty safe on both. I haven’t heard of any issues with non turbo since the recall. I think they fixed it.
Cracked cylinder heads are popping up more frequently on these motors with CD. My '18 is going to the dealer in a few days for repair. Starts with burning smell and mild smoke. Mine has oil all over the exhast side of the engine
drove a 2019 cx5 today. I was looking for the screen that shows the fuel economy monitor but mine only shows bars that go up and down as you drive. Im in Canada so maybe the lcd is not programmed to show the car with cylinders as it does in your video.
But does it only deactivate cylinders 1 and 4? It seems to me an unwise choice, ford has the deactivation on all cylinders of the 3 ecoboost and deactivates a different one each time to have a degree of use of the piston sky homogeneous among all.
With this information of cylinder deactivation causing wear and tear due to its on and off. Would you say turbo engine’s are better in terms of durability and life span of the car??
Is it possible to disable the cylinder deactivation? Because it will destroy the engine as shut off cylinders will be cooler and won't reach the correct tolerances, therefore they gonna wear out much faster and result in serious oil burning and loss of compression.
Most people rely upon the car moving slowly with the right foot not on the gas pedal at all. This is particularly true when parking, for example. I think this is called the "idle speed" and is very helpful when you want to move very slowly into or out of a parking space. Does the cylinder deactivation permit a reasonable idle speed or does the car not move at all if your foot is completely off the accelerator pedal?
I have a '21 Mazda6 Signature. The only time I notice the deactivation is backing down my long, flat driveway. When I get in and shift into reverse it doesnt hardly move at. If I give it just a smidge of gas it goes a smidge faster - but holds that speed for a good 100ft until I have to brake.

It probably won't wear evenly over time, and you'll have serious oil consumption and a vehicle with no resale value. My prediction is a lot of people with these vehicles will lose way more in depreciation than they saved in gas.

Thanks!
I don’t think the deactivation feature will have any real bearing in reliability. I think this engine is good to go for a long, long time.
@@JSS I hope so and trust that Mazda's engineers know they are doing. I have great respect for japanese people and the way they do things.
I have just put a deposit in for one today.
@@JSS do you know if the newest 2023 2.5L NA engines still have CD? They seemed to have removed it from the spec sheet
Putting those cylinders on/off adds tear and wear on cylinders and engine. That’s a dumb idea because effects car reliability. Who wants to deals with car issues? Specially inside the engine? Very expensive to fix of course if you manage to fix.
Agreed. We were considering the CX5 for our next vehicle. But we keep our vehicles 10-15 years. I just see this as a problem waiting to happen long term.
@@joncook8548 I was looking to buy a 2018-2019 CX-5 but I got last week a 2017 CX-5 Grand Touring with 34.000 miles on it. 2017 model doesn’t have on/off cylinder feature and features are 99% identical and exterior is the same. Avoid if you can 2018-2020 models.
I hate it, and probably won't get a NA engine in my next Mazda, turbo only. My 2017, CX-5 is still running perfectly.
@@derricksearles610 Same my 2017 CX-5 grand touring. Can’t be happier!
Horrible idea. Creates uneven engine wear.
I can't imagine the MPG of Prius if Toyota did the same. lol
Cylinder deactivation leads to shortened engine life. I don't care what they call their "new" technology, facts are facts. No thanks.
Yeah ok. We get it. Mazda isn’t for you. Move on.
Mazda’s implementation of cylinder deactivation is completely different then the god awful stuff that was put in Chevys for years. Chevys literally had the crankshaft change shape and it couldn’t last over time. Mazda simply keeps the intake and exhaust valves open and stops injecting fuel.
@@romancenturion8 they don't. They use a switch in the telescopic lifter that makes the cam move the lifter instead of the valve.
It's pronounced Mahz da, not Maaaaaaz da.
It ruins engines
