My CX-5 was a 2017, prior to the introduction of the cylinder deactivation feature.
I arrived at my conclusions after considering all the evidence and my first hand experience. The vehicle was throwing no codes, and there were no stored codes when I checked with a reader. To me it simply feels like ignition timing retardation only on a much more severe scale. I should have recorded a video of it but I don't believe in handling a phone while driving. I could floor the car in first gear and it would take 20-25 seconds to reach the red line which is about 5 times longer than normal.
In the older thread a couple of people called me out for not taking the vehicle to the dealership and making assumptions about what the vehicle was doing. I suppose that was a fair criticism when I look at it from their point of view. I'm kind of an outlier in that most people who are complaining own the turbo, but I experienced it in the NA version. I was (and still am) just very confident that the dealership wouldn't find anything. They would check for stored codes, find none, and tell me the vehicle was fine. Maybe I could have arranged to have them keep the car and drive it when it was very cold out, but again I know where the discussion would go. They would tell me they would send Mazda their findings but couldn't do anything about it that day because there were no codes to diagnose the issue, and then I'd never hear from them again unless I nagged at which point somebody would blow smoke up my butt and say Mazda couldn't determine a problem and the the vehicle was "normal."
All of that's an assumption on my part, yes, but it's very likely how it would have gone down. So I spared myself the hassle and didn't try.
I don't really have a stake in it anymore, but I like to keep up with this discussion because it's interesting and I want to see what becomes of it.
