Wait was the car purchased in 2013 or 2018?

Right church, wrong pew. 2018 model has cylinder deactivation, no? Could be something going on with that.
Read it again, he saying when at a red light, and yes, a problem with cda is possible, he needs to define rough
If I am not mistaken, that idle RPM is a bit low. Should be similar to 2.0L SkyActiv engine which is around 700-750rpm.
My understanding is that Cylinder Deactivation only happens when cruising along, not when stopped. It would have been nice if the dash had a light to tell you when you are only firing on 2 cylinders. Our 2018 is smooth at idle, not rough at all. Take it to the dealer.
I agree with madar - a problem with cylinder deactivation is possible to cause rough idle. Your smooth idle with CD doesnt mean others are the same. Any failed components, or some software glitches of the CD can cause rough idle.I don't understand what this has to do with cylinder deactivation (uhm)
My response to their post:
I have cylinder deactivation and my idle revs are not low like theirs and mine idles smoothly.
Sounds like a simple calibration is required to their engine to get the idle revs back to normal range.
Correct. Only works under certain throttle input among other thingsMy understanding is that Cylinder Deactivation only happens when cruising along, not when stopped.

We might never know if cylinder deactivation was the cause or something else as they have not returned to tell us.
Yep, more moving parts in something that already has a lot of moving parts, not a trusting scenario IMO. Make no mistake, what Mazda has done with SkyActive engines is remarkable and they do it very well, and their version of CD may work better than the competition. I've driven the 18's and they are remarkably smooth, you never can feel when the switch off happens.I agree with madar - a problem with cylinder deactivation is possible to cause rough idle. Your smooth idle with CD doesn*t mean others are the same. Any failed components, or some software glitches of the CD can cause rough idle.
Idle control has its own feedback system base on multiple sources of information. It should adjust the idle RPM correctly by itself especially on a brand new 2018 CX-5. A simple *calibration*, if there*s a way, most likely can*t fix the rough idle or low RPM issue.
Mine is doing the same...Mazda CX-7. Have you by chance figured out what it is?My previous car had an extremely rough idle, so rough in fact that I had to put it in neutral every time I stop so it doesn't disturb the people around (and embarrass me in the process). When I bought the CX-5 I was really looking forward enjoying some shake free time idling on a stop light, but that has not materialized so far. I don't mean that is as bad as my old car but definitely not as smooth I as had hoped. It is not the warm up cycle it goes through at cold start. The shaking is very evident at all times regardless how wormed up the engine is. The best way I can describe is as having one of those cheap seat massagers (that basically only vibrate) turned to low setting. Putting the cat in neutral does not seem to help a lot. The vibration is not even either, it sorts of goes through short cycles with slightly rougher bumps feeling almost like miss-fires. I thought that I got some bad fuel, so I ran it almost dry and changed gas stations, but it made no difference. I know upfront that the Skyactive engine is not the smoothest out there, but many people report that they can not tell at all when the engine is wormed up and in idle. Anyone else having this issue?
It’s by design according to Mazda.Mine is doing the same ...Mozda cx7 ,
Have u by chance figured out what it is?
