Vibration at Idle (2022 CX-5)

[LACX5]

Does anyone experience a slight engine vibration or shudder whenever your air con compressor kicks in? Is this normal for Mazda 2.5L engines to behave this way? The vibration can be felt while waiting at stoplight or stuck in traffic with the transmission in Drive. Needle on the tach would also swing between 700 and 500 RPM. Car is 2022 model year. Normally a solenoid is used to increase engine RPM whenever the compressor is on to compensate for the extra load. This would eliminate any vibration. Also special rubber mounts are used to decrease any vibration from being sent to the passenger compartment. Not sure if Mazda and the 2.5L engines are built the same way.

It is not normal for what you are describing on the Skyactiv engine and MAZDA did do a great programing with the ECU. I have personally looked at many of their mappings. Funny today I was actually in the process of changing my fan temperature mapping and may bump the AC/on engine idle a tad as well.
You may considerer depending of the miles of your MAZDA need to pull your MAS and MAP and spray some electrical cleaner on them. Also the fuel you are using may have changed formulas which always effect the running of the engine. There is some slight adaptive characteristics in the ECU but I am more incline to think about the sensors in your case.
I have close to 40k miles and running the AC the engine is just as smooth as not. The other interesting thing is you did not mention the use of defroster and the idle condition. Because the AC actuates during that stage you should be having the same noticeable engine anomalies?

100%. Had similar issues with the car shuddering when stopped in drive. Tried spraying it with a cleaner but the problem persisted. Replacing the MAS resolved all issues, got rid of the check engine light too.

I have noticed a slight deviation on our Turbo but nowhere near 200 rpms. It's very slight. Our NA non CD CX-5 does not waver at all.

200 rpm change at idle is not normal.

If theres no code on the dash - youre ok - mine never did that however - yet 90% of my driving was freeway - it should compensate - as MAZDA engineers have addressed the issue - Your Car is brand new - break it in - takes a good 20-25k mi - drive it - stay cool -

Normally a solenoid is used to increase engine RPM whenever the compressor is on to compensate for the extra load.

I wonder if they still use this method, considering that possibly the ECM could do the same thing with code. I think Mazda has liquid-filled mounts, sometimes they fail.
