Hello friends,
Raises the issue of the evaporation problem in the front window which is not full.
It can't be only my problem, is anyone else having this problem?
cx-30, 2.0L, 2020
Thanks

condensation can occur on the inside on any vehicle depending on the outside conditions at the time, generally opening a window slightly at the time will help in speeding up the process.

Hello again, further to the problem I presented here,
Now in the hot summer season that started with us I noticed that the air conditioner works for short periods of time and actually makes it not feel really cold from the air conditioner.
In my opinion, it is also what happened in the winter that the air conditioner breaks off sooner than necessary and this causes the build-up of vaporization on the window every time.
Has anyone experienced the same problem?

As for the air conditioner it sounds like you have it on auto, take it off auto and set your own temp's and fan speed to see if it only works for short periods of time

Hello ,I’ve only had my cx30 for 10 days but my demise clears the whole window and I was actually amazed at how quickly it did this , maybe something is blocking full air flow ? Hope you get it sorted

Just letting you guys know about Mazda's HVAC or Air Conditioner System.
This applies to all new BP Mazda 3 and your new DM Mazda CX-30.
With AC on therefore AC Compressor is on and working, IF you Hard accelerate or throttle position is 50% or higher your AC Compressor Turns OFF, so it will not cool until Accelerator Position is below 50%.
No this prerequisite is NOT adjustable.
The Reason why?, well Mazda tells their dealers the reason is to maximize engine power under harder acceleration, which is correct, but also In My Opinion it also protects the AC Compressor at high RPM.
Everything today is lighter less robust and more efficient (fuel economy/weight wise) but reliability long term can be questionable (IMO).

I am struggling with this issue as well. I live in Florida where this 80-90+ degrees out daily and its been miserable. It doesnt seem to be just on hard exceleration in my car. I have tried to improve the air cooling by switch from economy to sport and back again to see if there is a difference but there is not. I have notified the dealer where I purchased it and now have been in touch with Mazda directly. They are away there is a problem but have not found a solution yet. It didn't sound like there was any headway on the fix yet.

It didn't sound like there was any headway on the fix yet. It doesn’t matter if your on economy or not. Its upon excelleration.

Should post this in the weak ac thread.. 🙂 I knew this was the case as I did in fact notice this under certain acceleration situations.

I have been at the Mazda dealer with this issue several times already, apparently the vehicle was designed this way, in order to give greater power to the engine during acceleration the a/c drops off and then ramps back up. I find this unacceptable in Florida and have been in touch with Mazda Corporate seeking a remedy. Its seems there is a bit of an in house dispute going on as the A/C side finds this a flaw, but engine design says it was designed to work that way to increase power and it not a problem.. there is no fix on the horizon as neither side is willing to work it out. It is too hot in Florida for me to deal with this nonsense, I am working with Mazda to get out of CX30 that I love and into another Mazda model that has normal a/c.

I bought a CX 30 last week and have the same problem. It's hot in Houston now and the air definitely starts blowing warmer when accelerating, even moderate acceleration below 50% throttle. In stop and go traffic I cannot keep the car cool. Really aggravating.

Seriously I would just return it! I’m so over this issue! I just test drove the CX5 yesterday and it has a/c seats so I proposed they put a/c seats in the CX30 to help with the weak a/c but apparently that’s not available for the CX30. I won’t last a whole hot summer in Florida with barely there a/c!

I'm in Buffalo New York definitely not a tropical climate and I have the same issue. It just randomly will get warm when using the air conditioning I haven't related it though with acceleration but I'll try to pay attention to that.

Current CX-5 is OLD generation, can not compare to CX-30, apart from some engine and trans parts everything else is all different.
I* will repeat what I said before, make certain the cars air flow is on Re-Circulation not on Fresh.
Keep your Throttle Position Below 50% so AC will work.
Above 50% is fast in 5-6th gear, accelerate gently until you get used to the cars system.
It is only defective becasue it is not what you are used to, I can tell you most if not all brands are and will be doing the same, for many reasons.

This is true .. I had a ford ranger Years ago it was a 2004 and under certain throttle situations the AC would for a very short time would cut out.. and it was normal.

Sure I know that I need to put the airflow on recirculate for maximum cooling. Took a drive this morning, it was 87 degrees and cloudy. I noticed the air was a little warmer shortly after accelerating but it was still comfortable. Driving this afternoon while 97 degrees and sunny outside it was getting unacceptably warm while accelerating. It's hard to judge where the 50% throttle position is but I can say I was being careful not to go over 2500 rpm while accelerating so certainly very moderate acceleration. Sitting at a stop light or driving at a steady speed the air is quite cold though.

I just posted a video in the Weak AC thread in the complaints and issues section showing the air temp rising 12 degrees F every time I accelerate. I was driving slowly in my subdivision and the video clearly shows I was not close to 50% throttle. Hopefully this link will work
Weak A/C?
