There are lots of complaints now, I just had a fight with Mazda, and Mazda now own the CX-30 I bought, I drove the 2021 and 2020's all have terrible AC, I went down to 2019 Mazda 3, its better, but not good, all though that is now doing the same, its in the shop, after 250 miles from new, it started blowing warm air all the time from the passenger side of the car, and the AC turns off too soon now too, I don't know how you can drive a car under 50% throttle and accelerate at the same time, going home from work, its up hill, stop go traffic, I have no AC going home, its time to get class action law suite going against them.I'm not sure why you are defending the poor performance of this cars ac. I think my compressor is turning off because something in the software is telling it to as soon as the throttle is applied.
To be clear, I'm not measuring cabin temperature. I used a meat thermometer and the probe is 6" inside one of the vents. I'm measuring air temp from the vent. The cabin temp is much much warmer.
I will say this again, I can sit at idle indefinitely and the air temperature will remain at 52 F + or - 2 degrees. Also at a steady speed the temp remains constant. About 15 seconds after any acceleration the temp rises more than 10 degrees sometimes as much as 14 degrees.
If all Cx 30s are set this way I'm surprised there aren't more complaints about this.
There are a few more complaints in the evaporation problem thread though. It's hot and HUMID in Houston now. Perhaps people in dryer climates have the benefit of evaporate cooling (simply having the air blowing over the skin will have a cooling effect) and the rise in temp is not as noticeable. We don't have that advantage in Houston. Perhaps it's just my car and a few others?
I work in law enforcement as a department Mechanic, I know of, no cars, that turn of the AC under anything less than, wide open throttle, I will be fighting Mazda and going back to Kia, don't bow down, fight them, I have hypertension, and must watch my body temperiture, and my best friend as A.M.L cancer, and she must keep her temp down too, a good Attorney will jump all over that, not fit for purpose, not a safe car for heath reasons.
Mazda says there is a software fix coming out around October/November 2020. I will wait until the end of this month, then go for a legal buy back.
