Maybe it's just me but my A/C seems to take a long time, 5-10 mins, just to really get my air temps down to what I would call a cool level. 90 degree days. Anyone else experience this?

Get all your windows ceramic tinted, especially the windshield and pano. I had all mine done and it makes a world of difference on overall interior heat after being parked or what you feel coming through while you're driving. It will also immensely help your A/C run more efficiently and cool down your interior faster.

My old 17 Tacoma pulls down almost instantly. Even my 17 Rav did. The '50 does fine but takes a few minutes. The A/C seats seem to lag too. Prob need to schedule a service visit.

I do not find that mine takes any longer than any other modern car I have owned. It is a few minutes before it gets going. If I had to guess, I would say much closer to 5 minutes than 10 and maybe even less than 5 if it isnt super hot. I have not tinted any windows yet, but I do use a WeatherTech sunshade. From experience, tinting with ceramic film as suggested above does make a very big difference. I also start the car before I walk out to it from work and that helps a ton. Having said that, the seats do take some time to really kick in. 5-10 minutes is probably accurate for those.

For reference, today was I think 102. We have had as high as 108 in the 3 and a half weeks I have had the car. Our weekend is looking like 110+. Some tips that I have found helpful are trying to park facing away from the sun, use a sunshade if the car will be sitting for a while (like over 30 minutes) during the day, make use of the remote start (especially since it is app based, you get unlimited range), and tint the windows with ceramic film.

Yes! I've noticed this as well. I've also noticed that on hot days the A/C will blow warm at random times. I'm wondering if this is because the cylinders shut off to save gas.

One thing to consider is your area as well. Humid air is more difficult for an A/C to cool off. So if you are having a particularly humid year, that could explain some of the difference people are seeing. It certainly would explain our differing experiences. I live in a dry climate and my A/C seems to be fine. Not amazing, but good enough.

Another data point. Today we officially hit 115 (though it was likely a bit higher at my work). My car did not receive the remote start command, so I got into it with no pre-cooling. It did take about 5 minutes for the air to be cold and then some time longer (maybe a further 15-20 minutes) for the car to cool off and the fan to spin down a bit. But again, it was at least 115.

ive lived in the valley in Arizona and Texas. Both very hot places in the summer (and one muggy than the other) that challenge any A/C. My cx-50 is on par and maybe slightly better than any other vehicle I’ve owned. After sitting in the sun it only really starts to blow really cold when I’m moving. After 5-10 min it starts to get cool enough to stop sweating. Ventilated seats help but arent quite as amazing as id hoped for. When on “auto” it does the thing where the fan speed changes randomly, but not sure why.

overall, maybe there is some variation from one vehicle to the next that is causing poor a/c performance?

I have a 17 Tacoma and within 2 mins the air is refreshingly cold. My '50, not so much. So that eliminates the temp/humidity factors. I guess it's just nature of the beast.
Another consideration is the volume of air. A/C generally works by using the air in the cabin. A Tacoma will have significantly less air to cool and will require fewer cycles to achieve cold air. It really isn’t a fair comparison when the volume of air is so different.
Not necessarily trying to defend the CX-50. Just saying a pickup will always cool faster than a CUV that has more volume. The CX-50 does seem to take longer for many people regardless.

I'm a 35+ year a/c-appliance repairman. The avg temp drop thru an evap coil should be 20-25 degrees. The '50 is noticeably above that. I appreciate the volume to cool but the air discharged thru the vent should be cooler. Now...newer refrigerators have smaller compressors, smaller coils and use a LOT less refrigerant meaning longer cool down times. Customers always complain "this new unit runs all the time" but the end utility usage is still less than the older units. Welcome to technology I guess.

What did that cost, if you don't mind me asking?

I have ceramic 15% all around except front and 5% on pano. AC is a joke! It is 101F outside, you get into my '21 Lexus NX that has the same exact tint - it is high 80s inside. After Lexus IS started in Auto AC, within a 10-20 seconds interior is nicely chilled.
Mazda takes good 5 -10 minutes to match what takes 10 seconds in Lexus...... I guess the beauty of the Mazda is on the outside only :(
