Found little smoke (or moisture) from air vent while air conditioning was on 1st level and outside temp was around 82 F during one of the trips today. Since the smoke had on oder and it was gone after next start, I may ask dealer to look at it later together with the other problems I encountered earlier. Just wondering whether you guys had similar experience.

That may be condensed water vapor due to low fan speed setting. This is common if fan speed is low and outside humidity is high. This does not explain and smell though.

Have anyone experienced any air conditioning issues? I test drove a CX7 on a very hot day, around 96F, and the air conditioning had some problems keeping the vehicle cool. It took a long time to cool down the vehicle.

It's been around 100F here ever since I picked my CX-7 up, and I've found that the auto A/C works acceptably well in recirc mode. (Actually, I originally set it to 68F, but found it got too cold! - 70 is my sweet spot, apparently) Sure, it takes a while to cool down a hot interior (mine's black) if you've got no sunscreen and leave the windows closed, but I would expect that with any car.
What's got me puzzled is that when recirc is off, I've discovered the A/C is completely useless. I've enjoyed riding around with the recirc off and sunroof cracked in every car I've ever owned, but when recirc is off in the Mazda, it's unbearable on hot days. It's all very ironic since the owner's manual stresses two or three times that "recirc" should only be used for cooling down the car and that the "normal" M.O. should be with recirc off.

Compared to a lot of other vehicles I've driven, the A/C in the CX-7 is weak. On really hot days, in rush hour, bumper-to-bumper traffic, the A/C, even in recirc, won't cool the CX-7.

Not sure it is normal or ... I found warm air from the air vent even though the temp control is on coolest (without A/C on) after the car was driven and stopped for a while (Engine is still warm). You can obviously feel the air from vent is much warmer than outside and usually it lasts about 10 mins or so. Or you can turn on A/C to get rid of it. I believe that might have impact on A/C performance if your engine is warm due to previous trip.

I have a Mazda3 and have the same issue. My car does the same. So Mazda hasn't learned from the 3 A/C issues and it appears the cars are the same in regards to the Weak A/C.

It actually got cool enough for me to turn A/C off today and I noticed same phenomenon. I had never had recirc and A/C off together before. Thought maybe it had something to do with the cowl air intake being so close to the intercooler heat, etc., but maybe if it affects the 3, it is something else. At any rate, it was downright uncomfortable to leave the vents open, so I closed them and enjoyed the cool air coming in the open windows and sunroof. Weird.
