Between 80-95 here during the last week in NJ and mine is working perfect. That was one concern I intitally had when I read about the AC problem some CX9 buyers were having.
...careful with those remote starters to cool or heat the CX 9....don't complain when the mileage goes down.....engine running for a while, less miles per gallon..
Picked up our 08 Sat, the weather has been 105 here in Vegas and the A/C cools the whole vehicle down fast all the way to the rear seats. We test drove the car when the weather was 110+ just to make sure that it would be adequate, and can say it is. And by the way, it is one of the quietest systems I have heard, love it so far.
