Since new our '15 has been very slow to cool the cabin. I just passed it off as a new model. Well, 35,000 miles later in for an oil change and have them check it and low and behold the A/C was overcharged not just a little, a lot. They thought I had Freon added, but the dealer has done all work on the car. Anyway, after 3 1/2 years my wife is happy.
