While driving for about an hour doesn't matter what speed it is all of the sudden there is hot air coming in from the front feet space by the pedals, you can feel it in passenger side also. ( ac is on and blowing cold air and the recirculate button is on) upper vent blow cold air while this happens. i had taken it to dealership to take a look at it but the computer doesn't show anything so it has not been fixed. in all the years i have own a other vehicles i had never experienced anything like this so this is not normal and very uncomfortable when you are wearing open toe shoes. i asked dealership to drive it so they can experience so they will take a look at it again when the other recall part comes in. i notice it since the first week i took ownership.
