Hi, I'm a new member and have 2011 Nissan Versa Hatchback. I love the car but have one issue/problem. Wondering if any one else is having the problem. About 25% of the time when the vent (with outside air) is turned on with the lowest temperature setting it blows hot air. My Nissan service guy says that their field engineer is saying that there is nothing wrong and it is just taking the warm air from the engine and blowing it through the vent. This does not happen all the time. Any comments?
