Interesting. Mine does not have the ventilated seats, and it was one of the two features I had originally wanted. I miss having them from my Yukon and Escalade. My wife’s MKZ has them, and they work very well in her car. Since it didn’t seem to impact comfort in those vehicles, I had assumed it wouldn't in these. I guess I got “lucky” in not having them since comfort is one of my major needs. Interesting heads up for those that would prioritize the comfort of the seat.
