I had a 2012 Lexus ES 350, and I could definitely feel the wind come out of the seats. The seats cooled remarkably well. I now have a 2016 Lexus ES 350 (with every option available). I agree that the seat coolers do not work well; they definitely don't work as well as my 2012 model (if they are working at all). I just bought this car 1 month ago, so when I get my first oil change, I will have them take a look. However, I'm sure they will say it's working fine, but I will give them the benefit of doubt at this point.
