Patrick,
I believe we share the same seats (december delivery, waiting on next gens). Mine get very warm... I find myself turning them down on a trip. Not so hot as I'd start to sweat (or almost, literally burn me like an old volvo used to do) but very warm. I'd talk to Rockville and have them take a look.
Off topic- Funny thing is, I like my current seats (december delivery) and may not take the next gen seats I ordered once available... My lower back sucks and I find the current ones comfortable for it. I was in the Rockville service center last week (center console install) and sat in the next gens in one of the loaner vehicles. They definitely had a tighter feel (more like my wife's BMW 3 series) and I think look more sporty. Just may not fit me as well as the current seats do. I'm going to drive one of their loaners with the next gens in march when my car is in for a minor fix.
Good luck!
Lee
