So the RC has seat cooling problem? I'm going to test drive one in a few days, does this heating up happen all the time? I plan to get one but now I'll be testing this feature first.

It happens all the time as shown in the video I posted, and it is one band of the seat back. It is about 15 degrees warmer then the band directly below it.

Cause if it happens to both seats and almost every RCs (or all), I don't think it's a faulty unit, maybe it was designed that way?
The GS has big bands/sections and maybe the airflow is better than the IS/RC seats with small bands.

Do u think the heating element is turned on with the fan on that one band? Or is it just simply doesn't get the airflow like the rest of the bands? Like it's blocked on the inside?

I just don't feel like taking my whole seat apart to see how the fan works and why that one band is warmer.
When I take my car in for it's last free oil change I'll ask Service. and bring the laser thermometer along to show them.

I don't think the heating element is turned on for that one band, but that band and the one above it doesn't get the cooler air as it is father away from the fan. The seat bottom is the same way, as the front of the seat closest to the dashboard is a high temperature as shown in the video. I never really noticed it before as Summer in AZ it is bloody hot and nothing ever gets cooled down, especially if you are sitting on the seat.

I don't know about Lexus, someone said the GS only has 2 big vents, 1 for the bottom and 1 for the back. Maybe the RC only has 2 vents too and on some parts/bands it is being blocked by the heating elements, that's why those parts aren't being cooled.

It just seams weird that the band right below the top of the seat is the warmest, perhaps in fact due it smaller size or just the way the seat angles up at that point. Again, I really didn't notice it until I did the video and saw the difference.

When I brought it in for this the service department made a point out of the fact that the (other non-heating) setting is for ventilation, NOT cooling.
One worker at service mentioned that his IS, another that his GS have the same problem, as if i'd feel better about it, and drop it, after all, "misery loves company"

Response from Lexus Australia:
"We have checked for any Dealer Product Reports issued on this concern for both the RC 350 & RC F and I am pleased to advise that there is no reported concerns on this issue in Australia."
Are the U.S. cars built in Japan or the U.S.?

I'll try to explain. The seats are made by vendors and shipped to Toyota's assembly plant. The wiring,springs, covering,fans,heaters and so fourth are also made by other manufacturers sub contracted out. Each one of these vendors have various work shifts and man power. It's very possible that a process mistake was made on a specific shift and parts run. Thus affecting only a smaller number of vehicles. And it's also possible that this defect was not discovered and thus no recalls or TSB's issued.
Once Lexus finds the problem. And determines its this part or that part that is defective, they will in turn trace the part to the time and place made to correct the problem.
The hardest part now is getting Lexus attention to start the process.
