For what it's worth, mine heat up quite quickly and I have to drop it to level 2 or 1.
Also, didn't read every post - but ECO Pro mode will reduce the heating output of the seats, so if you have it on level 3 [highest] and you're in ECO Pro mode it will not be as hot as the seats would be at the same level in say comfort or sport mode.
