I plan on getting out my multi-meter and measuring the current draw on low and on high. Do you have any idea what the current or wattage of the seats should be? My meter also has a hookup for a temperature probe. I will probably order the probe itself so I can talk actual numbers, "The wheel heats to XXX degrees", "The seat never gets above XXX degrees" etc.
I'd argue that people would be less litigious if the heat was maintained at a proper comfortable level rather than cycling between "OUCH THAT'S TOO DAMN HOT" and "OFF".
