I, too, have Reynaud’s Phenomenon, and my Nissan Maxima has a heated steering wheel. In fact, my Maxima is a 2001 and SE model (the fully-loaded model). I also believe as of 2010 (maybe even since 2009) the Nissan Pathfinder has the heated steering wheel, though like the Maxima, you have to buy the fully loaded, high end model.
It has been eXACTly what I’ve needed for my Reynaud’s issues and I wouldn’t dream of owning a car without it now.
