I have noticed that Subaru and several other AWD manufactures offer stability control that seems to work only with leather seats (they don't put it in cars without leather seats).
I am not an engineer and don't understand the details of implementing stability control but perhaps someone could explain the integration of leather and certain types of stability control. If leather is necessary for optimal operation of stability control would it be possible just to wrap the controller unit in a leather case or perhaps "spoof" the stability control computer with a signal that mimics that given out by the leather seats?
I guess that there is a fix in the works since it appears that stability control will be mandated on 2012 model year and after.
