Latest software doesn't make a difference. I have the same issue with the auto comfort setting and just upgraded to 13.38.
In my case, the heated/vented seats do not turn on when the vehicle is started. Some of you have stated that they DO turn on for you even though the setting turns off. I called and spoke with uconnect and was told the heated/vented seats are activated by that setting and the outside temp (above certain temp for vent, below certain temp for heated).
Right now, northeast ohio weather is in the middle of the temp range where neither heat or venting would apply so I was waiting to see if what they told me holds true when the temp drops a little more.
