I also noticed the seats didn't feel warm after being remote started. That is because there is no weight in the seat so the cushion isn't being pressed up against the heating coils. If you turn your passenger heated seat on with no one in it... it will feel the same way... no warmth. The only way to really test if the remote heated seat feature is working is to remote start while you're in the seat. I haven't done this yet.
I agree with the rest of your issues. I'm having some problems with my memory seat as well. Seems to not always go back to where it's supposed to.
