2008 4.8i with comfort seats

I'm having a problem with my passenger seat occupancy sensor. I get a passenger seatbelt warning, even when no one is sitting in the passenger seat.

First question....is this car part of the occupancy sensor recall to replace the mat?

Second question, if it's not part of the recall, (which I don't think it is,) has anyone had any luck getting this done as a goodwill repair?

Finally, can someone help me with a part number for the sensor mat? I can't seem to find this on RealOEM. I think I need the whole seat cushion, but not sure.

Thanks
