I just tried to swap a 2010 sedans drivers seat into my 2011 and I want to hopefully save some headache for others. Although the cushions are the same and the seat fits, the connectors are not compatible between the 2 years. The 2010 has more connectors and wires (and another large white box my 2011 didn't have, could be difference in trim levels not sure). You can take the bottom seat cushion from a 2010 and put in a 2011, but the seat back has more connectors in the 2010. I was not able to figure out how to take the leather skin off the seat back and swap that, but if anyone knows how feel free to give your 2 cents. Also BE CAREFUL with the bolts that hold the seat bottom and the seat back together, they are torqued heavily from factory and are easy to round out (this applies to both my 2010 and 2011 seats). I dont have pictures of these bolts, but on each side of the seat there are 2 14mm bolts and those ones will round if not careful. That is all I have to add, connectors are different and easy to strip bolts. Also nice to have, a friend or two, food, heat (would of been nice), and a few free hours.
