I've had my diesel since January and the seat doesn't move back when the car is in park. The memory button sets my settings and I rarely touch it. One thing, make sure the dealer filled up the DEF and other fluids. I ended up with only part DEF filled which caused some problems. TomHey everyone so I finally got my limited diesel today. Only one thing I dislike so far. When I put the car in park, my driver seat moves all the way back. I've never had a seat memory system before, so I'm not sure if this is normal or not.
