The one issue we never resolved in our MKZ before we traded it off was the flaky memory seats. We constantly lost position 1 altogether, it would just go away about every 4th time we'd start the car. And position 2 crept backwards little by little, and by this I mean when you'd shut the car off and the seat would go back into the easy exit position, then on restart, it would come forward but stop like a 1/4" back from the saved position. Eventually, after about 4 times, you'd be noticeably further back and have to reset the position. The warranty had run out and so I didn't want to pay to have this diagnosed. But it was an annoyance that contributed to our lack of connection to the car. Never had those kind of problems with our 2014.
