Own a 2018 SE w/ Tech. Don't understand the erratic behavior of the driver's memory seat. My wife and I both drive the car. We use different keys and have personalized each so that when it unlocks the car, the seat moves to its saved setting. The problem is that the seat doesn't always change as it should, so we have to push the button on the side of the seat to get it to work. And sometimes, upon getting back in the car after I've just driven it, the seat will move to my wife's position. Can anyone explain what's going on?
