My 07 Aero, doesnt hold the the position I set it for. I adjust the seat then press memory/1 at the same time and here a chime- set. Then someone else gets in the car and moves the seat back so they can get in and drives the car. Next time I get into and press and hold #1, the seat doesn't adjust. Anyone else have this problem? Am I missing something? or is it a defect?
