I’ve noticed a few people have issues with the memory seats, not sure if some of you are aware but if the doors open or your not sat in seat you just need a single press but when the doors closed you need to keep button pressed to move to saved position.
I think it’s a safety feature so you don’t have seat moving while driving and if seat settings have maybe been changed and you jump in and press button you don’t get squashed against steering wheel if using a single press, etc. Hence why it needs a constant press so can be stopped immediately.
