My wife and I both drive our '03 Yukon XL so the memory seat function is a must. However, about a year ago we noticed that when you select your memory number, the seat wouldn't move forward completely to the saved setting. You could adjust it using the seat forward button and save it and it would work correctly for a while and then it would "loose" it again. Every other part of the memory would set correctly except the forward position. So now when you hit the button, you have to wait for everything to set and then move it forward with the seat button. If you try to move it while it is setting other postions (seat back, lumbar, seat tilt, etc.) it will stop those functions so then you have to do it again.
