Yes, I know what you mean. When I slide out I hit the controls and have to re-adjust when I climb back in. It would have been nice for DC to put an ON/OFF switch so things would not get screwed up.
I had thought about unpluging the connector when I get the seat into the correct position. The only problem with this is that it also is power for the in seat, seat belts. If power is removed the seat belts will lock up (fail secure). They do this for two other condition also: >. 5G loads and if you incline the vehicle over 45 degrees.
As far as getting the correct position in the seat there are certain rules. I can't not do justice here but can recommend someone who can. In a previous vehicle I was having the same problems: fatigue, and general uncomfort. I was talking to a shop owner who happened to be a race car driver and he sat me down and showed me up to properly setup the seat for maximumize efficiency. This really helped. So, get some help! I would start at a performance driving school. You may not like the position at first but it does make a big difference. It should give you better control and less fatigue.
