Congrats and welcome to the forum. Don't worry about the seat modules, nothing you can do about them, when they fail they fail and they are too expensive to just arbitrarily replace. If it happens to you, just put the seat where you like it, unplug the seat module under the seat and charge the battery and you are good to go until you can get it fixed.

Key to happiness with an MB is finding the right mechanic and avoid MB dealers at all costs.
