When you take delivery, DON'T let them shove the Ipad in your face and ask you to press the "Accept delivery" button before you have thoroughly inspected the car. Off the top of my head, here are things you should check (some were bad on my car delivered in June, all but one fixed now)
1. use your cars charge cable - plug it into a 120V outlet and push its button - does the charge port door open? If not, on the first try, make them replace the charge port as you have one of the gluey ones that stick closed, and you don't want that!
2. open the frunk - check all the plastic panels - are they in place? flush? snapped in good?
3. drive the car - get on the highway and go 70 mph - any noises? a thumping noise might mean the stoppers on the hatchback lid need adjustment
4. run your fingers over the rubber gaskets on each door - are they fixed in place? one of mine hangs loose and moves a couple of inches out of place if you rub it with your hand - still don't have this fixed
5. are all your floor mats in place? mine weren't and the plastic part that holds them down (its a round thing that screws into the carpet) was laying on the floorboard.
6. while you're driving it, go someplace and make a hard left u-turn - does anything make any noise in the dash - there have been cars that had something loose in the dash they had to remove
7. are there any squeeks in the dash, particularly above the 17 in touchscreen? they can put a felt strip in that will silence this
My car did the same as yours - got stuck after production in the quality check - and as it turned out for good reason. You might also go over the paint very closely and note any big defects.
Either go over the car with a fine tooth comb before "Accepting delivery" on the IPad, or forever hold your peace!!!
