The Model S was like this, too. My Model S had a not-quite-fitting front bumper (still problematic), thoroughly dysfunctional rear seatbelts (seemed to affect all of the first several thousand cars including the demo cars, now fixed), some air leaks (gradually getting fixed at service visits), a 12V battery that needed replacement at least once a year (fixed by firmware upgrade -- the original charging algorithm seems to have been written without any consideration for how lead-acid batteries behave), goo dripping out of the sunroof ("fixed" by putting silicone sealant over the goo source), windshield sprayers that are almost impossible to align correctly (design error, presumably still affects current production), and probably several more problems that I've forgotten about.
