I just got my new Model S85 on 9/11/14 (two weeks late due to the factory shut down) and there still seem to be issues with the quality control. I drove the car 18 miles and it started sounding like I had run over a 10-gallon plastic jug and it was bouncing under the car. I pulled off the freeway at the next exit and looked under the car and saw the whole plastic panel under the car at the back was hanging down like a scoop. I called Roadside assistance and they had me towed back to the dealership. They informed me at the dealership that the bolts were not tightened at the factory and were not checked prior to delivery. They replaced the cover and got me on my way in about 15 minutes (gave me a coffee mug & water bottle and promised a free detail), but it took another 3 hours before I got home. For the past two mornings (days 3 and 4 with the car), I have had to reboot the computer system in order to get the display (and the car) to function. The car also seems not to connect to my iPhone 5s and I have had to remove it and re-install it twice now. I am hoping these hiccups get better.
