What I come to realize (too late) is that incorporating a falcon wing door design on the Model X kind of works against the general structural integrity. It isn't as solid as a normal 4-door vehicle by having those huge gaps for the FWD in the middle of the car. This leads to all sorts of creaks and noises.10K miles in and the car is a rattle box. It feels like my first Toyota 280zx with 100k miles the way it rattles. Like yourself, when I took into service, they said that this is all normal and expected. My 2 year old model 3 drives smoother and quieter than this car.
