The tilt motor on my passenger side 2nd row monopost seat broke, preventing the seat from tilting forward or back. It moves perfectly fine horizontally, though. My Model X 6 seater is in the service center right now. They are ordering me me a whole new seat to replace it, and will do temporary repair in the mean time. The car is only 7 months old. Luckily it drives fine. Anyone else hear of this problem?
