I returned my S90 at the end of a two year lease. The self driving was frightening. It often drifted out of the lines then would jerk back into the lane then disable itself without warning. Also, the start/stop (or w/e it's called whereby the engine turns off when you stop) was such a jerky experience and sometimes it would turn off before I even came to a complete stop. The infotainment system was terribly slow and would take almost a minute after starting for it to become responsive. Typing into the nav was especially sluggish and unintuitive. One time the AC crashed (not the HVAC unit, the computer module) and I had to take it in for a software update to fix. The luxury, look and feel, and comfort were fabulous! The drivetrain and tech were trash!
