 I leased a Q50S AWD Hybrid in Nov 2013. The first couple of months I had problems with the Infiniti Connection technology that even the dealership couldn't figure out how to fix. Since then it has been a very pleasant experience. The recent addition of the inTouch apps is nice. The handling and cornering is the same if not better than BMW 335. In Sport mode the acceleration is awesome and the paddle shifters are very responsive. When accelerating from low speed in standard or eco mode the transmission appears confused which gear to shift to first and sometimes fails to respond properly to the driver's foot on the gas pedal.
