 This is my third Infiniti after driving an '04 FX and an '05 G35, which I enjoyed tremendously. I had to have what was marketed as a new and improved FX for '09. I think the new styling is incredible. However, I have never been so unhappy with a vehicle's performance. I'm beside myself - I just threw away $40K+. In slow and go traffic, the shifting is all over the place while it attempts to find the right gear. Unless I'm able to drive aggressively, I find the 7-speed transmission unacceptable. From a stop it performs great. Once at about 22 mph is where I realize issues. Several times, when coming to a stop I thought I got bumped from the rear as the car has lunged - it's just not smooth. :(
