Transmission; I have had to change the cvt transmission on my Nissan Sentra twice in the space of a year. Before the last change I suffered a transmission leak that entailed me adding fluid when a whining noise starts. Steering; power steering is hard and does not move with ease unlike other cars I have driven. Speedometer; speed is inaccurate. I got speeding tickets because my speedometer did not accurately depict my speed. It was wrong and off by ~5 mph when speed started to exceed 20mph.
