Bought my 2.5SL about a month ago and it's my first Nissan after owning Toyotas and Hondas for the past 10 years. I feel the car is attractive (inside and out), smooth to drive, and has nice features such as blind-spot monitor, reads text out loud, back-up camera, Bose speakers, and very comfortable leather seats. Heavy traffic commuting=24 mpg. Two issues have annoyed me: 1) the high-pitched morse-code whine at low speeds resonating from the power-steering pump (that lots of other people also notice), and 2) a buzz from the engine @1500 rpm under light acceleration (also noticed by lots of other owners). Without these problems I'd give the car 5/5 stars, but now feel it only gets 3/5 stars.
Leather seats are very comfortable; Stereo is good; blind-spot monitor is very cool; good gas mileage;
Fix power steering pump that emits high-pitched whine and buzzing at 1500 rpm.
