Bought my Altima new 4.5 years ago. I have only driven 33,000 miles in that time, but haven't had any problems. Driving it is a blast! The 3.5 engine wants to run all day. It has a lot of power on tap whenever you want it. The brakes are great as well. Big discs at all 4 wheels stop quickly and smoothly! Any complaints I have are minor, but here they are. Torque steer can startle you, for sure. If you go to pass someone quickly better hang on to the wheel tight, cause it will pull. The cvt is mushy. I just leave it in sport mode. This little car begs to go fast, so bad m.p.g. The ride is a tad harsh at times. The suspension is not compliant at all! The steering feels fake but the car tracks straight and true. The base stereo is a little weak sounding. Again, minor complaint. I drive from Owensboro, Ky. to Lexington, Ky. [180 miles one way] quite a bit, and the trip is quick and pleasant. I have enjoyed owning my Altima. If you can find one with a 6 cyl. buy it!
