 The variable transmission was a problem from day one.  Very inconsistent when shifting.  RPMs would race at odd times.  Had to have the entire transmission replaced at 40,000 miles.  After it was replaced, it made a rattling noise when first hitting the gas pedal.  Very, very disappointing.  The four cylinder engine was sluggish.  The interior comfort was very good.  I liked the car's interior and the outside was a good looking car.  Very comfortable front seats.  Quality leather.  Plenty of trunk room.  I ended up trading the car in after 18 months of ownership at the mega used car dealer where I purchased it from.  They were very fair on the trade, but I still lost money due to the short time of ownership and the rapid depreciation of the model.  I won't purchase a Nissan again.
