2013 Nissan Altima Sedan 2.5 SL 4dr Sedan (2.5L 4cyl CVT)
Used 2013 Altima 2.5SL
 We had one problem with the CVT.  The car was stopped in traffic and then would not move forward. eventually IT MOVBED.  The dealer could not duplicate the problem.  The software for the transmission was reprogramed.  We have not had a problem since.  The navigation seems to not work correctly at times but then is fine.  The auto is a very comfortable highway cruiser which is marred with a little wind noise from the outside driver mirror.
