We have about 12,000 miles on it now. After owning two Hyundai`s, I guess I expected more from the Sentra, sinse we paid more for it.
No problems so far. Does not get the mpg advertised, we average 30-32 at best.
My only complaint would be the CVT transmission,
we live where we have a lot of two lane country roads where you may need pass slower traffic offen. I have found it accelerates faster at about 5000 rpm than it does with your foot to the floor.
I find this irritating and if this is normal, I would not own another Nissan if this transmission was the only option.
Normal driving, It seems to work fine.
