2013 Nissan Altima 2.5 S 4dr Sedan (2.5L 4cyl CVT)
My wife and I have owned and driven a 2009 Rogue, 2009 Altima, and a 2012 Rogue with no issues or problems with CVT or road noise until I traded my 2009 for the 2013 Altima.
When accelerating slowly from a dead stop, a deep rumbling, vibration noise starts at about 20 mph, briefly stops as you reach 40 mph, then starts again.
After 40, the rumbling continues and then the road/tire noise kicks in, which is much louder with this model. I have had the vehicle checked by my Nissan dealer several times, but the problem has not been resolved.
Love the interior and exterior redesign, the new seats, standard features like bluetooth, driver's power seat
My 2013 Altima has the same rattling/rumbling on acceleration, but if you gun it, the noisy 4cyl covers up the noise of the transmission! ;-) Overall not too impressed with this car, the only thing it has going for it is the looks
