At 26k miles a very loud, grumbling, droning noise started coming from the vehicle's transmission. Apparent at 25mph. The cvt transaxle assembly was replaced by the dealer but the noise is still present . It is worse than before. The noise inside the passenger cabin is unbearable,deafening specially at higher speeds. It feels like the vehicle is stuck in low gear. It is very difficult to hear other cars outside as I have to increase the volume of my radio and open windows to try to mask the noise. Similar complaints have been filed with other Nissan models using the same type of transaxle.
