Common problems with contemporary Nissan vehicles include shuddering or vibration in vehicles fitted with continuously-variable transmission and radiator leaks in some SUV models, including the Nissan Xterra and Pathfinder. The Nissan Altima sedan has the most reported problems as of 2015 according to car repair statistics site CarComplaints.com, with excessive oil consumption the most commonly reported issue according to Altima owners.
Problems with the CVT transmission on Nissan vehicles often manifest as a jerking sensation during driving or a feeling that the vehicle is stuck in a particular gear, even though CVT transmissions do not use fixed gear ratios. The 2013 Nissan Altima is most affected by these issues according to owners, though other models using CVTs such as the Pathfinder SUV are also affected. Most owners are only able to fix this issue by fully replacing the car's transmission.
Coolant leaks in Nissan SUVs are most common among vehicles built in the early years of the 21st century. Nissan Pathfinders and Xterras built from 2005 to 2007 are particularly susceptible to this issue. In addition to overheating and other issues common to coolant leaks, these Nissan vehicles also tend to leak coolant into their transmissions, eventually causing complete failure of the transmission.
