 I bought a 2006 Nissan Pathfinder with 50,000 miles on it.In about 2 years the car started shaking and vibrating on the highway.I started researching and found out this is a serious problem with Nissan Pathfinders 2005-2011.The Radiator fluid mixes with the transmission fluid and causes damage and puts i you in danger in the middle of the road.The estimate today from Nissan dealer, $10, 088 and I owe $10, 000 on the car! Do your homework.The frustrating entries about this car are all over the internet, including class action lawsuits!
