The Nissan Pathfinder is an SUV now a crossover SUV manufactured by Nissan Motors since 1986, derived from Nissan's compact pickup truck platform. The Pathfinder is slotted in size between the Murano and Armada or Patrol, but in price between the Xterra and Murano. The Pathfinder's traditional Japanese competitor is the Toyota 4Runner. At the 2004 North American International Auto Show, Nissan unveiled a completely redesigned Pathfinder for the 2005 model year. The new R51 Pathfinder uses the Nissan F-Alpha platform, thus returning to a body on frame construction. It is powered by a 4.0 L V6 engine VQ40DE (266 hp (198 kW), 288 lb·ft (390 N·m)) or a 2.5 L YD25DDTi (174 hp (130 kW), 297 lb·ft (403 N·m)) Turbo Diesel. In late 2003, a full-size SUV, the Pathfinder Armada, debuted. Although they share a common name, they have little similarity and use different platforms. The "Pathfinder" prefix was dropped for 2005, leaving just the name "Armada". The Pathfinder is sold as the Terrano in many markets outside of North America. In 2005, when the redesigned Pathfinder was released the Pathfinder name became international as it sold worldwide. These were the first to be sold in the UK. The 2005 model introduced a third row of seats to the Pathfinder line for the first time. The 2005-2010 models have been subject to a class action lawsuit because of an issue with cracks in the radiator that allow coolant to leak into the transmission causing permanent damage that requires transmission and radiator replacement. 2008 facelift (US and Middle East) The facelifted 2008 Nissan Pathfinder debuted at the 2007 Chicago Auto Show. Some of the badge positions on the rear liftgate were tweaked some, and this version also received the Titan's 317 horsepower 5.6 liter V8 engine.
