CarComplaints.com Notes: There are no warning signs of the same "radiator leaked and killed my transmission" complaints that have plagued previous model years.

For earlier Pathfinder model years (2005-2008), a defect in the radiator allows engine coolant to leak into the transmission. However this defect doesn't appear to affect Pathfinders from 2009 & later. Nissan did include the 2009-2010 models when they extended their radiator warranty on 2005-2010 Pathfinders to 8 years/80,000 miles in response to the transmission defect.

The contact owns a 2009 Nissan Pathfinder. While driving at approximately 40 mph, there was an abnormal noise coming from the front of the vehicle and the service engine warning indicator illuminated continuously. The vehicle was taken to an independent mechanic where it was diagnosed that there was cross contamination in the radiator. As a result, the transmission and the radiator needed to be replaced. The vehicle was later taken to a dealer where it was confirmed that the radiator failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 101,000. Updated 10/05/16
