 Manufacturer radiator & Transmission Defect. And they are very aware of the issue but will not make it apart of their recall. Theyve extended the warranty coverage to 80K miles. But the issue doesnt start until 80,100 Miles! I own a 2007 Nissan Pathfinder. I was driving 40 MPH & attempting to accelerate but the vehicle wouldnt respond. I took the vehicle in to the dealership for a diagnostic check($100 later) only to tell me that code P0717 is the issue. Which is a cross contamination of fluids from the radiator in to the transmission and both would need replacing. But since my vehicle was over the 80K (uninformed warranty), I would have to pay $6,600! I Won't Stop Until They Do Right!!!
