 We had the same leaking radiator problem like many people with our 2005 Nissan Pathfinder. The vehicle was 2000 km over the extended warranty limit. We would bring the vehicle to Nissan dealership if we were made aware of the defect sooner. We asked Nissan for assistance. After many phone calls, emails, time spent collect past maintenance record requested by Nissan Canada and months of waiting, we finally got a reply. Below is my response to their reply.  "Thank you [Nissan Customer Service rep] for passing the news that Nissan would not do anything for our loss and their defective automobile, and for wasting our time. I can assure you we will spread our words about the quality of Nissan vehicle, so less people will experience what we have experienced. I am happy to report that after this incident we have traded in our Nissan for a Toyota which we have been very happy with, and my dad has sold his Nissan for a Lexus. Even though the resale Nissan worths less than other vehicle of similar type and age, it's wonderful to got rid of our headache and future headaches. I will look forward to the day Nissan disappear from this world. Best of luck to all of you working for Nissan."  We traded in the Nissan after replaced the radiator. Transmission was still working at the time, but we didn't want to take a chance of keeping a time bomb. The problem is well known among dealships of other car makers, so we got only $8000 for the trade in, but this is better than having to pay $5000 later on repairs. We had so many problems with this vehicle since we purchased it new from a dealership - noises, signal problem, gauge problem, etc. - and spent a lot of money fixing them including getting scammed by dealership (asked to pay for an item under warranty). What we experienced with Nissan is bad vehicle, bad service and ignorance.  This is our one time experience with Nissan. Lesson learnt.
