Shifts rough - Nissan dealership diagnosed as cross contamination of engine coolant, atf, and milky radiator cap. Recommed replacement of transmission, radiator, trans cooler and thermostat. Quoted $6400 to repair. Who has $6400 laying around for car repairs. With only 122,000 miles on car I certainly didn't think I would be needing to purchase another car and have car payments right now. No help from Nissan and we just found out about this problem and that Nissan is well aware of it. They should be covering the problem.

I bought the Pathfinder brand new in 2008. Shortly there after, when I inserted the key into the ignition, it makes no attempt of turning on. It has left me stranded on 7 occasions thus far. When I put the key in and turn it, it does nothing. I brought it in last year and they never found what was wrong with it. The warranty expires in two weeks and I do not want to be left with a problem once the warranty has expired. Luckily it has only left me stranded within 30 miles of home, but I am not looking forward to being stranded far from home. After a good 30-90 minutes, the car will eventually turn on. I have had to get a ride from my parents from the supermarket, had my husband leave work to pick me up from another town, walked to my parent's house because the SUV would not turn on. When I have spoken to the service people where I bought it, they have told me that if they cannot replicate the problem, they cannot fix it. It is very frustrating to insert key and not have car turn on. I am bringing car once again to dealer to see if problem can be resolved. I want the problem resolved prior to the warranty running out.
