I bought this car brand new when it was released in late December 2006, almost 2 years later, I had informed my tech when I would bring my car in for scheduled oil changes that I hear a slight noise coming from under the car and sometimes a vibration, over these next few months and yeas I have been told it was either a bend in my rim, needing new tires, to having exhaust leaks or alignment needed. So I would take it to another shop and they would tell me different or if they confirmed I would get the service done at a licensed mechanic. Over time the noise grew louder and louder and dismissed each time I bought the car in for service. Until recently I figured out that the noise would only be heard and present after highway driving for 45min or more. So I reproduced the conditions before I took the car to the dealer for diagnostics then the advised me that there was sever rust taking place inside the transmission. The the tech preceded to tell me that may have started when my car was in an accident 3 years ago in 2008. I contacted the bodyshop that did the repairs the provided paperwork proving that my transmission was never effected or touched as part of the accident. The transmission is still under warranty, and I even have paperwork from the same Nissan dealership that shows that Nissan did a multipoint inspection where they inspected the transmission and its fluid just 8 months prior and found it to be in good condition n no presence of rust or fluid issues. Nissan is refusing to own up to the malfunctioning of there cvt transmission and cost for replacement.
