Last summer I had an issue with the butterfly valve on the exhaust system. It was a Saturday, I was on my way to work and the only place that was open and the closest was the Nissan dealership. I took it in there they fixed it, but the repairs were over 1 grand. I don't have that kind of money lying around so I called Nissan corporate to ask if I can have financial assistance. They said because I don't service my car at the dealership they can not finance me and help me with it. The Nissan dealership is out of my way to get it serviced. Second issue started recently and that is when I am driving my car there is not very good acceleration and once I hit 20 mph I start to hear a whining noise. I did some digging in several online forums and those with similar issues have been told its the cvt transmission. Last week I barley went over 73,000 miles on my odometer. I do not have money to replace an entire transmission, nor do I really care to. I will never purchase another Nissan as long as I live. There cooperate customer service sucks as well as there cvt transmissions!!.
