 I purchased a 2014 Nissan Altima 2.5 SL 4 cy on 8/4/2014. In November I experienced power outage/ shortage in tech system the radio, navigation, LED screen all went out. Everything there is a change in climate or when it gets cold I have these issues, sometimes lasting for hours. I then noticed my car riding ruff as if it wasn't shifting gears properly. Took it to the dealer and the bearings I. The transmission went out had to get a new transmission in May 2015. The dealer replaced free of charge and provided a rental. Now in November I am again experiencing a ruff ride, car smells like gas and a strong smell of burning something has come a loose from the front and side underneath the car. My tech package, LED screen and Navigation has went out again! The side blind spot indicators flash even when there's not a car on the side and in the rain the do not work properly! The interior is not durable at all! Leather is starting to peel. The car does not ride smooth anymore.
