I have an 2012 altima and no problems. If you are under warranty, definitely take advantage of it. I haven't heard of any big issues with Nissan. One thing to keep into consideration is many cars are becoming more computer based, not so much mechanical as older models. Nissan stays on top of issues and works out most kinks, it could just be your car. Every car is made equal, but there are always differences in each and every car.
