I used  to love nissannot anymore
 I have  a four door 3.5 liter engine Nissan sedan. I was excited when I first got it because it had low mileage and it seem like a very dependable car. I had the car for a little less than 4 months and had to take it into the dealership because the lights were flickering and the Windows would not go up and down.  the dealership said they could not find anything wrong with it and left it at that. A few months later again  it was a sensor that went bad they had to replace that but the lights were still flickering and again they couldn't find anything wrong with it. we did this for over a year went to the dealership 4 times. I don't know if anybody else has experienced electrical issues with this type of vehicle but I highly recommend that you don't purchase.  it is to the point now that I'm actually scared to drive it because it says no key on a constant basis after changing the batteries out I'm pretty much a regular basis. the doors won't lock even though there automatic lock doors and this makes me nervous with my children in the car and driving.  so if anyone has young children and travels more than 15 miles this car is not for you.
