I haven't been happy since I had my car, which I purchased in 2012 with 45, 0000 miles at the time of purchase. I complained about so many things every other month I was going to get it checked. When you hit a bump you can here something loose underneath the front end of course I seemed like the only crazy one hearing the noise. Then when I took it back again I was told the sway bar arms need to be replaced when this was a problem when I first purchased the car they just ignored now my warranty is expired . The steering lock was one issue and I was told through the dealership that there was not a recall on my car. Until I contacted you guys I was told that there was a recall. Now when I drive the car at a certain speed it starts wining and slows down to 60 mph with the gas pedal to the floor I am furious because I was traveling on the interstate 4 different times going out of town and this happened. Someone could have ran into the back of me. I changed out the air filter thinking that may have been the problem but no it continued. Also sometimes the car wouldn't start I was told by Nissan I needed a new battery and I had it checked by someone else they said the battery was fine. The passenger sensor light stays on when an adult is sitting there. Now my sister 2013 Nissan Altima transmission is gone and she only had the car almost two years and we were complaining about the issue with the car going a certain speed and making noise. I went to Nissan and they told me my car can be put on the machine, but I would have to pay to have it checked. Too many people having the same problems with these cars.
