Engine ping noise from engine at times really loud noise got worse then more problems happened over time at a stop car was accelerating like if was pressing the brake and the gas at the same time, next car would come to a stop then lost power when accelerating the car would not go more than a few mph this happened a few times and once down hill the car would not go in reverse and almost hit a parked car also almost got in an accident because the car would not clear an intersection, I also got video footage of incident, dealer keeps saying there is nothing wrong and the car is safe even after they saw the video they say the computer shows nothing then a recorder was installed in the car and the car was accelerated by itself the recorder button was pressed and the car was then taken to the dealer the recorder was taken off and the main Nissan company called me and said that the information on the recorder was accidentally erased. I have had many problems with this car since I had it this is my main concern but I have had problems from the windows not rolling down to the airbag light turning on and tail lights not working the dealer is not helping neither Nissan direct and at this point im concerned of my safety and my family's.
