I bought a 2012 Nissan Sentra I kept up with all the work for the car so to be sure nothing would go wrong. About a year the car started making noise. I told the service dept. But they did nothing on 07-10-2012 the service dept told me I needed a new transmission the car is only two years old. The car began to run really bad. I had to get another car for fear that this might blow up.
Upon accelerating the car makes a awful clunking noise that is not only heard but felt on the floor under your feet this happens often. The dealer stated this was normal. I pressed the gas pedal while switching lanes and the engine revved up, but the car did not move. It took the transmission several seconds to catch up to the engine.
