Purchased used Nissan Altima 3. 5 v6 engine vehicle with 18k miles on 10/29/11. On a couple times before when slowing down to brake the car felt as if I was no longer in control of it and accelerated. However on 11/14/2011, I slowed down to stop at a busy intersection. I applied the brake as usual slowly to come to a complete stop and the engine began to rev up and made an increasingly loud noise. The vehicle felt as though it wanted to move forward in to oncoming traffic. The harder I pressed the brake the more it revved up. My foot was not on the accelerator at any point. After the light turned green, it lurched forward and I immediately drove to the dealership where car was purchased less than a block away. The service man placed it on the computer and all kinds of red lights flickered. He said something is wrong but we don't no what. They seemed to be at a lost. Finally I was told they needed to drive it to try to recreate the occurrence. Car is still at the dealership after 3 days. They have given me a car to drive. I am so disappointed in this purchase. Certified vehicle with a wrap around service warranty will hopefully save us expensive repair bills. In any case I don't want to drive it anymore because I don't feel safe at all. I want to trade it and request a buy back if this matter is not resolved. Having the mechanic tell me there is nothing wrong is just not acceptable because we could have lost our lives. Our 11 year old son was in the car with me and was very frightened. No car is worth the risk of driving dangerously.
