Issue: unintended acceleration conditions: 2pm/clear/parking lot while making u-turn to the right, brakes did not respond. Stepped again on brakes, more firmly, but did not slow car which continued to roll slowly forward about 7 MPH. Suddenly, loud revving, car continued forward roll. Immediately, added left foot to brake, pressing with full weight. No response. About 2-3 second after revving/hard braking, the car opened full throttle and hurtled forward about 1-1/2 to 2 car lengths; slammed into wall. Airbag did not deploy my car had only 25290 miles (only about two years of normal usage) at the time the system failed. My left knee sustained small gash from the underside of the steering column when I was slammed back after impact threw me forward, forehead knocked the upper steering wheel. Note: about 1 month prior to accident, the audio controls on my steering wheel honked the horn instead. The next day, they were ok. The same thing happened when tested at the collision center after accident; it's on tape. The rep at the collision center was informed of the switch problem from the start. When I them tested days later, the audio controls worked properly. Also, an indicator on the dash went from showing the mpg with a bar as I accelerated or slowed, then switched to a digital report of 18 mpg/city. It kept shifting between these indicators without my interference. Finally, the airbag failed to deploy although impact clearly exceeded 15 MPH. I believe there was a severe failure of the electrical system; the CVT system with its sensors, etc. Is dependent on it. My account parallels reports I have uncovered about sudden acceleration. I noted that often an event was precipitated by a slowing, and a turn. When I recently talked to a nissan tech about the switches, airbag, indicator failures, he mentioned pinched harness could be a possibility.

Tl* the contact owns a 2009 nissan altima. While driving approximately 5 MPH, the contact attempted to park when the vehicle suddenly accelerated while the brake pedal was depressed. The vehicle went over a curb and crashed into a row of bushes. The vehicle sustained body damage yet there were no injuries. The police reported to the scene and a report was filed. The vehicle was driven to the dealer where the technicians were unable to diagnose a failure. The vehicle was not repaired. The approximate failure mileage was 39,000.
Vehicle transmission failed. From a stand still at a stop light, the vehicle shook and then jumped forward 2 feet as if being rear ended from behind. When the light turned green, I stepped on the gas and the vehicle started to accelerate. Then the vehicle made grinding noises, hesitated, shook, and completely lost power to the wheels. The first incident (jumping 2 feet) almost caused me to hit the vehicle in front of me. The second incident almost cause the vehicle behind me to rear end me because we were accelerating to merge onto a main road, and my vehicle all of a sudden stopped dead in the middle of the road, but with the engine still running.
When the brake pedal of my 09 altima 2.5s sedan is pressed, the car slows down as it should and then all of a sudden accelerates until the brake pedal is pressed harder when it comes to a complete stop. This does not happen always and the amount of sudden acceleration varies from time to time. Today around 12:30pm, I tried to stop the car by pressing the brakes and it suddenly accelerated and hit another car. The police arrived, listened to what happened, and reported the accident as my fault. When I told her (officer dick) about the brake malfunction, she made fun of me saying -- "are you trying to pull off a toyota here?" I find the brakes of my car very unpredictable and that was the reason for today's crash. Hope the federal safety agency will take this report seriously and do the needful.
Bought car new in 2009. It has surged forward out of control three times at slow or parking since I had it.

Leased a new 2009 nissan altima on september 5, 2009 and on september 13, 2009 while my wife was pulling into a parking space at a local supermarket our car suddenly accelerated and crashed into the wall of the market. She was burnt on an arm because of the air bag deploying and suffered from a blood clot, both of which have healed.
