We were driving on the interstate at about 70 mph and were unable to accelerate. Accelerator peddle all the way to the floor and the most we could go was 45 mph. Had the car towed to a Nissan dealership and found out it was the shift select assembly that had broken/malfunctioned and the car had gone in to failure mode. There was not warning light at all and this could have been very dangerous on the interstate. First I feel that this part of the car should never have broken in a 2-year old car and I have to wonder if there is a defect in the part for this model year of the Altima. Second, if and when this piece does break or malfunction, there should be some sort of warning light on the dash to make the driver aware and pull over. Nissan is aware of my concerns as I have shared them with their Consumer Affairs department.

On Monday night at 12:00am I was driving from California to las vegas Nevada. I was going 75 miles an hour when the car started to loose speed. The excel-orator would not move and had locked.the car speed had dropped to 40mph and would not move. There was a semi in front of me and two other vehicles to the side of me. I almost got into a big accident. I was able to pull over to the side. Terrified, I began to panic so I shut the car off. I drove the next 60 miles to vegas going 30mph the car would not go to a higher speed. When I took the car to the dealer they said it was a safety feature. I do not understand how a safety feature would deliberately jeopardize the safety of the driver. It is driving on the highway for fear that this may happen again.

Driving long distances my car overheats, looses power going from 70 mph down to 40 mph in high speed traffic. I am forced to get off the highway and let it reset itself. It has always made a whining noise during acceleration, and the brakes have squeaked from day one. I have complained to Nissan several times and am always been given lame excuses. Now that my warranty is up they have a solution to my problems. New transmission or overheat converter to the tune of $1600. How convenient they have a solution not that my car is out of warranty!! they refuse to help me or fix my car unless I fork over the money. My car has had problems since I purchased it and there was never any resolve. I purchased an extended warranty as I do a lot of driving. My car was out of warranty 2,000 miles when they miraculously found a cause and solution for my problem.

I had pulled into a parking lot at a local gym, as I placed the car in park, the vehicle continued to stay in drive and surged forward into the building. Once the vehicle hit the building, I once again tried to place the car in park, and it once again surged forward and hit the building. The only way I could stop the car was to hit the power button to turn the car off. Once the officer arrived on scene, he asked me to place the car in neutral so that he could move the car off the curb, however, the car continued to move forward. As a result the car was once again powered down to avoid any further incident.

The pedals are positioned too close together. My husband complained of this a few weeks ago when he drove my car because his shoe got caught on the brake pedal as he was lifting his foot off the gas pedal. Then, yesterday, the same thing happened to me. I nearly drove my car through the front of the daycare where I was dropping off my son. I am now aware of how extra-cautious I have to be when driving my car so this doesn't happen again. This has never happened to me with any other car. I've been driving for 25 years!

The contact owns a 2012 Nissan Altima. The contact stated that the brake and accelerator pedal were positioned too close together. As a result, the contact inadvertantly depressed both pedals simultaneously. Neither the dealer nor the manufacturer were notified of the failure. The vehicle was not repaired. The failure mileage was 5 and the current mileage was 12,000. The VIN was unavailable.
