While supposedly "stopped" at a red light, I realized I was rolling forward with the brake depressed. I pressed the brake pedal to the floor and the car stopped. When I accelerated ever so slightly, the car bucked and jolted forward. I slowed to a stopped with barely there brakes, put the car in park and pumped up the brakes, raising the pedal. This seemed to temporarily help, but the pedal went to the floor again the next time attempted to stop. Car is at the dealership now. I am awaiting their call.

I only had my car for about 10 months. I keep my car updated with the maintenance. I drove to las vegas, Nevada Friday afternoon. My car was running great I get to las vegas Nevada I here this loud grinding crinkly noise coming from my engine or transmission. I take it to planet Nissan in las vegas Nevada. They took forever to even take me as a customer. Then they come out and say you are not eligible for a rental and your transmission went out. They proceeded to tell me that I will be responsible for the car as far as picking it up when its fixed. This is the worst experience I had with cars. This is the third time something bad happens to this car and its supposed to be brand new. I bought it with 32 miles on it. Mind you all this was on a trip I took to vegas with my family. My two year old son was drained from this experience having to spend 6 hours at planet Nissan. They even try selling me a another new Sentra.

I was waiting at a red light to make a left turn. Once the light turned green and I stepped on the accelerator, the car started to jerk and lost power. It did not turn completely off but it would not drive. I had to put my hazard lights on to avoid being rear ended by the vehicle directly behind me that was also making a left turn. I owned the car for less than 24 hours at that point. It only had 152 miles on the odometer. The dealership sent a tow. The diagnosis was that the software needed to be updated. I don't understand how Nissan can sell a car that isn't properly programmed" why wasn't the programming checked prior to me driving it off the lot" I will drive it for a few days to see if it happens again.
