On July 25, 2013 the car made a skipping sound when I turned it on and a few days prior it would make a rolling action when stopped. On July 26, 2013 I was in route and after being on the road for 7 minutes at a stop light the vehicle would not accelerate when I pressed on the gas pedal. After numerous attempts it started driving however it would not go past 15 miles making a grinding sound/noise. I was able to get it to the closest mechanic. The mechanic informed me that the a/c coolant had gone into the transmission requiring it to be flushed however not guaranteeing that it will work. I called Nissan on July 26 2013 and was informed that my warranty had expired and that they would not assist in repairing the transmission. At this time, the problem is trying to be fixed and expected to be significantly costly.
