Right after I bought this car, I would find it running, doors lock. This has happened several times. Now its losing power and jerking like its running out of gas yet I have a 1/2- full tank. Even tried high octane gas. When it starts to lose power, the back end starts to jerk or bounce. I have had the dash lights go out..it fried my phone when I plugged in to charge. This has been going on for a year. The dealership tells me there is nothing wrong with the car. I am afraid to drive it. They told me to either buy a new one or go rent a car. I can't even keep it in the garage for fear it will start in the middle of the night and we will have a carbon monoxide problem. Nissan has not helped, I won't sell it because I would feel awful if it killed someone.. So I am stuck with a car that Nissan says is fine. Yet the GM of the dealership said he would not let his wife drive it for a week.
