While driving the car stalls and you have no steering power or brakes to stop. I was able to coast to get out of the way of oncoming traffic. Restart car again and as I was braking for a stop light the car stopped again. To keep from rear ending another vehicle I had to switch lane and pull off of road. No warning lights came on the car just stopped. The car would start again as if everything is okay, but stall as you slow or come to a stop at a stop light. There is a total of 13 complaints on "Car Complaints.com" for this same issue. Below are some of the complaints on this website: "Driving the car in town at slow speeds, usually around 15-25 miles an hour, with rpms at about 1250. First noticed an issue with extremely jerky driving, but added gas and the problem went away, and I thought it was a one time thing. About a week later, it happened again. Then, a few days later, the car shut off as I was driving through a parking lot. I set up an appointment with the dealership for a week later. In that week, the car died while driving through town twice, and also as I was driving into work once. It is the smoothest shutoff I have ever experienced, only the engine dies, and it starts right up once I stop and put it in park. I don't even notice the engine turn off until I try to press the gas." "The car died 4 times, the engine completely shut off. It would throttle by itself at lights or in the drive thru.I could not drive up until no one was in front of me because the car would hesitate then jerk forward. Almost got hit from behind making a right turn because the car would not accelerate with oncoming traffic approaching from behind." "Were on a very busy street and the car just died. Very hot outside, people backed up behind us. Could start the car, but when lift off the break, it would die again. Police helped us push it off the busy road into a parking lot. Our concerns - this is a new car and a part goes bad? One that makes the car quit? What if it had happen
