I was at a red light and when the light turned and I put on the gas my car stalled. I could not shut off the car, it has a push button engine. The motor was off but on the dashboard it said the car was on and all of the electrical systems were still running (heat, radio, lights, etc). When I pushed the engine button, the car would not turn off. The parking break turned on by itself. I could not push my car to the side of the road. I was in the middle of traffic. I had to call for the police and for a tow truck. We still could not get the car to turn off (the motor was not on but the car’s electrical system was still on). We could not disengage the parking break. Finally the tow truck operator slammed the break pedal down and he was able to turn off the car. The car then started. We still towed it to the Jeep Dealership. The could not find anything wrong with the car. Approximately two weeks earlier, the same thing happened at a red light but at that time, after I waited for 10minutes I was able to get the car to turn off then on. My car has two new batteries (put in one year ago), new front breaks, new tires. The day this happened, I had actually just left Jeep from getting my oil changed. they said it was not related to that.
