While I was driving I had come to a stop at the stop light. When it turned green I began to make a left turn. Halfway through the turn at a few miles an hour my engine light and traction control lights came on. At the same time the engine began to rev to about 4500 RPM. It died down quickly. I then had no response from the accelerator. Luckily I was able to pull over to the side of the road as I had just entered a town. I turned off the car and attempted to restart it. It would not restart until about 15 minutes later. The shifter became locked in the parking position and even after using the shift release button I was still unable to move the vehicle. Luckily again I had just entered a town but a few miles before that I was on country roads where there was no cell phone signal at all. I would have been out of luck as well as the passenger with me. After an hour and a half of waiting the tow vehicle came and was able to get it home and then once again towed to the dealership I had bought it from. It has now been sitting there for 5 days and have been told repeatedly now that no one understands what is wrong and have had to get a specialist to come in to take a look at it. This is a car that I have only owned for 3 weeks and bought outright with only 44 miles on it. It now has maybe 350.
