NHTSA complaint #10983631, filed 2017-05, 11,700 miles2007: “Multiple instances of my car accelerating while in a lower RPM such as at a stop light, drive thru window and parking lots. Especially increased instances when the air conditioning is running. This also causes the car to die completely in some cases. I have to try to pull over somewhere in order to put the car in park and restart it. This issue with the acceleration is increasing in frequency lately. I can count on it to happen every single time I have the air conditioner running and sometimes when it is not. Problem has occurred hundreds of times. It is very dangerous! …”
