My car will try to surge forward while at a stop with my foot on the brakes. It will happen while driving, in parked position, and while no gas or brake pedal is pressed. This happened in a pick up line and I could have hit a child if I hadn't hadn't my foot in the brake and done all I could to not move forward. Sometimes I'm in reverse and this happens and it's like I put my foot down hard on the gas. There seems to be a connection to the ac unit, because when that is on it is making a loud sound. I went to carmax 3 years ago (in 2015) with this issue and they replaced the throttle body. Now they are saying it needs to be replaced again. There is clearly an ongoing issue with this part in the car and it is a major safety concern. Sometimes after the surge, my car will �die�. This happened in the middle of 6 lanes of traffic while stationary at a red light. When it turned green, I couldn't go because my car had just surged and died with my foot on the brake pedal.
The contact owns a 2006 Ford Freestyle. While the gear shifter stick was placed in reverse, the rpms rapidly increased with a loud noise. The vehicle independently lunged backwards without the accelerator pedal being depressed. The contact immediately depressed the brake pedal to stop the vehicle. As a result, the vehicle stalled and the check engine and wrench warning lights illuminated. The vehicle was able to restart. The failure recurred intermittently. The vehicle was taken to an independent mechanic where it was diagnosed, but the cause of the failure was not found. The vehicle was not repaired. The manufacturer was made aware of the failures. The failure mileage was 44,000.
