Loud Engine Noise Problems of Ford Freestyle

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.

While maneuvering my vehicle in a small space (forward, reverse, turning the wheel) the car began to surge and lunge (has occurred before, but mostly in reverse. ) there was loud whining when I turned the steering wheel (that began recently and is almost constant. ) the engine began to rev loudly, the car trying to lunge even with the brake applied. I reversed the car several feet from the road for fear it would lunge into traffic. The engine light (1st time ever) and the wrench symbol came on. Car went into limp mode, would not accelerate or exceed 30mph. (4th or 5th time this has happened in the one year I've owned the car. ) diagnostic codes given by autozone on 9/19/p2106 (throttle actuator control system) & p061b (internal control module torque calculation performance error. ) upon restart, engine light off. Dealer was contacted, and on 9/26/12 I drove the car to repair shop. They said Smart junction box melted, must replace (electronic chassis control module )before doing repairs to the throttle body, cvt and suddenly non-working a/c (was working prior). No repairs have been made to the vehicle as the dealership (not Ford) refuses to honor the 36,000ml warranty with car. Recent problems prior to 9/26/12:*highway driving (55+mph/sometimes using cruise) car revs high rpms/will not accelerate at all/resumes later*sputters/stalls/loses power when slowing/stopping (it does restart) instrument panel brightens/dims*power locks malfunctioning (unlock function works with fob only) often while driving car locks/unlocks continuously/car randomly unlocks after being parked/turned off player not working/displayed error code/2 month later working again*security system function inconsistent/disables randomly*gears not engaging right away, then a loud noise and car surges/lunges into drive/reverse* lunging (mostly reverse) and surge/lunge when in drive/brake applied.
