I was driving through a parking lot and was pulling into a space to park. I did not have my foot on the accelerator, as I was just easing to a stop. The engine surged and my car lunged forward, almost hitting the vehicle parked in front of me. This has happened multiple times since, at one time almost hitting a pedestrian. I have to keep my foot on the break constantly and hope I can get the car stopped before someone or something is hit, and pray I don't have to use the accelerator at the low levels of speed.

Since my vehicle was new I have complained to the dealership, and online, that the optional brake and accelerator pedal height adjustment rocker switch is wired improperly. That is, wired in reverse. The mounted switch clearly depicts a foot over a pedal in the center with an arrow pointing 'up' at the top of the switch and an arrow pointing 'down' at the bottom of the switch. This controls the height adjustment of both pedals from the floor and is designed to place the pedals within reach of the operator. On several occasions members of my family have depressed this switch while in motion pushing the top portion of the rocker switch assuming the pedals would rise 'up' as indicated by the arrows on the switch. Wrong!! pressing the switch in the upward position 'lowers' the pedals to the floor, while pressing the lower portion of the switch, with the arrow pointing 'down', actually raises the pedals up, closer to the operator. After pressing the switch several times in the up position and believing the pedals were at their maximum height, several of the drivers in the house whom have short legs, were immediately panicked and desperately began trying to compensate by readjusting the seat to be within reach of the brake! a scary and dangerous condition while the vehicle is in motion! if Ford refuses to simply reverse the operation of the switch, maybe a safety interlock could be devised to prevent operation while the vehicle is in gear.

For several months car has been lunging forward without my foot on the gas. A couple weeks ago while pulling into my driving way it lunged and the car ran into my concrete steps causing 3,500 worth of damage. This is very dangerous and could have been one of my daughters. I really hope you take this seriously because once lives are lost you can't get them back. I just want Ford to fess up and to take responsibility for this problem, so I may get it fixed and not kill or injure anyone.

Some months ago, my car started to oscillate in ralenti from 700 to below 500 RPM, when braking even stops. Some times decelerate suddenly, frequently slow response when accelerate, etc. Ford local dealer told me this is a regular problem with this throttle body on this engine models, and I have to replace it. I am aware this is a common issue on 3.0L V6 engines due to I have a friend with a montego 2005 with same problems. So far, no Ford company recall was advised. I do not agree into replace this part, should be Ford responsibility.

At a stoplight with the brake on the engine revved up and the car jumped forward about 20 feet before I could stop it. At the next light the same thing happened. At my final destination approximately 2 miles away my son (who was with me the whole time = I was taking him back to college) told me to let the car run to see if it would do it again. With the car in drive and my foot on the brake (hard) it revved up 2 more times in less than 2 minutes to at least 1500 RPM and was very difficult to hold back. I took it in to the dealer the next day and they replaced the throttle body at a cost of $800. After calling Ford and reporting the situation they refused to document this or make a case number until I told them I knew there was a technical bulletin on this according to the dealer. They gave me a case number [xxx] but were rude to me and could not answer if the replacement part addressed the issue and has been fixed. I do not know if it will happen in the next mile, next 100,000 miles, or never again if they will not say if replacement parts have corrected a problem. If a car or pedestrian were in front of me when this happened I would have had an accident without doubt. This car has a safety problem and the incident happened on Nov. 27, 2011.

Ford Five hundred started lurching or lunging when placed in gear. From a parked position.. the car lurched back into the wall of the carport crushing the back bumper. On another occasion the car lurched when the door was open and knocked into the carport post. Very dangerous.

Car will "jump" when shifting into drive or reverse gears!! sometimes the car wont immediately accelerate when applying gas. Was told my multiple mechanics that I was the throttle body control causing this but Ford wont do anything about this!!

In November of 2010 my 2007 Ford 500 began to "leap" foward or backward after shifting from park to reverse or drive. This action has continued for the following months. It seems to be happening more and more often. In may of 2011 it "lunged" when I was backing out of my driveway causing damage to both my vehicle and my husbands who was parked near me. I took it to the dealership today after it "lunged" in a parking lot last week almost hitting a child walking by. I assumed it was the transmission. However, I am told it's a bad electronic throttle body and is not covered under the powertrain warranty. I am told it will go out sometime, there isn't any way of knowing when but it will go into "fail safe mode". after searching online I see Ford had a recall on this part that included models older then mine. The problem isn't fixed as many Ford owners are experiencing the same problem.
