The vehicle has unintended acceleration issues. There was an investigation by the nhsta but nothing came of it. The car still accelerates on its own when I pull into parking spaces or leaving parking spaces. I have to keep my foot on or by the brake pedal as to not hit other cars or people. Having the air conditioning on seems to worsen this problem substantially. It is completely random and I know I'm not the only person that has experienced this issue. Please reopen your investigation and make sure you have both the AC on and off. It's mainly when it is on, but still completely random. I don't know how people and property haven't been injured or damaged as a direct result of this well known issue.

While pulling into a parking space and my foot off the accelerator, the car will suddenly surge forward. It seems to happen more frequently when the weather is hot. While shopping today in 90+ temperatures today, the car accelerated on more than three occasions as I pulled into parking spaces. The car has accelerated on at least two occasions when I have stopped for pedestrians. Fortunately, I had my foot on the brake. Today, I came very close to crashing through my garage cabinets when the engine surged as I pulled into the garage and was inching forward to clear the garage door.

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.

My 2007 ford five hundred sel fwd with the 3.0 v-6 (81,421 miles) and 6 speed automatic transmission will intermittently surge forward or backwards without gas pedal application when idling in gear. It is as if I floored in a jackrabbit start. It does not do this every time that the car goes to idle in drive or reverse (for example, if I am in traffic at a stoplight) but it will do this at least once every time I drive. I have had to keep my right foot firmly on the brake pedal while backing or in a parking lot to keep the car from hitting pedestrians, other cars, sign poles in parking lots and my carport's wall. It will suddenly rev up when in either drive or reverse without my foot on the gas pedal and try to move in an uncontrolled manner. It may only do it once or it may do it three or four times in just as many seconds. I was unaware of this problem and nearly hit another car the first time this happened. There was no warning. No check engine light activated. My car is equipped with a tachometer, I have seen it jump as high as 2000 RPM from a 750 RPM idle and then fall right back to 750. The fact that I have not hit anyone yet is proof that this is not a pedal misapplication error, but my concern is that an inexperienced driver or someone who is unaware of this defect will be surprised by it and kill or injure themselves or someone else. This is the first time I have ever owned a vehicle with such a problem I took my car to my local ford dealer and was told that the problem is a defective throttle body which is being replaced tomorrow. I researched this problem on the internet and have found reports that the replacement part is no better than the original. The fact that a defective part can cause a vehicle to act in such a dangerous manner is symptomatic of a factory defect and should be acted upon by the federal safety agency as soon as possible.
