We have had the car for about 3 years now, the car surges a little when it is put into gear (drive, reverse), more recently the car has begun to surge and or lunge sometimes dangerously when the car is stopped. (not all the time, randomly) I have researched this issue on the internet and I have discovered that its not covered under any Ford warranty. I haven't found a definitive solution for this issue either.

2007 Ford Five hundred, in July/August of 2010, at around 70,000 miles, began to have irregular acceleration and would lunge forward while braking or at a complete stop with brake pedal pushed all the way to the floor board. Had the dealership run the diagnosis, was told it was the throttle body and it needed replacing. Had the repair work done at the dealership on August 12, 2010. On August 30, 2011, took my car back to the dealership after having the same problem repeat, only more aggressive from the first incident just two days ago, even as I pulled into the dealerships service parking space. Was told they will have to diagnosis the problem again, nothing is under warranty. I am just over the 12 months, and at about 30,000 miles after the repair was done last year. Warranty or not, this repair should have lasted the life of the car or at least another 70,000 miles, not 30,000. I didn't have the dealership keep the old throttle body. The warranty company had told me last year that the part, the throttle body was on back order, but the dealership had no problem getting the part, supposedly. I'm concerned the part wasn't replaced, but I have no evidence of such. I have noticed each time, the problem is worse after I have the car idling for a time before putting in gear, reverse or drive. Repair order detail - internal copy reads "inspected and tested vehicle for accelerating without a command. Ran self test to retrieve pass codes. Installed monitor and fuel pressure gauge to road test. Testing resulted finding the throttle motor binding intermediately. The throttle body was removed to inspect and replace. The processor was reprogrammed and retested to verify operation." I had to pay for fuel injection service, replace fuel filter, which I was told I needed to have done with the repair/replacement of the throttle body.

I have a 2007 Ford 500 that started surging forward and backward. I took the car and my extended warranty to a Ford dealership only to learn that the dealer that I bought the car from had back-dated my warranty to the time the car was put in service. (I had purchased the car as a "program" car.) my warranty had run out according to them 6 days before I took it to the dealership. I wrote a letter to Ford and they refused to honor it even though I thought I had purchased a 5 year, 100,000 mile warranty. The car is still surging forward and backward and Ford refuses to do anything. I will never purchase another Ford product. I have owned Lincoln and Ford all of my life and I will never get another one. I cannot believe Ford refuses to take care of their customers. This is obviously a safety hazard that Ford needs to repair. Seeing all of the complaints that people have sent in, Ford knows that they are in the wrong and still they do nothing.

The vehicle lunges forward on its own power. The gas pedal is not pressed and it is not obstructed by any foreign or manufactured object. This has resulted in many near crashes.

My husband and I purchased a 2007 Ford Five hundred last September. I am reluctant to call the dealer about the problem we are having with the Five hundred, because we are not on good terms. The reason for that is they think we traded our 2000 Mitsubishi in with a bad transmission. That is not true. We never had any tranny problems with our car, and we did not want to trade it in, but because we didn't have a down payment, they said we had to trade it in. It was not our idea to trade the car in, and we knew nothing about the tranny being bad. They took an attitude with us after that happened, and a couple of minor things that needed fixing on the Ford Five hundred, they would not fix. Now we are driving in a dangerous vehicle, and from what I found out, there was complaints made in October of last year about the throttle, and we were never notified. We just started having problems with the car lunging forward, and backwards, and accelerating on its own. We almost had two accidents because of the car surging like this. The car is dangerous, and we have pulled up many complaints about these cars, and people complaining to their dealers, and they had to know about it. They say last October was when complaints were made and dealers were notified, but they never let us know, and the car would have been under warranty then. We should have been notified that there was a problem. Please let me know what you can do. Here is a copy of just one of the complaints I found below.

When backing out of a parking space, car will lunge back a few feet. Just last week, I was backing out of a parking space at a store and it lunged five times before I took it out of reverse and put it into drive. It lunged again forward and then I was able to drive it home. If my foot is not on the brake, the car will continue to lunge unless it is stopped either by braking or hitting something. When in a drive-thru, with foot on the brake, when I release the brake the car will lunge forward. After researching the problem, people have stated it is a problem with the throttle and it could cost $500 + dollars to repair. It is a factory mistake that Ford is not taking responsibility for. I was advised to file a complaint with NHTSA just in case an accident occurs because of this problem. We are taking the car in to see if we can afford the repair on our own next week. If it is the throttle and does cost as much as others have claimed, we will not be able to afford the repair.

Purchased a new Ford Five hundred in 2007. Have kept up with all regular maintenance. After putting about 20,000 miles on the vehicle, I started having a problem with sudden acceleration. I would come to a stop at an intersection, mailbox, or drive-thru and let my foot off the brakes and the car would "jump" -- accelerate on its own. My foot would not even be on the gas pedal. I took it to the Ford dealership and was told that the transmission had to be "reprogrammed". I specifically asked could it be a problem with fuel system and was told no. I had the work completed but the problem persists to this day. I have had several near misses with rear end collisions. Finally as I was entering a parking space, the car accelerated on its own and hit a post in front of the parking space.

I purchased a Ford 500 07 in March of 2010. Prior to the 60,000 mile warranty ending, I took the car back twice for a surging problem going from drive/reverse. The first time the shop could not find a problem. The second time the service mgr. And daughter did a test drive. Right off the bat the car surged. He called me and told me to bring the car back one morning so he could keep it all day. I could not do this at the time, this is my only means of transportation. On 10/2/10 while backing up in the emergency lane on the interstate. My car accelerated on it own, while moving backwards. I hit the brake the accelerator went to the floor. I lifted my foot off the brake it took off again. The RPM hand was going crazy. I had no control. The car went into a spin, I ended up in the ditch while hitting another car. Luckily we are still alive.....updated 08/08/16
