Fuel tank failure, fuel leak, vapor leak. This due to a failure of the seals on the fuel tank along with the deterioration of the mounting brackets on the fuel pump and fuel sending units.

Wrench indicator light came on and car began to spotter and surge. The next day I took it to the Ford dealership and the wrench light and check engine came on. Car stalled out 2 times on the way to the dealer. Dealer wants $950 to replace throttle body.

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.

Was stopped at a drive-thru window and when I went to pull up to receive my food, the car lurched ahead of the window. I put the car in reverse to pick up my food and it lurched so fast backward that I had no control of it, even with my foot on the brake. This caused a crash into the front of another car. I have never had an accident and I am a careful driver. I received a moving violation and there was damage done to both cars. Enough damage that our insurance company is involved. Ford should do something about these lurch problems before someone is killed. Thank goodness no one was in front of me or they would have been killed, please, Ford, do something about these Ford that have this problem.

Automobile lunged forward without touching gas when air conditioner or heat on. Took car to dealership and they cleaned throttle plate, fuel injection throttle body and reprogrammed powertrain control. Seen online others had this same problem. Car only has 47,000 miles.

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.

- Chuluota, FL, USA

Defective throttle body causing "lunging issues" almost had three accidents, just from the lunging. Once I let off the gas pedal the car would turn off, dealer advised that it due to a defective throttle body that they will replace costing me $900.

Last year I began noticing that this car upon putting in gear trying to exit my garage would surge forward or backward, whatever way I was pointed, abruptly. It does not matter whether I am in reserve or drive. I would have to apply brakes to stop it. Sometimes more than once. This would happen if I was backing out or driving forward. It did not go away and in fact became worse. It finally lunged backward as we were leaving a parking lot and the engine stopped. A wretch symbol came on. We took it to Ford. They replaced throttle body part. Was fine until the last month or so and now is worse. Have approx. 77 K miles on it now. I have scheduled to take it back to Ford. I feel this is dangerous as this surging and lunging could result in someones injury. There is obviously a defect somewhere in this part. I have noticed throughout the internet that are many such complaints of this same problem.

- Daytona Beach, FL, USA

I have been having a problem with my 2007 Ford Five hundred, when putting the car in gear the car will lurch forward or if putting the car in reverse the car will lurch backward. I took the car to the Ford dealer to find out what the problem may be; cause I thought maybe it was a broken motor mount. I was told that it may be in the motor. I'm also having an issue with the rear passenger door sounding like water build up inside the door. I check the web to find out if Ford had a recall on these issues to find that other owners are having similar issues.

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.

When the car was still under the 36 month 36,000 warranty it began lunging forward or backward when you first started to accelerate. Noticeably when first taking out of park either going forward or reverse, or when going through drive up windows. (ie fast-food or bank). Intermittently at first and then more and more until it was doing it every time, and at a greater acceleration. The Ford dealer diagnosed it as the throttle body. They knew right off the bat, it evidently was a common problem. We had to wait over a month for them to finally get one in because they were back-ordered. Evidently lots of people needed them! we were advised not to use our car during this time because of the safety issue. Of course the dealer did not want to provide a rental car even though it was under the new car warranty, but after making complaints to Ford Motor Co for three weeks while the part repeatedly did not come in, we were given a rental until it was finally replaced 11-2009. Now it is doing it again. I called the dealer and they said the new car warranty is up and they will not warranty their repair because it has been over 12 months. The car now has 41,000 miles and this is the second time this problem has occurred. I should have reported it the first time but Ford seemed to be taking responsibility and the way they talked to me I thought there was going to be a safety recall. It is a terrible safety hazard. Now that the new car warranty is up their memories have gotten bad. The local dealer (ken garff Ford) told me they are unaware of this being a problem with the 2007 Five hundred. Which is total bull because they sure were aware of it the first time a year and a half ago. I am really disgusted with my dealership. I am waiting to see what Ford Motor Companies response will be. Either way I felt it was important to let others know of this defect. I wonder how many fender benders have been caused by this. I am afraid a pedestrian could be hit and seriously injured.

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.

Car lunges and surges when coming to a stop and idles erratically sometimes. It started randomly but is now starting to do it every time we drive the car.

- Tampa, FL, USA

Car was jerking on acceleration, was told there were no codes even though the light was flashing it is still doing it only worse the light is on solid now and the car is now out of warranty. It would also jerk when taken out of park or when in traffic sitting idle, once I thought I was rear ended. I took it to the mechanics and they told me this is 'normal' behavior and there was nothing wrong with the car. It will not even stay running now when warm and it dies.

- Dresser, WI, USA

I have a 2007 Ford Five hundred that had less than 60,000 miles when the throttle body began to fail. This causes the car to jerk forward and backward as I am taking my foot off the brake. I have almost hit a pedestrian once and other vehicles on more than one occasion. I took the car to the Ford dealership, was told it was the throttle body and there was not a recall even though this was very prevalent in the Ford freestyles. I was also told it would cost at least $700 to fix. They did clean the throttle body for which I paid $70. That was about 2 months ago and it is jerking again. This is dangerous as I cannot keep my car from jerking no matter how slowly I move my foot from the brake or not completely.

- Titus, AL, USA

I own a Ford 500 2007. The engine seems to rev up with out pressing the gas pedal. If you are at a stop sign and release the brake the car will lunge forward on its own. I spoke to a mechanic about this problem and he has encountered it before with other 500's. he told me its the throttle body. He told me when he orders them they are on back order.

- Raton, NM, USA

The throttle body on our 2007 Ford 500 stuck closed causing engine to stall. The throttle body had to be replaced. Fortunately this happened on a 2 lane road but my wife had just got off a high speed interstate highway. Failure caused rapid deceleration of the vehicle leaving her stranded in the traffic lane. This would probably have resulted in an accident if this would have happened on the interstate. The car has around 37,000 miles on it.

- Masontown, WV, USA

Sudden acceleration in both forward and reverse. Has occurred on four (4) separate occasions. Ford dealer can find no codes, therefore refuses to repair. As with most sudden acceleration problems, I suspect the throttle body is defective. This is a serious safety issue!

- Smyrna, DE, USA

I own a 2007 Ford 500 & have recently been having a issue with surging when I have my car in the park position & put it in drive. Then it started surging when I am in reverse now. I spoke to my local Ford dealership when I had my oil changed & they advised that I had to have a update that cost $81 to fix the problem. They knew exactly all about the problem when I started explaining it to them. It takes about 1 hour to fix the problem. I am going next week to have it done.
