Gasoline Fuel System Problems of Ford Five Hundred - part 2

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!.

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. 00 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.

I have a 06' Ford Five Hundred that I purchased certified used in 07'. Within a few months I started experiencing surging problems especially when the a/c was running. The dealer replaced the instrument cluster in 08' but did not fix the problem. On each return to the dealership they could not fix the problem. On my last visit to the dealer they cleaned the throttle body and said that would fix the problem. This did not fix the problem and they could not diagnose the problem. This problem has caused me to rearend a vehicle in 2009. Ford is not responding to the problem at all. After 3+ years of trying to figure out what the problem is I all but have given up. That is until today when the repair shop that I use on a regular basis hired a new mechanic who was able to diagnose the problem. The problem turns out to be the throttle position sensors in the throttle body. It took the mechanic over 2 hours to get to the bottom of the problem. The unfortunate thing is the cost of a new throttle body is over $500 then add labor. If I have the tb replaced there is no gaurantee from Ford that the new tb won't do the same thing. It is obvious that Ford has a problem with the tb and is not willing to resolve the issue and back their products.

Car goes to limp mode and jerks and accelerates abruptly.

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.

2007 Ford Five Hundred surges forward in parking lots, stop lights, going from park to drive or park to reverse. Almost hitting cars, pedestrians when it surges backward and forward.

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.

The contact owns a 2007 Ford Five Hundred. During an inspection, the contact realized that the plate nut was not placed deep enough into the panel, which prevented the fuel filler neck from being securely fastened to the fender. The dealer stated that the fuel filler neck adapter was not securely attached. The dealer attempted to tighten the bolts, however, it created a larger gap. The current mileage was 1,500 and failure mileage was 500. The consumer stated there is a still a 1/8" gap between fuel filler and neck adaptor and right rear fender panel. The dealer stated rear muffler hanger has corrosion. Updated 10/18/07.
