Throttle/accelerator the car unexpectedly accelerates without pushing the pedal. I have almost hit vehicles and pedestrians. It appears to be getting worse and more dangerous.

Throttle assembly problem. Very similar concerns as earlier recall which supposedly applied fix to the car a couple years ago. Except.along with unexpected acceleration while stopped a new problem arises. Motor acts as if it is not getting fuel and slows to a crawl sputtering to a stop.. wrench malfunction light comes on. After cars sits for a period of time wrench display goes off and car operates normally. Owners manual indicates that this may be a throttle assembly problem. Prior recall notice that has expired. On multiple web boards problem is mention with great frequency for the Ford 500. This happened to my wife on a side street at 15-20 mph. If it occurred on next bust street it could have presented a dangerous scenario. Ford dealer acknowledged this as a known problem, but Ford mfg only provided 1 time fix in recall & since the throttle cleaning fixed the problem at the time of recall no further attention was needed. I mentioned they did extend for recurring problem but that extension 2013. I don't feel a mfg should be able to time limit a problem resolution that they never permanently fix. By what I read on the web this is an issue that needs areal resolution.....cost me 900+ dollars to fix and Ford nothing!

I just purchased a 05 Ford Five hundred and was on my way from California to Georgia. As I was driving I noticed that when it would shift it would rev up even while slowing down. I also noticed that if the ac was on it got worse. I started doing research on this problem and found that I was not the only one having this problem. I have 4 children, I'm disabled and on a very fixed income and buying a vehicle that is safe is a must. Unfortunately, due to this problem, it is not safe I asked them what it was going to take for them to issue a recall, injury or even a death, and his response was that it was not up to them but up to the nhts. I have done a lot of research on this problem and there are many more people with these vehicles that have the same problem. I don't think the consumers should be liable to fix a defective part. Even a mechanic at a Ford dealership said that he doesn't know why they just don't replace it instead. Please help fix this problem before someone has to pay not with money but with there life! if I had the money I would replace it and have the ECM updated but that is not an option for me due to my finances. Please put out a recall on the throttle body and make the updates on the system free. Haven't we paid enough for our vehicles? these are things that are not due to negligence but defectiveness of a part. The company that made the throttle body is no longer in business so that should tell you something. And the updates shouldn't cost if it makes the vehicle run like it should. I believe if all owners of these vehicles come together we can actually fix this deadly problem. Why should someone have to pay with their life just for somebody to become aware of this deadly, defective part. So please help! they say the recalls come from you, so issue a recall and include the ECM update that goes with it. Thank you, concerned owner with children

Part of an ongoing series of issues with this vehicle (see earlier reports), initial symptom was the dash lights & needles shutting off intermittently (but now for extended periods). Vehicle then began showing random warning lights including "check engine", which was diagnosed first time as low fuel level sensors a & B. since that time I'd disconnected the battery on a suggestion of a mechanic friend and all the issues disappeared for a few weeks. Yesterday the check engine light came back, and the car was running poorly (creeping when first off brakes, not up shifting), when the dash was operable it showed alternating check engine/check transmission warnings, and vehicle was surging/lagging noticeably at highway speeds. I again did the battery disconnect last night, and the car is operating normal today, but I'm sure it will recur shortly. I am hesitant to take it to a dealer as this sounds like a significant electronics issue, and I have already read up on the Ford tsb 06-17-9 that is documented online, not all of which aligns with my issues. Had the battery reset had no impact on the problems I would say it's a mechanical matter, but it seems clear its a computer or electrical issue.

Driving at 30 mph on secondary street when vehicle lost power and service engine light came on. Coasted to side of road tried to push accelerator to raise RPM. RPM remained at 1000 and not enough power to pull back on the road. I turned vehicle off and started the engine back up when power was restored and service engine light went off.

Since 2007 the car intermittently will periodically lung forward and it is almost impossible to control the car. This has happened several times since June 2007 (88,000 miles). Even hard braking does not necessarily stop the car...I have had to put the car in neutral the engine revs up as if I am touching the accelerator (and my foot is not on the pedal) and I shut the car off. Turning the car back on does not necessarily remedy the problem. In addition, the car routinely goes into fail safe engine mode or cuts off while I am driving at a reasonable rate of speed both on rural roads and highways. This car is a hazard to drive, more so in the warmer months...my thought is something must get overheated but what I do not know.

Vehicle goes into fail safe mode and lurches violently in forward and reverse without touching the gas pedal. Started at 45,000 miles infrequently and now occurs about 3 time a month. I am going to replace the throttle body to see if it corrects the problem.

Car goes into "engine failure mode" while driving. Engine dies and power brakes and steering go out. Went to dealer for injector flush and and throttle body cleaning plus reprogram PCM. Still get "engine failure mode". very dangerous. My only car. Have been told this is very common problem with these Ford and yet no recall. I am out $340 and no lasting fix. At dealer 5/18/1L. What is wrong with getting this repaired correctly. Went to maroone Ford, 1333 N. federal hwy. Fort lauderdale, fl 33304. Car now sitting in my garage. It won't run and I'm afraid to drive it. It starts but is very rough and won't respond to gas pedal. Can I try and drive it back to the dealer at 10 mph without damaging the engine" I am retired and don't have the big bucks to repair this car. Will Ford pay for the repair" the failure mode has happened 4 times since the repair but has "fixed" itself until today.

My 2005 Ford 500 began to surge when changing from park to reverse and also when changing from park to drive. At time it would change from 800 RPM to 1500 to 2500 RPM. Very scary in tight quarters and in a parking lot. Other times it thought it was a Toyota and just take off.fault codes did appear and the dealers first try did nothing to fix the problem. The last time was on the interstate. It terrified my wife. We dropped it off again at the dealer and was told that the repair part would take 14 days. Does Ford have that many problems ? I checked the internet and many Ford products are having throttle body problems. The replacement part was completely different from the original.

When vehicle is in drive or reverse and there is a load on the engine (A/C on high) and you turn the steering wheel, the engine accelerates on its own. This happens every time I go to turn at a low rate of speed, in drive or reverse. The garage said it was the throttle body that needed replaced. They also told me this was a common problem and the part was on back order.
