Problems with 2005 Ford Five Hundred FUEL SYSTEM, GASOLINE

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. *tr

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! *tr

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. *tr

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 *tr

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. *tr

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. *tr

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. *tr

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 fords 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. *tr

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. *tr

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. *tr

Ford 500 se 2005 . put the car drive or reverse and the car lunges. push down on accelerator and car lags . throttle body defective. happens every time i drive the car. part needs to be replaced back ordered until december. *tr

Purchased my 500 9/05 it only had 5 miles on it. 6 months later loud explosion in engine which began to leak some sort of fluid got the car towed to dealer purchased was told a/c leaking oil and they had to replace the manifold i wasn't even using the a/c was march!!! my dash console had to be replaced since it was defective and the computer also had to be reprogrammed since the car wouldn't start in 30 degree weather this happened in jan06......my fuel straps were replaced due to recall and my door locks were replaced due to recall and i had 22k miles when the back brakes began making a terrible grinding noise when backing up took to dealer said that although car is under warranty brakes are under wear and tear and would not be covered now which didn't make any sense since the front brakes were good how could back brakes go bad before front brakes unless you only drive your car in reverse????? i paid the $400 to fix since was informed 500 rotors cant be turned ever will always have to purchase new ones......then 6 months later brakes were recalled and i did request refund which i did receive. however i now have 44k no longer have warranty since expired and i didn't buy extended warranty brought car in to ford since transmission light was turning on and off along with the traction control light then had trans censor replaced was told that was problem then 2 days later light still turning on and car will not reverse took into dealer again was told trans axle broke in half and need new trans which costs $5300 car is only work 9k!!!! ford company said they will offer assistance only of 3k since out of warranty they also informed me that had i purchased the extended warranty i would only be paying $100 nothing like throwing that in your face. i have no choice but to pay it need a car and am a single parent of 2. also back doors trim is coming apart passenger since is completely rotted out. *tr

Ford five hundred '05 brakes applied in heavy braking situation on highway and the fuel cut-off mechanism activated. car would not restart, had to be towed into dealership. dealer reported that the wiring for the cut-off switch, by the front passenger foot area had come lose. re-set of mechanism not possible, had to have the wiring re-done and re-configured by the dealer service area. this is a definite design flaw and should be investigated as it could occur when car is operating at highway speeds if it is exposed to passenger foot bump. *tr

Went through 3 puddles of water ,car stalled had to be towed to dealer , dealer found fuel line detached. very dangerous. *tr

Lost power while driving; would sputter on take off from a stop; would hesitate while pressing accelerator; stalled; took vehicle to ford dealer -- they replaced the fuel pump. *jb

Dt*: the contact stated while driving from a stop sign, going less than 5 mph, the vehicle stalled suddenly. the vehicle was towed to the dealership where they determined the fuel cutoff inertia switch was bad and needed to be replaced. on 6-14-06 the same problem occurred while in the middle of the road going 5 mph. the vehicle restarted only for a short time allowing the contact to get out of the road. once on the side of the road, it stalled again. the vehicle was towed to the dealership who determined the problem was with the inertia switch; which was partially detached. the dealership put a strap around the switch. on 6-16-06 the dealership was asked to start the vehicle and tap the passenger side floorboard where the inertia switch was located. the vehicle suddenly shut off again. the service dept. manager tested other ford 500s on the lot to see if the same thing occurred and it did. the dealership determined there was no guarantee the same thing would not happen again.

Dt*: the contact stated the fuel gauge was sticking intermittently and would not indicate the proper amount of fuel in the tank. eventually the gauge would not operate at all. the dealership determined the problem was with the fuel quality and added fuel enhancers to the fuel tank. currently the fuel gauge has been working properly. the contact maintained if there was actually a problem with fuel quality the proper authorities should be notified. updated *ak updated 6/20/2006 - *nm updated 06/19/06- the dealer told the consumer that sulfur was in the fuel that he was using, which was causing the problem. *jb
