3 Vehicle Speed Control problem

Failure Date: 08/18/2019

(etb) electronic throttle body on my car causes an acceleration that makes the car jerk forward. I've almost hit a wall, and god forbid this happens on the highway I could cause an accident. Its unsafe and should be recalled. Poor design I guess but it's not worth my life. This happened while idling in drive thru when I tried to go forward it idled really high then dropped down. Would bot accelerate afterwards.

4 Vehicle Speed Control problem

Failure Date: 01/11/2018

I have researched online and a lot of people with my same car are having the same problem. While driving my whole dash board goes out . I can no longer see how fast I'm going. Everything goes to 0 the gas goes to e and my reverse lights stay on until the dash board comes back up. If and when it comes back on my check engine light will be on. This has been happening every since I purchased the car 3years ago on and off.

6 Vehicle Speed Control problem

Failure Date: 07/14/2016

I have been having trouble out of my car and did not know what it was. I could be driving and the accelerator wouldn't have an power. I noticed that the message in my dash read: failed safe mode. I was in traffic when this happened and I had my children in the car and I afraid,we would be rear ended because though,the car was still on,I had no power to continue. I turned the car off and back on and it continued to go into fail safe mode,then I noticed there was a wrench tool,also in the message board. After being in the middle of the road for 20 minutes,the car finally crunk up,so I could move it out the road. As,I crunk the car,I didn't have my feet on the accelerator but I immediately had to put my feet in the break because they car was mounting as if I was pushing the gas. When I finally got ready to pull off barely touching the gas,it jerked off really fast,causing me to almost loose control of the vehicle. I was terrified! I got the car home and called my mechanic. He told me to bring to him the next morning. I get up the next morning to take it to the mechanic and it repeatedly went into fail safe mode,where I could not go anywhere. I finally got it to go after an hour and it did the same,as I was attempting to get it to the mechanic shop. The mechanic tested it and said,the throttle body needed to be replaced. I was also,told,that there was a recall on these same cars for the same problem as im experiencing. I did some research myself and there was a recall on these Ford 500 for throttle body. Im just not sure,what year they were recalled. The recall number is 12n03. I hope I have explained in full detail,as,im just thankful,that I,my family or others were injured,before I figured out how dangerous this car is!!.

7 Vehicle Speed Control problem

Failure Date: 04/12/2016

The transmission disengages at various speeds even on the interstate at 55+ mph causing it to lose power. You must be able to get it stopped on the side of the road and shut the car off and then restart it to correct the problem for a short period of time.

8 Vehicle Speed Control problem

Failure Date: 08/17/2015

While driving dash lights, speedometer, tachometer, gas level, and temperature go out for several minutes at a time. Reverse lights come on and airbag light comes on. This is dangerous; unable to tell speed! per internet research this is happening in several Ford models and stems from a bad solder joint.

9 Vehicle Speed Control problem

Failure Date: 06/30/2015

When coming to a complete stop with my foot on the brake, the car continues to jerk and drive. It also does it while reversing which in both cases has almost caused me to run into the car in front or behind me. It takes a while to pick up speed after stopping. It jerks while picking up speed. The passenger door inside handle does not close on its own. It rains in the car on the driver's side. The front driver's side panel keeps popping out of place. . The thing under the car that keeps you from hitting the curb, is falling apart.

10 Vehicle Speed Control problem

Failure Date: 05/01/2015

I was in heavy traffic and the car just stalled out on me while sitting at a light. Had to put my hazards on and try to restart car, restarted and then as soon as I put it into drive it stalled again. This happened 3-4 times until I could move to the next light and stop and go through the whole process all over again. Finally got on the highway and got home. Thought it was a fluke. Happened a second time while picking up children from daycare. Stalled out while at low rpm and would not restart. Had to have it towed. Had fuel filter replaced. Happened a third time at the store. Had to have it towed. Towed it to the dealer and the dealer spent over 6 hours to come to the conclusion that throttle body needed to be cleaned and pcm reprogrammed/updated. Without much confidence, they returned the car to me and said they could not replicate the problem. Drove it for a day and then had the same problem in traffic when at low rpm, with children in car at intersection car stalled out! finally got it started by holding brake and pushing on accelerator while putting it into drive so that it would not stall out. Drove it home and have not taken it out since. Expect the throttle body needs to be replaced but don't want to spend any more money on "diagnostics" when Ford knows this is a problem part and they need to stand behind it!!!!! they have put my family at risk more than once and they need to fix this problem before someone gets hurt.

11 Vehicle Speed Control problem

Failure Date: 02/09/2015

One day driving my Ford Five Hundred as I am gettin on the freeway the car didnt accelerate effectively activating rpm surges but the car wouldn't speed more than 30mph doing so taking long nearly causing a accident in addition to slowing flow of traffic after finally getting home and parked the next day the car didn't start it would crank but wouldn't start I had a mechanic come look at the car everything was in order the pcm would also click when trying to start after doing research I discovered NHTSA had a recall for Ford Five Hundreds 12n03 and in the summary it included throttle and pcm reprogramming and cleaning or replacing the throttle body. Therefore I brought the car to a Ford dealership and they confirmed theses being the cars issues however Ford dealership said that my pcm needed to be replaced not reprogrammed which is not covered under 12n03 protection program.

14 Vehicle Speed Control problem

Failure Date: 05/04/2014

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.

20 Vehicle Speed Control problem

Failure Date: 05/28/2013

The automatic gear shifter has a rubber mat under the metal plate with the prndl gears listed. It is difficult to shift out of p and then then you reach r and d the mat has bunched up so much that the metal plate telling you what gear you're in pops off. This is an extreme hazard, as I back into the road and then to put it in d, not knowing where d is because the plate pops off, I could be hit. I also have a 2008 Ford taurus experiencing the same problem. I called Ford and they acted as if there were no previous issues. This is certainly not true. This will cause an accident or fatality.

21 Vehicle Speed Control problem

Failure Date: 05/05/2013

Approximately two months after service preformed under NHTSA campaign pe11018 the vehicle began to accelerate irregularly and then it placed itself into "fail safe" mode and illuminated the check engine light. Vehicle was returned to the Ford dealer that preformed the service and they determined that the electric throttle control was at fault but was not associated with the service they preformed on the same component just weeks earlier. Dealer contacted Ford motor CO and they also claimed the two were not related regardless of the similar claims found online.

27 Vehicle Speed Control problem

Failure Date: 10/13/2012

My car surges. It is mostly at idle speed. It's dangerous. I was at a drive through and a janitor was sweeping. My car surged and I literally stood on the breaks to prevent running over him. At the drive through it surged forward and I had to stand on the breaks to prevent it from ramming into the car ahead. It occurs more when air conditioning is running but will occur without ac on. I the local dealer replaced the throttle body recently but it still surges. It occurs when pulling to a stop at the lights or at the drive through as you slowly move forward. It happens when pulling into a parking spot or when backing up. I've seen news about the problem with the Ford escape. My Ford 500 is also affected and weighs a whole lot more. If this thing surges forward it could do some serious damage.

28 Vehicle Speed Control problem

Failure Date: 09/01/2012

Out side air temp was approx 96 degrees so ac was on . While shifting into reverse the vehicle lunged so hard it was uncontrollable,and unstoppable, if some one had stepped out behind me they would have died as I could only stop reward movement by shifting into drive. This occurred three times trying to get out of a parking space at a crowded mall. The vehicle then stalled. The lunging was so fast the brakes could hardly hold the car from moving in reverse. In checking there is a service bulletin TSB-05-25-13 from Ford motor company on this very issue but no recall, also many incidents/accidents recorded in this regard. If I was not prepared enough during this incident in a crowded parking lot some one would have died, this must be addressed b-4 someone is run over. Currently Ford has no comment. Please contact me for further details.

29 Vehicle Speed Control problem

Failure Date: 08/16/2012

After having turned onto a 35 mph street, having only reached 30mph, the rpm's shot up to six and the car accelerated to almost 40 without the gas peddle having been pressed. If there were another car stopped or a person in front of us they would have been hit. Another time the vehicle was at a stop light and again with out warning the cars rpm's shot up to about six. If my foot had not been applied completely to the breaks I would have been in a busy intersection resulting in the car having been totaled, death of more then one person. This is not safe.

30 Vehicle Speed Control problem

Failure Date: 07/26/2012

This happens frequently almost daily in the summer. But on a hot day (90+) when moving from a stopped position out of a parking spot or around a corner, when you lightly have the brake pedal depressed if you turn the wheel slightly (ie backing out of a tight parking space) the car will lunge violently and aggressively in what ever direction you are traveling, sometimes so aggressively it will stall the vehicle out and then go into a failsafe mode. This is very dangerous as you could unexpectedly hit someone walking around the car at a stop sign or crosswalk. I have also found numerous other complaints on various blogs, forums, and other sites. Everyone basically stating the dealer gives them the run around. And as long as it is a hot day I can duplicate the results continuously, and would be more than willing to show this to someone else if possible. I am typically not one to complain, but I feel very strongly about the safety of this vehicle, especially since I have a 3yr old daughter.

31 Vehicle Speed Control problem

Failure Date: 07/24/2012

We were driving down a highway and went to get back to speed after passing through a speed zone. I noticed a decrease in power and looked at the information screen. The fail safe mode and the "wrench" icon was on. I pulled the car over and turned it off. I then turned it on and the car acted normal. It has happened twice since the first incident. My wife took it to the dealership and Ford cannot duplicate the problem and the issue does not throw a check engine code or leaves any type of electronic history of the issue. I cannot allow my wife to drive this car because she is seven month pregnant and cannot have her drive it if the car breaks down due to this issue.

32 Vehicle Speed Control problem

Failure Date: 07/01/2012

During warm weather with the a/c operating, the rpms surge and the vehicle lunges in the direction of the transmission lever selection (forward or reverse) when moving the shift lever from park to drive or from park to reverse with driver's foot on the brake. Engine rpms surge up to approx. 1,500 from idle at a dead stop without input from accelerator pedal. Different indicator lights come on and often the engine dies after the surge. If driver does not keep appropriate pressure on break pedal while shifting from park, the vehicle will accelerate without input from gas pedal. This surge also happens when decelerating to a stop. Vehicle slows down and rpms decrease to approx 600 (idle), and with pressure applied to brake pedal, engine rpms will increase, without input from accelerator pedal, forcing the driver to increase pressure on brake pedal or risk uncontrolled forward movement. Initial reports indicate a faulty throttle body as referenced in NHTSA investigation # pe110818.

33 Vehicle Speed Control problem

Failure Date: 06/21/2012

The contact owns a 2005 Ford Five Hundred. The contact stated that while driving 5 mph, the engine light began to illuminate. The vehicle was taken to the dealer for diagnosis and the contact was informed that the vehicle would need a new throttle body. The vehicle had not been repaired. The failure and current mileages were 101,934.

34 Vehicle Speed Control problem

Failure Date: 06/16/2012

Throttle body malfunction. Engine reves up while placing the car in drive or reverse without touching the gas pedal, up to 1. 5 on the rpm's on the speedometer. This is very scary, a child crossed in front of me while I was waiting at a stop sign. Foot was on the brake but all of a sudden it just reved up. It lunged forward and I hd to really put that break on. Scared me and the child to. I bought the car new and had all service done from the Ford dealer in the service person there told my husband that this part "throttle body" was made by the same manufacturer that made the Toyota parts that went bad "sticking gas pedals" ? and that Toyota recalled this dangerous issue and fixed it. Unless my husband misunderstood this gentleman, which I don't think he did. I spoke to Ford and placed a complaint and they told me that there had been complaints, but there was no recall issued as yet, but hold onto my receipt in case there is a recall issued in the future. This will cost $850. 00, "which I feel should be picked up by Ford". Pressing normally on the breaks is not good enough, you have to almost put it to the floor so that you do not move and pray that it doesn't lunge forward in the transition from break to gas pedal. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

35 Vehicle Speed Control problem

Failure Date: 05/24/2012

My wife, son and I were driving. The vehicle had random acceleration while at full stopped. About 10 minutes later after a full stop the vehicle had another acceleration while foot on brake and the vehicle stalled out. Once stalled out the computer displayed the following error "fail safe engine". After doing an online review I noticed that many other Ford Five Hundred owners having the same issue and seems to be caused by "throttle body". Please note that whenever the vehicle is on park and put into reverse, the higher acceleration takes place. I always have to be extra careful. I have to be extra careful while driving as I am afraid for acceleration and stalling out in the middle of the road.
