I was at red light person crossing road I was I. drive foot on brake, rpms shot up engine reeves cat lunged forward I pressed harder in brake almost hit person. At the time no warning lights. Then at pharmacy drive thru w car I. from and I. back of me car did same thing. I had to press brake hard to prevent moving hitting car in from of me. I was in drive but foot on brake! no warning lights at time. Had throttle body replaced still had similar problems progressing little did I know when throttle body is replaced has to be reprogrammed by Ford! spent so much money and time trying to figure out problem. This is a flaw w Ford 500 2005 throttle body many complaints and test does never issues recall, unsafe. I could have killed someone.

Transmission has very hard and delayed upshift and downshift making it difficult to control speed when accelerating and decelerating. RPM gets stuck around 3000 at lower speeds and upon engaging into gear has made my tires squawk with a sudden lunge in speed and same problem when trying to stop, the car lunges forward. It acts as though it is in neutral but then when it engages into gear sudden changes in speed occur causing rapid acceleration or deceleration. The problem gets worse after the car is up to normal operating temperature. It doesn't occur as often at colder operating temperature. This problem makes it difficult to get back up to safe highway speeds after having to stop for traffic or red lights as well as hard to get up to speed to safely merge into traffic from an on ramp. As far as "when" this happened it is every day as I drive daily.

(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.

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.

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.

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!!

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.

- Weston, WV, USA

The contact owns a 2005 Ford Five hundred. When in the drive or reverse position, the vehicle accelerated independently without warning. The failure occurred intermittently.

- San Antonio, TX, USA

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.

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.

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.

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.

- Jacksonville, FL, USA

I was driving in town going about 40 mph when the car lost all power, then engine failsafe mode displayed on the information center and a little wrench was also displayed. With no power steering, I had to pull over quickly in lunchtime traffic. After stopping the car, I waited a few seconds and restarted it. No problems with it until the next day when the check engine light came on. I have also noticed a mechanical smell coming from the ac. It appeared, at first, that this problem had come out of nowhere when I suddenly remembered two occasions when the rpms suddenly stuck on 3000 and would not stop until I put the car in neutral. Also, when using cruise control, the whole car shakes and stutters slightly when going up or down very slight inclines.
