Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

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.

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.

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.

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

Approximately two months after service performed 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 performed the service and they determined that the electric throttle control was at fault but was not associated with the service they performed 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.
