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.

I purchased the car used with the understanding that it had some issues with a misfire. Upon initial inspection I fount the car was throwing the code P0351 I cleared all faults and problem went away weks went by and problem started again but more sever during normal operation the car started shaking and shifting erratic I then came upon some K formation as to a recall Ford put in place stating improper calibration of PCM and tcm cause unnecessary interaction I the electrical system and malfunction of the vehicle

(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.

Suspension: Continuous rattle issues in the rear suspension. Bushings" sway bars?? who knows. No one can seem to pinpoint the problem. Happens only during driving. Consistent noise from the rear. Fuel: Problems with fuel sensor. Failed reading. All gauges light up. Run obd and all fluid levels / pressure fine. No reason for the failure. Dealership told me the throttle body was an issue and the sensor inside same. However, after numerous web based searches I found that throttle body issues are definitely an issue. Found that removing the air cleaner box for filter replacement can cause sensor issues. Why" since my last oil change I have had at least three failures here. This is dangerous, expensive and should be taken care of.

Bought the vehicle used in May 2010. Realized early-on that the transmission was not smooth, but willing to settle for less than perfection since it was a 2005 vehicle. In late 2012 or early 2013, I received 'recall' notice that PCM (I.e. - powertrain control module) could need to be reprogrammed due to stalling, herky-jerky transmission, etc. Took car to dealership, they ran diagnostics, charged me $100, and told me that my car wasn't effected because no error codes were noted and check engine light wasn't on. I was not happy, and refused to take my car to the dealership for repair. Problem persisted, until check engine light came on in October 2017 at roughly 125,000 miles. Took to local mechanic, was charged $150 for sensor replacement. Light came back on a day later. Took back, replaced sensor for free (nice!), but light back on a day later. Took to a different mechanic, was charged $250, replaced multiple sensors, light back on the next day. Took back to 2nd mechanic, when they shared with me that it was likely the PCM and the dealership would need to fix. Called dealership 3 days in a row, on hold for nearly an hour the 3rd time, was never connected to a service writer or tech, left 3 voice mails for service manager and was never called back. Researched issue and found NHTSA action number PE11018, where Ford initiated a customer satisfaction program 12N03 to extend coverage terms of repair of engine idle RPM surge caused by PCM needing reprogramming with software containing updated idle speed control. Per NHTSA, symptoms associated with the condition may include check engine light, diagnostic codes (dtcs) P0505, P0506, or P061B. Ford issued bulletin tsb 11-10-21 that included updated powertrain control calibration.

When I test drove this vehicle the RPM fluctuated and jerking as if it was a manual opposed to automatic as increasing speeds. There was a recall letter mailed to me a few years later and Ford dealership claimed the issue was resolved. Within a few days it began again. I have owned this vehicle 10 years with the same safety issue and have had to pull over numerous times when the rpms dont reset while on the highway to avoid accidents. I am now filing a formal complaint because I was rear ended due to this issue by a person with no insurance. How can I get this to go away before someone is hurt

I will never buy another Ford vehicle ever again!!!!!! I own a 2005 Ford Five hundred there was a recall in 2012 on the throttle body, a Ford dealer supposably cleaned the throttle body, well now its not driveable. We have since talked to several Ford dealers including Ford Motor Company, they all said it was our responsibility to fix the problem. I do not think it should be my responsibility to pay for this since the part was recalled !!! the car could stall at anytime while driving putting myself and my family at risk, I don't think much of this automobile company for not standing behind there product, I will never recommend a Ford vehicle to friends, family or even my worst enemy never never again!!!!

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.

Spark plugs have backed out of the aluminum head in this vehicle twice now. This second time, it was a plug in the back head hard to reach and it pulled some of the threads out with it. These aluminum heads should be recalled and replaced with steel heads.

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.

The dealer cleaned the throttle body to remedy the failure, but the failure recurred approximately one year later. The manufacturer was notified of the failures, but no solution was offered. The failure mileage was 100,000.

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.

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.
