The car is surging and feels like it is about to fall apart the car has low miles and the engine feels like the transmission is slipping but was told that this is a common problem with the Ford 500 I see there is a extended warranty but I just recently purchased this car and seems like the warranty expired and I see Ford is aware of this and refuses to fix this issue which is a hazardous condition and I feel like that im going to have to get a lawyer to get anything done because Ford is refusing to fix this issue with these cars and its very dangerous driving the car makes a loud knock and the engine drops back in and its breaking the motor mounts

Throttle body is defective due to build up within the throttle body's valve causing it to stick open or stay closed during reverse and forward driving. This in return causes a surge where at any unsuspecting moment the vehicle wood attempt to drive either in reverse or forward on its own regardless you physically pressing the brakes or the gas pedal. This is an obvious problem wiz 2005 2006 and 2007 Ford 500 and some models other than the 500 such as Ford freestyle Ford montego. This is a very dangerous issue and if not already will cause bodily injury or death. In my particular incident my vehicle have surged on a bypass causing me to almost rear end a large truck at speeds up to 70 miles per hour. There had also been countless incidents of my vehicle reverting into safe mode where my car I had slowed from 70 to 75 miles per hour down to 20 miles per hour within seconds. Both incidents have happened stationary in motion on city streets on highways and while turning. I was told the throttle body's electrical components are faulty and I was to pay $1,000 for a replacement part and installation.

I was approaching a red light and as I lifted my foot off the brake pedal..............the car accelerated abruptly and I was unable to stop causing me to pass red light, almost striking an oncoming vehicle that was making a left hand turn and driving onto sidewalk. Fortunately no one was hurt and an accident was avoided due to my quick response. The vehicle has accelerated abruptly on several other occasions. I was parked in a publics parking lot when I put my vehicle in reverse the vehicle once again accelerated almost hitting parked vehicle behind me. I was advised the throttle sensor was defective on 2005 & 2006 Ford Five hundred models and no recall yet! this defect causes vehicle to accelerate abruptly (even when parked) or not accelerate at all! there have been many reports regarding this issue and nothing has been done about it. When a life is lost or someone is severely injured..................is that when some action will be taken? according to reports even if the part gets replaced it does not guarantee it will not go bad again. Repairs have been known to cost between $450 to $750.

My Ford Five hundred throttle just shuts down, with no warning at all. I am afraid to drive it because it may shut down in traffic and some get seriously hurt. I have searched the internet and found more complaints same as mine. The problem is with a throttle body malfunction. Some thing should done before someone is killed!

I had a 2006 Ford Five hundred at first I loved that car then the battery stared going dead so I replaced the battery but it still did it so I had it looked at and they told me that it was the alternator going out so I replaced that but come to find out after 2 batteries and 3 alternators it was a wiring problem and finally the wiring problem ended up frying the com[uter in my car and it was going to cost me a whole lot of money to fix it and I didn't have that type of money it was more money then the car was worth I have talked to several people who say that they have had the same problem so a word to the wise do not buy a Ford Five hundred !!!

My car started lunging forward and dying when I was either idle or when I stopped and started up again. The throttle light and engine light came on. Sometimes when you would turn the ignition off and then restart the throttle light would go off. I have noticed some difference in fuel mileage. If I don't have my foot on the brake and it starts forward sometimes it would lunge, but not all the time. I have taken it to get the computer flashed by a Goodyear place in North little rock, ar. It has occurred several times more since they flashed it. That was about three weeks ago. The date now is Sept. 20. I wanted to report it, because with the lunging in heavy traffic, I am afraid that I will rear end someone all because of the lunging, which is unexpected.

On Jan 8, 2009, I had traveled approximately 1050 miles from Oklahoma to Ohio. While in Ohio, 6 inches of snow had fallen, and the roads were slick with snow and ice. In preparing for my return trip on Jan 11, the traction control and ABS warning lights came on, and there was a significant change in control and braking in the vehicle. Upon driving further, the transmission warning light came on, and the vehicle went into reverse with a huge "bang" sound and vibration. The vehicle's cvt transmission would not change gears in drive when the transmission light was illuminated. Upon turning the vehicle off, and back on, all lights would go off, and come back on within 5 minutes. After the 6th restart, the check engine light came on as well. The transmission light, after a few restarts, did not come back on. However, the ABS, traction control and check engine lights stayed on for approximately 650 miles. After that time, all lights went out, but the rpms went from 2000 to 3500 on their own while the vehicle was in cruise control on a flat road. That corrected itself about 100 miles later. Upon taking the vehicle to a dealer on my return, they told me that since no lights were on, and the vehicle was now acting normally, they could not duplicate the problem. My factory warranty expires in 14 days, and I am not sure if I'll be able to duplicate the problem to the dealer by that time. The service department blamed the malfunction on the cold weather and the snow, but the AWD vehicle with traction control was, to my knowledge, manufactured to deal with snow and cold weather. One does not need AWD, traction control or ABS during dry, warm days.
