I OWN A 2006 FORD FIVE HUNDRED. THIS PAST WEEK I HAD AN ISSUE WITH MY CAR LUNGING FORWARD WHILE STOPPED AT TRAFFIC LIGHTS AND ALSO WHILE BACKING UP. MY HUSBAND WAS PARKING THE VEHICLE AT A RESTAURANT AND WHILE THE BRAKE WAS ENGAGED THE CAR LUNGED FORWARD AND HIT THE CURB. LUCKILY THE VEHICLE CAME TO A STOP ONCE IT HIT THE CURB. WHAT IF THE CURB WAS NOT THERE BUT, A PERSON WAS. WE LEFT THE RESTAURANT AND WE WERE AT A STOP LIGHT. MY HUSBAND SAID HE FELT THE CAR WAS GOING TO TAKE OFF. WHEN WE GOT HOME SAFELY ( THANK GOD ) WE WENT ONLINE TO INVESTIGATE. IT SEEMS AS THOUGH WE ARE NOT THE ONLY ONE WITH THIS PROBLEM. THE FORD FREESTYLE HAS MANY COMPLAINTS AND THE MERCURY MONTEGO AS WELL AS THE FIVE HUNDRED HAVE COMPLAINTS AS WELL. IT SEEMS TO BE A PROBLEM WITH THE THROTTLE BODY. MY HUSBAND CALLED THE DEALERSHIP AND GOT THE PART FOR ABOUT $560.00. LUCKILY MY NEIGHBOR IS A MECHANIC AND WILL BE PUTTING THE PART IN FOR US. THIS WILL HOPEFULLY CORRECT THE PROBLEM IF NOT, I BE FILING ANOTHER COMPLAINT. PLEASE DOCUMENT THIS PROBLEM AND HOPEFULLY IN THE FUTURE SOMETHING WILL BE DONE ABOUT IT BEFORE SOMEONE GET SERIOUSLY INJURED OR EVEN KILLED ! *TR
