Problems with 2007 Ford Five Hundred POWER TRAIN

Tl* the contact owns a 2007 ford five hundred. while stopped with the brakes depressed, the vehicle suddenly jerked forward. the vehicle would also stall intermittently after the jerking. the vehicle was taken to the dealer for diagnostics. the technician replaced the transmission kit but after the repair, the failure persisted. the vehicle was not further repaired. the approximate failure mileage was 90,000.

Car: 2007 ford 500 limited. moving shift lever from park to reverse or to drive, after about 1 second the car "lurches" forward or backward. i keep the brake locked down when changing gears for several seconds until im sure it wont jump but i have to remember to do it. this is dangerous. when this first started happening, i almost ran over someone. i hope you can identify the problem and let me know or have ford put out a safety recall and a fix for the problem. thanks *tr

Car was jerking on acceleration, was told there were no codes even though the light was flashing it is still doing it only worse the light is on solid now and the car is now out of warranty. it would also jerk when taken out of park or when in traffic sitting idle, once i thought i was rear ended. i took it to the mechanics and they told me this is 'normal' behavior and there was nothing wrong with the car. it will not even stay running now when warm and it dies. *tr

With a/c on i start car. put car in forward or reverse. engine surges then settles down, this is quite dangerous. brought it in for warranty help. was informed that it may be throttle body and throttle body is not covered in drivetrain warranty. ford, are you kidding me? vehicle has 41,170 miles, the warranty for this item apparently ran out at 36,000 miles. this is a safety issue more than anything. this is a huge safety issue. putting car in gear and having the engine surge is a recipe for disaster. *tr

Engine idle speed is excessive at intermittent intervals while transmission is in reverse, causes vehicle to inadvertently accelerate at inappropriate speeds. local repair shop scanned vehicles repair codes, determined it to be a transmission failure. authorized dealership, said nothing was wrong with the vehicle after they scanned it. vehicle, went into a "creep mode" immediately following one of the instances, but the computer reset itself after several minutes.*tr

It started out as a loud thump that rocked the car when shifting into gear... that has continued but now it also when accelerating hesitates then you hear the thump and then it will accelerate. i have had this at my dealership 3 times now and they refuse to fix it. they continually say the cannot "recreate" the problem. i also have a airleak in the car that is so loud you cannot hear the radio when driving on a interstate. they are blaming that on the antenna on the outside of the car. i have less then 20,000 miles on this car and a extended warranty. i have no idea what to do to make them fix it. i worry about the safety of this, i have a newborn and am afraid if it is the transmission, which it sounds like, that it could seize up and possibly cause a accident. *tr

Purchased a new ford five hundred in 2007. have kept up with all regular maintenance. after putting about 20,000 miles on the vehicle, i started having a problem with sudden acceleration. i would come to a stop at an intersection, mailbox, or drive-thru and let my foot off the brakes and the car would "jump" -- accelerate on its own. my foot would not even be on the gas pedal. i took it to the ford dealership and was told that the transmission had to be "reprogrammed". i specifically asked could it be a problem with fuel system and was told no. i had the work completed but the problem persists to this day. i have had several near misses with rear end collisions. finally as i was entering a parking space, the car accelerated on its own and hit a post in front of the parking space.

The transmission will engage the engine and leap forward without giving it any gas. no creep, just leaps forward several yards. .. updated 08-27-12 *bf
