2007 Ford Five Hundred sel accelerating and lunging while pulling into a parking spot, garage, or drive-thru lane. Occurs in drive and in reverse. Sudden acceleration lunges the car several feet and has caused several near-miss incidents. Can't park too close to another car in parking lot or garage or pull up behind another car very close at a red light for fear of car lunging into the car in front. Very scary not being able to control this. Afraid to coast into parking spot without foot on brake for fear of hitting someone or some thing.

2007 Ford 500 transmission problem. Driving on interstate and the transmission starts to buck out of the blue. Cannot pass people on normal roads or barely make it up hills, acceleration is very slow. Failure occurs every time the car is driven, getting worse every day. It used to occur at higher speeds, now it is happening anywhere above 30mph. Have not done anything to correct problem, been reading up on it; and everyone has the problem and there is no "cheap" fix yet.

Car lurches at inappropriate times. This occurs mostly when putting it into reverse from park.

The contact owns a 2007 Ford Five Hundred. The contact attempted to start the vehicle but it would not shift into drive or reverse. The gear shift knob moved and the engine revved but the gears would not change. The vehicle was towed to an authorized dealer who was able to get the gears to change but could determine the cause of failure. The failure mileage was 35,000 and the current mileage was 40,200.

My wife has a 2007 Ford 500. Since 40k miles, she's had continous problems with the vehicle surging at inappropriate times. I also had a 2007 model 500 as a company car. I began experiencing the same problems in/around the same mileage. Several other people with our company were also driving 500's and experienced the same problems. Ford sent a representative to green Ford in greensboro, nc and diagnosed the problem as the electronic throttle body. The vehicles were repaired out of warranty. The problem has gotten progressively worse. As a result and after the vehicle almost surged into our daughter, I took my wife's car to the Ford dealership today. The service rep acknowledged "some problems" with the throttle body, but advised it was not a problem in all vehicles. I told him about the same problems with my 500 and the problems with the other company cars. I even offered to provide him the name and contact information for the other dealership, but was told they were in a "different district" and had a different reprsentative. I asked if they communicated with each other to which I received an intelligeible response. I work as an insurance investigator and will ensure this problem is not overlooked. I've almost wrecked the car 3 times in our carport and parking lots as a result of sudden surge. It appears Toyota is not the only car company with sudden surges and/or problems with throttle problems. We've been fortunate that nobody has been injured, but I don't believe someone should be hurt or worse before a company does the right thing and takes a proactive response to a known problem. Thank you.

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.

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.

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.
